Hip Circles
Hip circles are a simple mobility exercise in which the hips are moved in a circular motion to improve flexibility and range of motion in the hip area. This exercise activates the muscles of the lower back, hips, and abs, and helps to distribute joint fluid, leading to better hip mobility and injury prevention.
Hip circles are ideal as a warm-up exercise before physical activities or as part of a mobility routine, as they gently guide the hip joints through their full range of motion.
