I would love to know the answer to that too

Ok, i'm an at home exercise freak, and I love to make up my own workouts. What really works for me are pelvic thrusts. I don't know if you know what they are, but here i'll explain anyway. Lie on your back with your knees bent, and your hands on the floor beside you, palms facing down. Then using your arms and legs, lift you but of the ground, and squeeze your butt muscles as you come up. Hold for like a count of three, and then return to your starting position slowly. Do like 3 sets of 20, you'll be feeling that in the morning. Good luck, let me know if it works. :d

Also you could always do squats, to make that more challenging hold weights while you are squatting. *remember do not let your knees go over your toes, it will cause injury. Like ashy said, do your exercises slowly, the slower, the better workout you will get. Try and count for at least 3 seconds going down and at least 4 coming back up!! Good luck!
