Great timing with this! My workplace does a charity pushup challenge every year, and I usually create a team for people looking for alternative exercises. I was considering yoga for this year and was just looking for resources to help provide daily customised sessions. 1 minute of yoga/stretching = 3 pushups or something like that.

This will really help fill the gaps, and I'll probably recommend it to people doing the regular pushup challenge for warmups and healthier workouts.
