2 ways to shape your buttocks
1. Kick your legs back. Kneel with one leg on the mat and place the other leg on the rack behind you. Use your hips to kick your legs back. Then retract the legs and stop them in front of the chest. Repeat 8 to 15 times and then switch legs for a total of three sets.
2. Hip lifting exercise. Lie on the ground, put your arms on the ground, and lift one leg up to make it in line with your body. Exhale and lift your legs slightly upward, maintaining it at 90 degrees, and then return to the original position. Repeat 8-15 times, then switch legs and do 3 sets in total.
