Lauren had the workouts in categories for whatever you need for the day. She even has workouts set for the week if you have no clue what you want or need to do. She explains things in a way anyone can understand them. Her experience and her knowledge of being an instructor and MAT help me know that I am doing what my body needs. She helps point out that we need to listen to our body rather than push through it. Some days I don’t feel like I did much in the workout but I feel it the next day. This app is for everyone experienced and not experienced. **Developer response:** Wow!! This is such an amazing, detailed review. Thank you so much for your wonderful feedback! It is great to hear that the explanations are clear and easy to understand. I love that the message of listening to your body resonates with you! This is so very important! I am so glad that you are seeing the value of a gentle, intelligent progression with exercise. Your review means so much to me! It is such a gift to be able to work with amazing people like you! ### 5/5 — The best of the best *2024-09-12* Lauren is caring , listens, knowledgeable and has kept me mobile and active after 2 back surgeries and 2 shoulder surgeries . Doctors told me I should stop being so active and find other sports that are easier and shorten my activity time . Lauren , who has been through a lot of injuries herself and understands athletes, (being one herself ) has changed my world and kept my outlook bright. Her MAT sessions as well as her phenomenal vast selection of training sessions on her app/tv are incredible. I wish I could give her 100 stars **Developer response:** Colyn I feel so blessed to not only have you as a member of FIS TV, but to also see you in person for Muscle Activation Techniques. I am so glad that you see the value with this app in keeping you strong between sessions and seeing your body getting stronger! Your review is so inspirational to others who have suffered from multiple surgeries, feeling as though they will never get back to their favorite activities. I am so glad that you feel so optimistic about your future and the importance of keeping your muscles healthy! Thank you so much for this 5 star review!!! ### 5/5 — Gratitude *2024-06-06* I am so thankful that Lauren had the initiative to take on this project to have her lessons online, and has followed through to make this plan so comprehensive. I’m getting exactly what I need to recover from an injury. I’m also building strength, balance and coordination. There are too many benefits to list!! I’m also seeing Lauren in person for Muscle Activation. Yay to healing and getting strong at the same time! ❤️Patricia **Developer response:** Patricia Thank you so much for this amazing 5-star review! I am so happy that you feel that you are getting what you need, recovering from your injury with the feeling of strength. It is such a joy to work with you and to have you as a client! I am happy that you feel that FIS TV is comprehensive and helpful! It means the world to me! ### 5/5 — The Only Fitness App To Have… *2024-01-25* I've been using this workout app, and I can't praise it enough. Lauren, the instructor, is incredibly knowledgeable and provides clear guidance throughout the sessions. Her expertise shines through, making each exercise effective and safe. I appreciate how she tailors workouts to different fitness levels, ensuring everyone can benefit. Lauren's helpful tips and encouragement have truly elevated my fitness journey with this app. Highly recommend! **Developer response:** Whitney Wow! This is such a wonderful review and I am so grateful that you took the time to relay your experiences with FIS TV! It is so important to me to make others feel confident in taking care of themselves and I am so glad that you found the instructions to be clear and effective. I also appreciate the testimonial that any fitness level can benefit. I am so happy that I get to work with you in this way and cheer you on! You are amazing!! Thank you!! ### 5/5 — Love love love *2024-01-24* I spent many years working out doing things that weren’t exactly right for my body and needs. I didn’t know what to do or where to turn. I was lucky enough to find fitness integrated science TV by accident on Instagram and immediately came to find their app. The quality of the workouts are awesome. It’s just like having a physical therapist with you during your workouts. It has completely changed the way that I exercise and my thought process. I highly recommend this app. It is definitely worth every penny. **Developer response:** Thank you so much for this AMAZING review! I created this app to be a resource to others to recover from injury, heal chronic pain, and improve the health of their muscles. To know that you feel that this app worked so well for you in addressing your specific needs means the world to me! I love teaching others how to take care of themselves better and hearing that the methodology of FIS TV has been so beneficial to you is the best! I am truly grateful for your review!! ### 5/5 — Game changer! *2023-12-11* As a personal trainer I recommend this App to ALL of my clients! It’s by far the best way for my clients to keep their joints healthy and strong so we can get the best benefit from our training sessions. I personally use this app daily and have noticed such a difference in my mobility and overall strength. This app is CRITICAL for those that are coming off surgery or have been told they can never do something again because of damage they may have caused. But by no means is this app ONLY for injured. Even if you are a fit athlete you will be amazed at how this app can keep you from injury! I love Lauren and cant recommend this more! ### 5/5 — Great content *2023-12-10, version 8.321.1* I love the isometric exercises. Lots of content and easy to follow. ### 5/5 — FIS App for Certified Personal Trainers …….. THE BEST. *2023-11-29, version 8.321.1* As a personal trainer many of my clients come to me with injuries or issues from previous gyms or activities. It’s always a challenge to “fix” any issues as fast as the client would like which is why Lauren’s App is so critical to the overall program I design for my clients. The isometric, resistance and