To do a straddle stretch, sit on the ground or a mat with legs apart in a straddle position. The width of the straddle is up to you—whatever feels comfortable and a little challenging, without causing any pain.
Once you are seated, bend slowly over the right leg, then to the center, then over the left leg. Hold each position for at least 10 to 30 seconds, without bouncing. These stretches work the lower back, sides, inner thighs, and hamstrings (the large muscles on the back of the thighs).
