This makes our abs burn just watching. The fittest woman on earth has always been generous with sharing her workouts on social media. Recently, she showed us a little core workout she likes to do, consisting of roll-outs and L-sit holds. For the roll-outs, you can use an ab wheel like Tia, or a barbell with some change plates on the ends. Roll-outs (and L-sit holds, for that matter) aren’t just ab workouts. You’ll feel it everywhere. This must explain why she’s so shredded. Now, get to work, and let us know what you think!
