This strategic, super-effective form of high-intensity circuit training is supported by science. To complement the originaland give you even more 7-minute options, we asked Yusuf Jeffers, certified personal trainer and Head Coach at Tone House in New York City, to create a companion abs workout that requires only your body weight.

A killer combo of core-strengthening moves and cardio, this circuits designed to attack not only your abs and obliques, but also the muscles in your back, pelvic floor, and even your shoulders, says Jeffers. And, truth be told, it beats doing hundreds of crunches. If youre training for a sportor just for everyday lifeyou usually dont use any one muscle in isolation, he says. This correlates closer to actual, functional movements. And thats a good thing: While crunches certainly strengthen your abs, the body benefits moreby torching more calories, for examplefrom movements that recruit more than one muscle group.

Though its important to remember that high-intensity interval training isnt meant to be a daily workout, its a great tool to have in your exercise arsenal, particularly on days when all youve got is 7 minutes to spare.

How to use this list: Perform each move below for 30 seconds, resting 5 to 10 seconds in-between. With this circuit, the goal is to go big or go homemeaning, working at the highest possible intensity for as many reps as you can without sacrificing form. Expect to perform anywhere from 15 to 20 reps, though remember that quality always tops quantity, says Jeffers. (So dont stress if your rep count is on the lower end the first couple of times you try thistheres always time to improve.) If time allows, you can repeat the circuit 2 to 3 times.
