Forward Lunge

A lunge will work your abs, your back, hamstrings, quadriceps, and your hip flexors all in one movement. Not only is this a great movement to incorporate in your warm-up routine, as it helps to initiate and increase blood flow to our major muscle groups (glutes, hamstrings, quads) and stretches the hip flexor, a muscle that is often tight due to our increasingly sedentary lifestyles.
