Jillian Michaels didn't get her toned arms and chiseled abs overnight. The trainer, who earned a reputation as America's toughest trainer on The Biggest Loser, puts in work at the gym. Since she's known to take everything up a notch, it's no surprise that she grabbed a pair of kettlebells and created what she calls a "challenge circuit." "Challenge" may be an understatement.
Jillian did a mix of push-ups on the kettlebells, hop-throughs, L-sits on the kettlebells with single-leg kicks, and even grabbed a foam roller for ab pikes with a push-up. This whole routine has our abs sore just looking at it!
If this circuit is too advanced for you (*raises hand*), try one of the free daily seven-minute workouts Jillian has on her app, My Fitness by Jillian Michaels. You don't have to be an expert in the gym to get in a good sweat; Jillian just wants people to start moving and take it slowly at first. Before long, you will build up your endurance and can challenge yourself to take on more advanced moves.
In the meantime, we'll stick to her three tenets of burning more calories at the gym: metabolic circuit training, compound movements, and HIIT.
