[Supine butt lift] mainly exercises the buttocks.
Lie on your back on the mat, with your legs bent, your hands on your sides, and your feet flat on the mat.
Press your heels, slowly raise your hips, and then slowly lower them to the starting position. The lifting height can be gradually increased.
If you need to increase the difficulty, you can practice with one foot on the ground. Do 4 sets of 20 times every other day.
