A gymnastics exercise to work the glutes.
Lie down with your arms along your body and your palms facing down. Your knees should be bent and your feet fixed on the floor.
As you exhale, push your buttocks up until it forms one line with your body.
Pause for 2-3 seconds at the top.
As you inhale, return to the starting position without touching the floor.
Feel the stretch in the glutes every time you reach the top.
If this exercise is too easy, put one leg bent at the knee on the other. Or put both legs on the support, for example, on a bench.
