Lower body: Slow mo squat

*More challenging

Stand with feet hip-distance apart, a 5-to-8-pound dumbbell in each hand, and arms by your sides. Squat down until the dumbbells touch the floor, pushing your butt back and keeping knees behind your toes. With abs tight, shoulders back, and butt muscles engaged, slowly begin to rise back up, inch by inch (as shown), until you reach standing position. Then slowly lower back down, inch by inch. Do 10 reps.
