In 2009, I got really sick and lost all my muscle mass. As a trainer, that was rough. Let's just say clients didn't really trust me, even with a PhD. I just didn't look the part. I finally gained back 27.7 lbs of muscle, but that was tough. I kept failing. Now, I'm squeezing all I learned into this app. It's an intelligent, virtual coach that takes the guesswork out of training and gets you in shape fast. With your smart coach, every time you complete a set, your program updates automatically to match your progress, and speed up future progress. It gets you in shape fast, like a personal trainer. But it's 59% faster, evidence-based, and always up to date. It automates almost everything, and guides you through the entire process. It's designed to make training a rewarding experience, simple, and fun again. DR.

I’ve seen apps that are overly simplistic and don’t do much more than a spreadsheet or ones that try to be so fancy that it feels like every workout is a science project. Dr. Muscle, as an algorithm actually seems to do what it claims. Workouts make sense, progression keeps ticking up, feels like the right amount of challenge. Too bad the app is brutal. It gets confused about which workout it’s on if you try to change an individual workout, it crashes periodically, sometimes I choose a workout while travelling it shows it to me but when I complete it, it doesn’t keep a record and immediately cuts to the previous workout. If I leave the app to do something for work (it comes up) for a few minutes I get kicked out of the workout and if it is a one-off workout it’s a bizarre series of button presses to get back to it. In all, more trouble than it’s worth and for a very premium price. ### 2/5 — Can be frustrating *2025-11-27, version 3.2511.1710* Could be good, but instead its wastes your time with a lot of questions that slows you down. There’s no way to disable them. And it doesn’t seem to remember what you’ve done consistently. The chat function has extremely limited capability. ### 3/5 — Ai and micro nutrition *2025-11-21, version 3.2511.1710* The app is great except it feels like the ai doesn’t remember what was said before that message and is either too stubborn or too vague to help you change something ### 1/5 — App crashes constantly *2025-11-17, version 3.2510.2524* Would love to give this app a try, but it won’t ever open. It crashes every time I try and use it. ### 1/5 — Not working *2025-11-17, version 3.2510.2524* The app just not opening. I restarted my phone, re installed the app, but still not able to open it ### 1/5 — App stopped working *2025-11-16, version 3.2510.2524* App has stopped working. Won’t load. ### 1/5 — Broken *2025-11-11, version 3.2510.2524* App no longer opens? ### 5/5 — Great app *2025-11-07* The best app for your workout and diet program ### 1/5 — Worthless *2025-10-24, version 3.2509.2618* App was initially great. However it then lost all of my history and data. There is ZERO customer support - just some AI bot. They didn’t offer any reasonable refund for the 2 months of bringing the weights in the app back up to speed. AVOID this app- if they had a reasonable customer service team I would re consider. But for now, trash. UPDATE: They continued to not offer meaningful solutions but kept asking me to perform fixes which didn’t work. They refused to troubleshoot over the phone- leading to the multiple emails as they described. I’ve cancelled my subscription and would recommend finding another app with less bugs and primarily better customer support. ### 5/5 — Best trainer I’ve ever had *2025-10-01* I started lifting at 18 and am now 59. Training is my job, my passion and my life long love. I occasionally get bored doing my own thing and want something to push me. I recently searched “best training app” on chatGPT and Dr. muscle came up. I have tried other platforms in the past but quit within a month because they are a waste of my time. Your app changed the game! I LOVE IT!! I’m lifting more than I thought I could and love the progressive programming and feedback the app provides. It is worth every penny! Don’t stall on this - try it out! ## Frequently asked questions about Dr. Muscle AI Personal Trainer ### What does Dr. Muscle AI Personal Trainer do?