additional strength training videos work hand in hand with the work I can do in the gym with machines and extra weights. I give my clients suggestions on different videos so that the work we do in the gym is enhanced and keeps us on track to continue to make progress! I personally do these videos every day which has been incredible for my own personal development and strength. Weather you are brand new, just coming out of surgery, or simply need to keep your muscles and joints strong…… this is just the App you need and 1000% worth every penny! ### 5/5 — Strength and Mobility = pain free *2023-11-10* I was introduced to Lauren and her muscle strengthening approach to fitness in December 2018. I suffered with regular crippling lower back strain for 30 years following an injury aged 19. No more!!! Having this wonderful app gives me access to Lauren’s meticulously crafted workouts anytime I want to care for my body with specific, intentional movement. I can step onto the mat feeling blah and sore from all the sitting I do in my job and after even just a short workout I feel SO MUCH BETTER! I take Lauren with me when I travel via the FIS TV App since there’s plenty of prop/equipment free workout options on there. I hope lots of people discover Lauren and her intelligent and thoughtful approach to fitness as we age. Let Lauren help you take charge of your mobility and strength! **Developer response:** Kate thank you for writing such a glowing review of FIS TV! I am thrilled that you are able to recover from the effects of your back injury using this program. I intended for this to be a service that can be easy to use and convenient for people to break through the cycles of chronic pain in order to get back to doing the things they want to do! I am so happy that this was your experience! I am glad that you re able to find what you need and that you are feeling better! I appreciate you sharing your journey and value the opportunity to work with you!! ### 5/5 — Lauren is the best! *2023-10-03* As a former college athlete who was used to doing whatever I wanted, whenever I wanted and however I wanted when it came to my physical workouts, I finally hit a wall in my late 30’s. After enduring a lot of trauma and stress, and finally having a major hip surgery, I found myself not able to do ANYTHING physical related. As a PE teacher, this was not only a problem in my profession, but also in my daily living. I couldn’t do the things I love, and I couldn’t sleep or even ride in a car. I tried everything- personal trainers, PT, massage therapy, chiropractor, injections, ect. NOTHING worked and I found myself in the darkest depression after 2 years of not being able to workout. And then I met Lauren. She has not only helped my physical body, she has helped me to gain new knowledge about caring for my body and helping me to age beautifully and gracefully. I thank God everyday for leading me to Lauren. She is not only knowledgeable, and amazing at what she does, but she is genuine and her ability to relate to her clients sets her above the rest. She truly cares and wants to help people. I am not a morning person, but over the last few months, it’s easy to set my alarm to wake up and start my day with Laurens workouts on the app. It literally has transformed my life and has helped me regain not only strength, but confidence in myself as well. I could go on and on. An easy 5 stars for the app AND for Lauren. You will not regret purchasing this app- it’s a STEAL for what you get!! **Developer response:** Tami- Thank you so much for taking the time to write about your struggles! I can only imagine what it was like to be an athlete and have surgery on such a major joint! I am sure you are an inspiration to your PE students with everything you have been through. It is such an honor to be able to work with you, as I too struggled when I was younger with many injuries! I know how it feels when you are not able to find any help in getting back to doing what you love. This is why I created FIS TV so that I can share what I have learned in order to help people like you get out of pain and take your life back! Thank you for joining and being a part of this community! I am so glad you have increased your confidence! This makes me so happy! ### 5/5 — Give Yourself the Gift of a Pain Free Body! *2023-09-14* In my 50's and 60's, I kept trying to do the same strength training workouts that I did in my 30's and 40's, only to spend more time nursing injuries than I did working out. I experimented with several different approaches to fitness and in doing so discovered Lauren Eirk and Fitness Integrated Science. After following Lauren's program, I am pain free for the first time in 20 years! My body is much more stable, balanced and mobile. Lauren genuinely cares about her clients and the free 30-minute Zoom session with Lauren is worth more than the price of the yearly subscription to the App. All of the hundreds of workouts in the program are designed by a lady who is one of the world's leading experts in body mechanics. All the videos are recorded with HDTV quality and Lauren's explanation of the exercises and how the human body moves through the ranges of motion are better than a college level course in exercise science. Give yourself the gift of a pain free body and subscribe today! **Developer response:** David, I wanted to thank you for sharing your journey with such a wonderful review! Your testimonial is such an inspiration to all of us who are 50 and up who are looking to find a way to exercise without getting an injury. We all go through so many unexpected changes in our 50s and 60s, especially with regards to our muscles. I am so gad you joined FIS TV and had the pleasure of talking with you directly online! I loved hearing your story and am even more thrilled that you have learned how to exercise in a way that does not result in joint pain! I am truly grateful for your review and even more grateful to you for your testimonial of my work! Thank you so much! ### 5/5 — Give Yourself the Gift of a Pain Free Body! *2023-09-14* In my 50's and 60's, I kept trying to do the same strength training workouts that I did in my 30's and 40's, only to spend more time nursing injuries than I did working out.

