The 10-Minute Transformation
Don’t let this bodyweight workout fool you: “You won’t lift a single weight, but in just 10 minutes you'll work harder and sweat more than most guys do in a half hour,” says Gaddour.
Every second is a lung-busting, sweat-pouring challenge. No time wasted, no room for excuses.
HOW TO DO IT: Perform each exercise for up to 60 seconds (stop if you lose good form), moving from one to the next without rest.
You can use this 10-minute circuit anytime for a quick metabolism boost, or do back-to-back circuits to create a 20, 30, or 40-minute workout. Rest 30 to 60 seconds between circuits.
