The advantage of breaststroke prone position is that it can stretch the muscles and ligaments on the inner thigh, correct the O-leg and X-leg, shape the perfect leg shape, and lay the foundation for crotch opening, so it won't hurt too much when opening the leg. If the frog is not prepared before lying down, it will cause muscle and ligament strain.

Frog squat should be done step by step, with standard movements and gradually increased efforts. Sticking to crouching 10 minutes every day and practicing for 20 days will have a good effect. At this time, if you do hip-stepping exercise, it is easy to split your hips.
