Squats are excellent for slim thighs, a tight butt, and sculpted hamstrings. By adding the press, the core and shoulders are engaged the entire time.
How to do it: Grab a set of dumbbells and stand with your feet hip-width apart. Bend your elbows and bring the weights to shoulder height. Lower down into a squat by shifting hips back, like you are sitting in a chair. Come back to standing and press weights directly overhead. Lower the weights back to shoulder height as you immediately lower into your next squat. Continue the movement at a quick pace for 10 reps.
