#1 Step 1: Deadlift
Why it works: it engages and strengthens the muscles in your back, glutes, and hamstrings.
Stand with arms across your chest, feet shoulder-width apart, knees slightly bent, maintaining a straight line through your spine.
Bend at your hips, bringing your chest toward the floor. Keep your eyes focused downward. Keep your neck in line with your spine. Keep your back flat as you slowly bend back up.
Repeat 3 sets of 15.
