every day for a week, do more star-jumps (aka jumping jacks) within a minute than the day before
there’s more than one kind of star-jump! This challenge includes the following:
half star-jumps (both arms go up while stepping wide with alternating feet)
classic star-jumps (jump the feet wide and narrow, mirroring the feet with the arms)
clap star-jumps (perform a classic star jump, but clap the hands at the top of the jump)
x-jumps (both feet leave the floor in the wide position)
the rules:
1. perform as many of each type of star-jump within a minute as you can
2. every day for a week, perform more in each category than you did the day before
3. if you don’t make it … start again!
4. record your maximum star-jumps in each position daily
