Benefits: Tones hamstrings and buttocks.
Ready: Lie on your back with your knees bent. Cross one leg over your thigh.
Go: Raise your hips until in line with your torso, squeeze your butt at the top, and then slowly lower hips to the ground. When you can do 2 sets of 10 reps, try moving the foot on the ground much father away from your butt; this works the hamstrings more as you raise your hips.
Challenge: Have your toddler straddle your hips. If your hips don't stay level as you raise and lower, your child will tilt to the side where the hip is sinking. This is a great way to check that you are performing the exercise correctly and in balance.
