Sit with your feet flat and knees slightly bent. Hinge forward at the hips, reaching your arms toward the floor or your feet, and let your chest drop toward your thighs. Keep your back long and neck relaxed as you feel a controlled stretch through your upper and mid-back muscles. Breathe deeply and hold to release tension and improve spinal mobility.
Log your sitting bent over back stretch back sets in 1RM.fit and watch your estimated 1RM update automatically as you get stronger.
