In a squat position with ball held at ankles, slowly raise the ball to a sticking point, approximately shoulder height, then start hip motion slowly pushing down to straighten hips and with shoulders pulling the ball overhead. The ball may be started from behind at ankles and raised to waist height as hips rise. Also, stretch cords may be looped one on each thigh and anchored at the center to give added resistance to the hip extensors during the rise.
Duck walks focus on the hips and work well with the strength training done with the lunge and squat.
Take care to land under control and immediately spring back over. Squat jump over a hurdle while holding a D-Ball. Use a series of hurdles and boxes for multiple jumps. Lunge over the hurdles with or without a ball. Use a Balance Board for squats and Balance Beam for walking lunges.
