Do a full-body workout with resistance bands.

“I used a thin, long-looped resistance band, cranked up the music, and put this workout to the test. [...] Reppel has cleverly programmed her workout to be as effective as possible in a short timeframe, achieved by working you for almost the entire minute with little rest between exercises (10 seconds of rest begins to feel like one second pretty quickly). But most importantly, everything is functional and focuses on improving your ability to perform everyday movements like squatting, pulling, or how to do a push-up. My shoulders were on fire within a few minutes; Reppel seemingly takes inspiration from Pilates-esque techniques, repeating small motions (for example, shoulder shrugs) for high reps against your band to build intensity. You don’t need to go heavy to feel the effects, either. Combining a plank with a single-arm row (despite sending me into sweat mode) helped challenge my core balance and keep me on my toes – literally.”

“I see more progress with TapouT XT (old program from 2012) than anything else I've ever done, in a short amount of time. It uses bands. But it's nonstop full body workouts for 45 minutes where there's a new exercise every 30 seconds to a minute and you switch from bands to floor, bands to floor. So it's intense and fast-paced. I'm toast by the end. More so than any workout I've ever done with a trainer or on my own in a gym or on any piece of equipment. And the gains are fast.”
