A BOSU ball is basically an inflated dome that resembles half of a stability ball. If you have access to one at your house or at the gym, you can do this full-body routine from NASM-certified personal trainer Sydney Cummings. Moves include plank jacks, single-leg toe touches, and sit-up and jump, and you'll also need a set of dumbbells briefly.
