[Bend control action] can exercise the calf muscles and improve the flexibility of the legs.

First, spread your feet apart, straighten your legs, put your hands naturally on your hips, straighten your back, bend forward from the hip joint, and maintain this posture for counting from 1 to 15.

Then bend further, grab the calves with both hands, keep the legs straight, do not hug the knees tightly, and do not try to touch the ground. Keep this position for 30 seconds and count from 1 to 10.
