Working muscles: Chest, core, biceps, triceps and back.
Progression: In a plank position, with the hands planted two to three feet apart under the chest line, bend elbows and descend down for two counts until the chest nearly touches the ground. Rise back to plank position for two counts. Repeat 10 to 12 times.
“Push-ups are great for the upper body,” Schatzle says. “You can do them anywhere.”
Extra credit: Slow down the push-up. “By descending at a slower rate your muscles fire up more,” Schatzle says.
