Think you can count in your head and that's enough? Think again. You will quickly realize that this app is your missing gym tool.  Build muscle faster with TrainCentric, the #1 tempo (time under tension) training app. It allows you to fully customize exercises and workouts with adjustable muscle contraction tempos, reps, sets, and rest. The majority of the people lifting weights neglect to put emphasis on each movement and instead try and lift the heaviest weight that they can. When using TrainCentric you may have to lower the weight you're using, but we can guarantee you'll feel the burn more than when using heavier weights. Building muscle is a complex process with many important variables, and TrainCentric creates consistency across your workouts by keeping more of those variables constant. The app will provide you with a standardized tempo for each rep, allowing you to focus on activating the muscle rather than counting reps or tempos. By letting TrainCentric take care of the counting, you can focus on controlling the weight and ensuring you are getting the most out of each rep and set. TrainCentric will transform your current workouts by simply increasing the time under tension and putting more emphasis on each of your muscle contractions.

I use for doing custom at-home physio exercises but I could see using it in a gym as well (you might need earbuds depending on noise level). There are also a range of standard exercises to choose from with built-in time suggestions — all of which can be modified. Very helpful! ### 4/5 — Neglected ? *2024-03-06, version 4.2.8* Has this app been neglected? ### 5/5 — Game changer *2023-11-30, version 4.2.8* Even though this app hasn’t been updated in 3 years (I believe they are revamping the app for private healthcare usage) this app has changed my relationship to training! The prompts are so good, it’s very intuitive as you can customise exercises to no end as well as including AMRAP sets. The choice of verbal countdown, contraction clicks, adding reps and inclusion of tempo is awesome. It would be great to be able to record when a set isn’t completed because it happens sometimes in training! It’s only 4 stars instead of 5 because creating custom exercises has a bug of not confirming creation. I love this app and gym bros ask me what I’m using after seeing my form and my phone animation lol ### 5/5 — Best tempo training apps ever found *2023-06-21, version 4.2.8* Title tell all!! This is simply the best apps for tempo training. Try by yourself! ### 5/5 — Update your Android version , it’s time *2023-01-09, version 4.2.8* It’ ### 5/5 — Best Time Under Tension for The Gym, Rehab, and Dynamic Stretching *2022-09-17, version 4.2.8* This app does exactly watch it says it does with and you can use the verbal commands to do the concentric et eccentric. I’ve used it for years with no issues. It offers lots of options to creating your tempo. Their support team is excellent if you ever need help or have an issue. Thank you so much for creating this app. My hope continue to add new features and even more options while keeping the basics of what has worked with this app for years. ### 5/5 — amazing app!! *2022-09-02, version 4.2.8* this is such a helpful, effective, intuitive fitness app!! thank you so much for creating a quality free app so EVERYONE can train effectively! ### 4/5 — Add ATG exercises, SaltWrap.com, Becoming A Supple Leopard, and Free+Style exercises from the book. *2022-07-08, version 4.2.8* This app is a phenomenal app. I didn’t realize how important slow tempo exercises are for the rehabilitation of the muscles. The user interface is super clean and intuitive. I wanted to give a 5 star, but I wanted to get the attention of the developers. An awesome addition would be to add the exercises from Ben Patrick’s ATG system, Scott Hogan’s Built from Broken book, Kelly Starett’s Becoming a Supple Leopard book, and Carl Paoli’s Free+Style book. In addition, you should add general mobility exercises that effective. I recognize you don’t want to clutter the different categories with random exercises, so you could add a portal for the extra exercises and call it mobility. I haven’t used the HIIT section yet, but I’m mostly gonna switch over from the other app I use. ## Frequently asked questions about TrainCentric ### What is tempo training?

This app helps you implement specific tempos for each exercise to maximize muscle engagement and growth. ### How does this app help build muscle? By emphasizing time under tension and providing standardized tempos for each rep, the app ensures you focus on muscle activation rather than just lifting heavy weight. This controlled approach can lead to greater muscle stimulation, faster growth, and better retention. ### What kind of workouts can I create? You can create fully customized workouts with adjustable muscle contraction tempos, reps, sets, and rest periods. The app also offers unique HIIT training and supports strength, hypertrophy, and HIIT programming. ### Is this app compatible with my device? While specific compatibility details are not provided, this app is designed for mobile devices. Users should ensure their device meets the minimum operating system requirements for the app to function correctly. ### What are the costs associated with this app?
