Stand upright with your feet about hip-width apart. Raise one arm overhead and gently lean your torso to the opposite side until you feel a comfortable stretch along the side of your body. Hold briefly, then return to the center and repeat on the other side. Keep your movements controlled and breathe steadily to deepen the stretch without strain.
Log your standing lateral stretch sets in 1RM.fit and watch your estimated 1RM update automatically as you get stronger.
