Excellent Form Tutorial Videos

As someone who is new to the gym, the form tutorial videos are super helpful and straightforward with none of the added bs that a Youtube tutorial videos would show.

Great app!

CalmArms is a great app and very easy to use! As someone who’s always been active but never had access to a personal trainer, I never realized how much my form was holding me back. This tool closes the gap between working out and working out correctly. Highly recommend.