This is the only app I’ve been able to “stick with it.” My body feels better after working out w Lauren. And the results are in my injury-free tennis game, loose clothing and better posture all day long. It feels like I’ve grown two inches taller! And if you sit all day, you will looooove the many anti-sitting offerings. **Developer response:** Kathleen Thank you so much for this glowing 5-star review of FIS TV! What you are describing is the result of a healthy muscular system! When your muscles can contract better and respond better, sports injuries are kept at bay! Not only that, I love that you feel lean and confident with the gains you have made with adding more muscle to your body! I value being able to work with you so much! Grateful! ### 5/5 — Knowledge, experience and respect *2023-06-05* Awesome teacher - 5 stars!! Hands down the best thing I've ever done in my life!! It has Changed my life for good + 1 am actually learning and doing the right things for my body after injuring myself with nonsense workouts out there. I highly recommend everyone to follow her :) she is amazing! Thank you so much **Developer response:** Sonia, your review makes me so happy! I love that FIS TV has allowed you to change your life for the better, learning how to exercise without pain! The message that a lot of people hear in the world is that we need to fit ourselves into certain exercises instead of modifying exercise to fit us! It is truly a pleasure to work with you and I appreciate your kind review! ### 5/5 — Life changing!! *2023-05-10* FIS TV is truly exceptional, and it has completely transformed my fitness routine and overall wellbeing. Lauren Eirk’s focus is building strength, increasing flexibility, and reducing pain. She brings knowledge, positivity and guidance to every movement. Since starting these workouts over a year ago, I have experienced a remarkable improvement in my physical health. Before I started I was in chronic pain —in my hips and knees, and had trouble walking short distances without my lower back starting to ache. Now, I no longer need cortisone injections, dry needling, or massages to manage my pain. The first year I used the app, I could find exercises every day to address the pain and weakness I was experiencing. I am now in my second year using this app, and am stronger and in much less pain. I wake up and my mornings are no longer an ordeal. I am now able to follow the Seven Day Fitness plan, a full body plan with a recommended exercise for every day of the week. I highly recommend this app to anyone looking to improve their fitness and overall wellbeing. **Developer response:** Carlyn, Thank you so much for this amazing review! I remember when you started and I am so impressed that you have remained so consistent! You have completely transformed your body and your mindset with daily, appropriate exercise. I see you as such an inspiration not only to others who are dealing with chronic pain, but to me! I can't tell you how much it warms my spirit to see you come so far and become so incredibly strong! I am really happy that FIS TV has helped you to become confident in knowing how to manage your muscular system and keep joint pain in check! I am glad that you see the value in this program and the FIS approach! I love seeing you thrive! Thank you for writing this and it is such a gift to be able to work with you! ### 5/5 — Life saver *2023-05-10* I’m crazy about this app and Lauren! They have both been a life saver to me. When I first met Lauren I was in severe pain and literally in tears . I had been told the week before that I needed to have low back surgery asap as well as a very invasive neck surgery. I was ready because I was slowly losing my ability to walk more than a 2000 steps a day . I had always been very active so this was devastating to me. I was desperate to do anything to feel better and if that meant surgery well than so be it . I went ahead with my appointment with Lauren anyway and I’m so grateful I did . Lauren listened and offered suggestions all the while being compassionate and empathetic. She explained to me how to use the app and sent the video numbers she recommended . I stated immediately and I haven’t looked back . I have used many fitness apps in the past but Lauren’s is different. There is something for everyone and any issue you may be having . I can’t say enough about Lauren for her dedication and knowledge . Thanks to her guidance and this app I was able to avoid having major surgery and able to get my physical strength back. I was in pain 24/7 and I’m not anymore . She truly cares about her clients and is committed to helping them achieve their goals . I highly recommend this app and Lauren if you are in any type of pain or loss of function or if you are healthy and just want a good