Lie on your back wiith knees bent and feet flat. Bring your right knee up to your chest, placing both hands on top of leg, just above the knee. As you push down on your leg, resist the downward force by contracting your hip flexor muscles. Once the heel of your foot taps the mat, bring that knee back up to your chest again, pushing against your hands' resistance. Do 10-15 slow repetitions and repeat on your left leg.
Tip: Make sure to keep your neck relaxed and your lower back flat against the mat throughout this movement.
