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

This is one of my must- have sources for referring back to. Diagrams, constant improvements, thorough information. So good.However, with the new updates, I noticed a few exercises were listed as a compound when it’s an isolation exercise (example: concentration curls for biceps) and vice versa. Other than that,it’s great.
