2. Plank butt kicks

This move not only builds strength through the core, but by adding the butt kicks you’re getting a hit of cardio. You can see why this is one of my faves!

» Start in a planking position on your forearms and elbows, butt down and hips up.

» Your body should form a straight line from shoulders to ankles like, well, a plank.

» Engage your core by sucking your belly button into your spine. If you’re on struggle street, don’t drop your hips or arch your back, simply push your butt up to the sky.

» Hold and add the special ingredient: butt kicks! One leg at a time, bring your foot up to your butt, kick it, then lower your foot back to the ground. Alternate legs, go as fast as you can, but don’t lose that planking form!
