This exercise will focus on the gluteus maximus. This muscle is the main muscle that pushes your hips or extends your hips during walking and running.
Start off standing, with your feet together. Your body should be square. Keep both legs straight.
Gently kick one leg straight backwards, still keeping it straight.
Kick backwards, hold it there for a couple of seconds, and slowly bring back down to the ground.
To properly perform this exercise, you should squeeze your buttocks and maintain the engaged muscle throughout the exercise. The muscle contraction will create a blocking so you don’t incorporate and overextend your lower back.
Do this exercise 20 times on each leg, a couple of times each day.
