Standing Forward Bend is a bodyweight exercise that primarily targets the hamstrings, lower back, and calves. This is an excellent exercise for improving flexibility and range of motion in the posterior chain. By hinging at the hips and reaching down towards your toes, you can get a deep stretch that can help with muscle recovery and alleviate tightness.
Stand upright with your feet hip width apart.
Bend at your hips and torso and reach your fingers towards the outside of your feet until you feel a comfortable stretch in the back of your thighs.
