How to do it: “Place a resistance band around your ankles. Make sure to choose the appropriate resistance for your fitness level. Performbetter.com sells the bands in green (the easiest), yellow, blue, and black (the most resistance). Grab a pair of three-pound dumbbells.

Simultaneously press the dumbbells up as you jump your feet out. Try to continue for 30 seconds.”
