This Summer Butt Challenge is designed to tighten, tone, lift, and reshape your butt. You might ask: Is this challenge easy? No. Will I be sore? Probably. Will it be worth it? Definitely. How much time will I have to dedicate each day? 20 minutes or less.

What you’ll need for this challenge: Water, a yoga mat, a flat bench, kitchen chair, or stable box about 2′ from the floor, one light set of dumbbells (3-5 lbs), an interval timer, and ankle weights (optional).
