Basic Training: Torch 225 Calories in 25 Minutes
Kick it old-school and get firm in a flash with this calisthenics-based bodyweight workout
If you haven't done calisthenics since phys ed, it's time you kick it old-school again.
"Performing bodyweight moves at a quick pace improves your endurance while increasing your strength, range of motion, and balance," says Jay Cardiello, Shape's fitness editor-at-large, who designed this plan.
You'll do two rounds of 10 exercises-dividing up your workout makes it easier to maintain a high intensity-cranking out as many reps as you can of each move in the time given. (Not sure how to do the walk out pushup? Click here for a demonstration and get ready to sculpt those abs and arms!)
