Your program in a few taps
Excellent training app! Musku is smooth, simple to use and really handy for tracking my workouts day to day. I love how motivating it is, the clean interface, and how easy it is to build your own training plans.
Finally an app that motivates me
Finally a lifting app that makes you want to get started! The interface is super clear, you log a session in two seconds, and the progress charts are so satisfying to look at. Highly recommend!
Efficient and simple
Very handy app for organising and tracking your lifting sessions. You can build your own programs easily. There is a huge number of exercises available, and it is simple and intuitive to pick up.
Excellent app
Really good app, very intuitive. If you are after something complete with a nice design, go for it, you will not be disappointed.
