Lay flat on your back with knees bent hips distance and put one foot in the air, drive the opposite leg down through the heel to push the hips. 15 of these on each side and your booty is well on its way for teeny bikinis this summer.
Great booty exercise! Lay flat on your back with feet on the ball.
Ab roll-outs are a great core exercise.
After roll-outs, plank with feet on the ball and pull your knees to your right elbow, then back to plank. Then to the right elbow.
Advanced; Plank to pike with the hips.
An easier version, but also EXTREMELY worth the effort. Do this one with the plank, maybe alternate the 2 movements.
