When Jillian Michaels puts in work at the gym, she's usually showing off her abs in a sports bra or crop top. Now, the fitness expert, who has her own workout app called My Fitness by Jillian Michaels, showed us how she gets her strong core and sculpted abs with a challenging circuit on her Instagram page.
The former The Biggest Loser trainer shared a core circuit that included four moves. Since some of the moves required a dumbbell and a pull-up bar, this is probably best performed at the gym. Jillian said to do 30 seconds per move and perform the circuit four times through. Although she doesn't indicate a rest time, try to rest no more than one to two minutes in between each circuit.
Although this workout is less than 15 minutes total, you will definitely feel the burn. These exercises work your whole core, which isn't just for vanity; core strength is important for helping with back pain, improving posture, and preventing everyday injury. Grab a dumbbell and get to work!
