Only do the position that you feel you can handle.  Make sure your surrounding area is safe.  Have cushioning under your knees when doing the push-up exercises and behind you when doing the back exercises.

Reps can be between 5 and 20 (a rep is one complete movement)

Sets can be 1 to 3 (a set is a number of reps)

Progression can be a change in body position and the number of sets and reps.

Make sure you’re breathing!

Usually there’s at least three people involved so I’m still working on lighting, etc.

Keep Happy, Healthy, Safe, and Sane!
