Build strength with guided workout plans, gym routines, and in-depth biomechanics. Muscle & Motion brings training to life with 3D visuals that show how your body moves.
The Strength Training app is powered by a team of physiotherapists, movement experts, and professional animators. We turn your device into a visual strength-training lab and show you exactly which muscle structures are working, so you can understand the anatomy and biomechanics of the exercise, and train smarter while reducing injury risk.
Made for personal trainers, strength coaches, therapists, students, and dedicated lifters, this app connects what you feel in the gym with what’s really happening in the body.
Designed for visual learners
If you learn best by seeing, this app is made for you.
Why trainers, coaches & students love it
- Makes complex anatomy easy to understand through clear 3D animations
- Shows exactly which muscles and joints are involved in each exercise
- Reveals common mistakes so you can coach better form
- Explains concepts far better than static images or textbooks
Backed by thousands of 5-star ratings and trusted by movement professionals worldwide.
Instead of static diagrams, you get animated 3D views of real lifts: muscles slide, shorten and lengthen as the movement happens, making it much easier to remember which structures are doing what, and why it matters

It’s surprisingly intuitive of how our body moves. We usually do not do move our body to the full extent while doing any exercise. for example while doing leg and hand raises with weights. In here the animation of the muscles turning RED in colour is indicated only when the move in done to the full extent. This is very helpful in understanding how to do exercises correctly

Thank you for taking the time to rate our app!!
Content is great but app functionality is unresponsive and buggy
Uttej Shas
I wish I could give 5 stars for the app content alone but due to its lack of responsiveness, content loading, forever buffering wheel though my internet speed was good and all other slow to death of this, I’m giving only 2 stars.No doubt, it is one of the best in terms of content and information but I feel if they can design a standalone app rather than fetching everything from a web instead of making native, then there is surely no point of investing their efforts in mobile apps. Dear Developers, kindly note of it and provide the update with native like features with better loading times.
Great App
Dave Naorem
The moment I came across this app I went through the reviews and thought of giving it a try . Trust me it was worth trying and have already enrolled myself. The way exercises are shown and explained it is very easy for anyone to grasp. Good job guys keep it up and keep on adding new movements and exercises...
