Lie on your back with knees drawn toward your chest and arms wrapped around your shins. Gently pull your knees in while keeping your lower back relaxed against the floor to stretch the hips and lower back. Hold the position and breathe deeply to release tension and improve mobility through the hips and lumbar spine.
Log your lying leg tuck hip back stretch sets in 1RM.fit and watch your estimated 1RM update automatically as you get stronger.