workout program. Both will change your life . I blow a kiss to her through the TV every morning when I finish my doing my video for the day . I couldn’t be more grateful! Robin Keown **Developer response:** Robin I want to thank you for telling your story and sharing your experience with FIS TV! I remember treating you with MAT when you were at your worst, and how you jumped right into doing outside work on FIS TV to reinforce what we were doing in person. I love that this app has helped you avoid surgery and take your life back! Keeping your muscles strong is the key, and now that you are more independent, I could not be more happy for you! Thank you for this amazing review and for trust in me! I am grateful to be able to work with you and witness you becoming so strong! ### 5/5 — Loving this *2023-03-14, version 8.101.1* I have done a lot of programs. I have reached the point where I was getting burnt out, or getting sore from workouts. Lauren is amazing and her knowledge of our bodies is incredible. I would highly encourage her program ### 5/5 — Best fitness app! *2023-03-02, version 7.204.1* I’ve tried all the fitness apps (I see you Peloton and Beach Body!).

And if you sit all day, you will looooove the many anti-sitting offerings. ### 5/5 — Total Lifesaver *2022-11-27* If you deal with any muscular pain this is totally the app to use. As an athlete who has been through 2 major car accidents as well as countless sports injuries I deal with a lot. There is something for every body part on this app. It’s clear Lauren thinks about the body in a different way and there are many days I could not function in life without her videos to get everything contracting. There are tons of workouts available but I tend to do more of the therapy based options. Definitely something for everyone ### 5/5 — User friendly. Thoughtful, comprehensive and extensive *2022-11-18, version 7.204.1* You will find this app to be very effective,encouraging and inspiring! Lauren offers numerous variations and modifications in her videos making this a fun,challenging and very rewarding app! ## Most critical reviews (10 lowest-rated) ### 5/5 — L M *2026-01-03* FIS TV progressive programs from Isometric to load bearing exercises have helped me have the strength and agility to move and accomplish daily tasks at work as a nurse and as a grandmother. Lauren’s instructional videos have helped me address neck, back and overall joint pain as they arise. Learning to activate the muscles and looking at the whole body is essential when one area feels off line. Thank you for a massive platform to help keep my body healthy and functional. ### 5/5 — User friendly.

This app is amazing! *2025-06-17, version 9.100.1* This is an Phenomenal app…Lauren gives amazing cues and the equipment she recommends are high quality and very reasonably priced. You really don’t have to have the equipment and can use substitute things we all have at our homes! I really enjoy the BOOST workouts along with the variety of isometrics/Integrated Isometrics and Calisthenics AND the options for Yoga and Pilates! All in all… Content, Quality of Instruction along with the effectiveness of EACH work out… it is a bargain!!! Try it and see.. you will NOT be disappointed! ### 5/5 — Organized and easy to find what you need *2025-06-05* This app has just what I’m looking for to get back into fitness.

Grateful! ### 5/5 — What a blessing to have found this!!! *2025-02-01* Nothing like it! You will never find another app that you can use for fitness and rehabilitation for ANY injury or pain you have. Too many people just want a pill to make them feel better in their body BUT you actually need to move properly and functionally. Lauren Eirk is the most forward thinking fitness expert I’ve ever met and trained with. She really cares about what she’s teaching to truly help people. She is not just putting out click bait. Everything she says and does is backed by research and science and years of experience. What a blessing that she is sharing all of her knowledge. The app is easy to maneuver. I usually just type in the search bar to find a workout that addresses any pain I’m having that day. I’ll type “hip pain” or “shoulder pain” or “sciatica” and dozens of videos pop up to choose from that addresses those specific issues. Then I can decide how much time I have and choose one that fits my schedule: from 15 to 30 mins or 45 mins to an hour. You never have an excuse not to do SOMETHING. If you are finally fed up with always dealing with pain, then you need this app. ### 5/5 — Best fitness app! *2024-12-10* I’ve tried all the fitness apps (I see you Peloton and Beach Body!).

It’s been a huge help and a great resource. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/). User reviews are verbatim App Store reviews.
