Holding ring lower and lower

Use a gymnastics hoop for this exercise. Start by holding it at the water's surface so the child can glide through it. Gradually lower the hoop, encouraging the child to glide through it like a "submarine" along the pool's bottom. This exercise increases the difficulty as the child learns to push off at the lowest point of the pool and maintain that depth. Proper body posture influences the swimming direction, and the variation in diving depths makes the exercise more effective.
