Bored with hit the floor and give me 20? FitSugar suggests you spice it up by adding the Superman move before the grrr back up. Fly first, then push up.

A Superman push-up will have you stretching and strengthening your back and engaging your core -- before your tummy ever goes airborne. This video makes them look fairly easy, perhaps it's the music?

Get stronger than a locomotive and start out with 20 or count how many you can complete in a single minute.

Weight loss stalled? Kick your speed in gear and start interval training -- that's when you do an exercise at high intensity for a short period of time, followed by low intensity exercise for the same period of time.
