There are never enough hours in the day to do everything you want — and that especially applies to working out right. But even if you’re in a rush and don’t have a lot of space, that’s no reason to take a rest day.
“This is a great little workout you can do to burn out your upper body,” Marthaler says. “You’re going to do as many rounds of this as possible in that 20 minutes.”
You’ll be doing pyramiding down-sets of sit-ups and push-ups. Do 11 sit-ups, 11 push-ups, then 10 sit-ups, 10 push-ups, and on and on until you get to one. Take a 30-second break, and try it again.
It’s a lot to handle, so let Marthaler take you through proper sit-up technique: “Keep that chest up,” he says, “abs tight, and slowly peel off and come up. Keep those abs nice and tight—when you’re up [at the top of the sit-up] you don’t want to relax them. And roll back down.”
Equally important is push-up technique: “I want a 90-degree angle on your arms,” Marthaler says. “I want your body completely in-line with the ground, a nice solid board. Abs are tight, butt is tight.”
It’s short, simple, and extremely hard. Do as many rounds as you can in 20 minutes—we bet you don’t make it to four.
