If you're in need of some major fitness inspo, you've got to follow personal trainer and creator of the PWR program Kelsey Wells. The PWR program is one of the four programs from Kayla Itsines's SWEAT app, and it's all about weightlifting and building lean muscle mass.
If you're not ready to commit to the $20 SWEAT app subscription, Kelsey has been sharing snippets of the program on her Instagram. One of our favorite workouts she's shared thus far is this four-move ab workout. According to Kelsey, the workout is "a quick abs sesh you can do anywhere you've got a bench."
If you don't have access to a bench, or find that doing these exercises on a bench is too advanced, try doing the moves on the ground. Continue reading for instructions on how to do each exercise and the ground modifications.
