About this app

“Stronger at 58 than I was at 27” -Bob McDermott. If you're looking for a workout routine to build muscle, muscle fitness and strength, we have something even better for you. This app gets you in shape fast using artificial intelligence. It's 59% faster, evidence-based, and always up to date.

Expert reviews:
"It makes working out very simple. All you do is answer a few questions about your unique situation and your goals, and then it generates a workout program for you. Then, when you do the workouts, you enter in your weights and it tells you how much weight and reps to do each and every workout, and it's based on the latest science of DUP."
— Jason Maxwell - Aerospace Engineer and fitness and nutrition author

"It's already a good design and has great workouts that will help you continually build muscle and break through plateaus, but they are constantly working to improve it based on customer feedback. The most important thing about this app is the customer service. Christelle and Carl are always available to assist you in anyway they can in a very timely manner, most of the time within an hour of submitting your question or issue. I would recommend this app to everyone serious about building muscle."
— David Fechter


A PERSONAL INVITATION
Hi, I'm Dr. Carl Juneau. 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 or gym trainer 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.

I was trying to edit previous review and accidentally deleted: used to love this app, but now it's completely unusable as a workout tracker unless you pay (if you go into a specific exercise to track your sets for it, an ad with purchasing options for the premium "Autopilot" version pops up and cannot be closed. clearing cache, refreshing the app, none of it gets rid of it. This has been a long time problem that was seemingly resolved for a few weeks and now is back again.

This app is the best. Truth in advertising! Customer service responds in 24 hours or less, and the app stays free after the 14-day trial. Downers, I needed either a 30-day trial or more in-app instructions. Also, I have yet to purchase a subscription, so every time I click to complete an exercise, a pop-up asks me to purchase. This really interferes with and frustrates my usage of this app and is my reason for giving 4 out of 5 stars. I don't like nagging. Reminders are fine.

Hi Tanz. Thanks for your sharp feedback. Your points are well taken. We're changing that popup to show just once per workout as we speak. Please reach out to us at support@drmuscleapp.com. We'd like to make sure that's to your liking now. Stay strong!

TLDR: I FREAKING love it, 6 other workout apps did not even come close to this one! The biggest issue I faced is the lack of motivation, and I now went consistently for a month straight. I never did this before.. The app is backed with science, you don't have to think about weight amount, reps, pauses, what workouts to do, how often to train. I always wanted to follow a precise system from a pro and I finally found it. I really believe this app needs to get more love than it currently receives.
