When talking about the fittest woman on earth, one thing comes to mind:

Abs.

Also, insane strength, inspiring dedication, and a killer work ethic. Tia-Clair Toomey is all of the above and more, and fans were thrilled to finally see her standing at the top of the podium at this year’s CrossFit Games. While her list of qualities is a lengthy one, we’re not afraid to admit we’re dying to know how she has such a killer six-pack. Lucky for us, Toomey has been generous enough to share some of her favorite exercises for staying so lean and shredded. Here are some of her top core workouts.

1. Windshield Wipers

Don’t be fooled — these are way tougher than they look. Try one. Seriously — just one. Hanging from the bar (and making sure you’re not sinking into your shoulders), bring your toes as close to the bar as possible and lower them to one side. Bring them back and then lower them to the other. Repeat until your abs burn with the fire of a thousand suns.

2. Ab-Blasting Tabata

This one combines windshield wipers and sit-ups in the form of a tabata. See how many rounds you can get through before you enter the pain cave.

3. Planks on Planks

Planks are so challenging because they burn literally everywhere. If you’re feeling a little feisty and want to be tough like Tia-Clair, try adding weight like she did!
