Butt exercise: Targets gluteus maximus and hamstrings. Lie facedown on floor with head on folded arms, squeezing a 1-pound dumbbell or rolled-up towel behind bent left knee, foot flexed. Tuck pelvis to flatten out low back. Lift bent left leg a few inches off floor; lower. Do 20 reps. Switch sides, repeat
The best way to learn how to squat correctly is to do squats facing a wall. Bring your toes to the wall, almost touching, then sit down. Stay looking straight so you learn to keep your torso up. Sit as low as you can go then hold the seated position for 5-10 seconds and repeat. Great for butt, legs, and core.
