Correct Speed for the Apps

In gyms and on television it’s common to see people doing their reps very fast. This looks great, but performing the exercises slower and in a controlled manner is much harder (and thus better for you).

To help you do them slowly, the app will warn you if you are going too fast.

NOTE: sometimes the app can get confused when your motion is too fast or too jerky. If this happens it may say "Half".

A slower speed is better
