We'll wager a guess that your go-to bodyweight routine — the one you employ at the park, in front of the TV, and in hotel rooms — is stale. You can only get so psyched to do the same lunges, squats, and push-ups. Which is exactly why celebrity trainer Anna Kaiser created this total-body workout. "I wanted to challenge people, get them out of their comfort zones and more connected to the exercises they're doing," says Kaiser, who uses the moves in the explosive strength-and-cardio classes at her New York City studio AKT. "If the move feels new, you'll be more engaged, push harder, and find it more fun than doing the push-ups and burpees you've done forever."
But fun doesn't mean easy. Perform these six moves correctly, and you'll be winded and shaky by the end — a nice reminder that you're not just strengthening every muscle, you're getting in cardio too. Do the six moves in order, taking no breaks between exercises, then rest one minute. Do three rounds total.
