Bodyweight Good Mornings – 3 sets x 12 reps, 20 sec rest
Starting Position: Stand with feet shoulder-width apart, hands behind your head, and your elbows out.
Execution: Hinge at the hips by pushing your butt back, keeping your back flat, and lowering your torso until it's nearly parallel to the ground. Return to standing by engaging your hamstrings and glutes.
Muscles Worked: Hamstrings, glutes, lower back.
Form Tips: Maintain a neutral spine, and ensure the movement comes from the hips, not the lower back.
