Lie faceup with feet flexed in the air so body creates a 90-degree angle and arms are rested palms down at sides. Use core to pulse legs straight up towards ceiling, lifting butt off floor and pushing weight into hands. Think about stamping the bottom of your shoes on the ceiling and avoid using momentum to swing legs forward and up. Lower back to floor and repeat.
“For me, getting a six-pack was about paying attention to what I was eating and lifting heavy weights at CrossFit. I do have a semi-strict diet, and I loosely count macros (focusing on daily carbs, protein, and fat intake rather than blindly counting calories) to stay balanced and on track. It sounds like a lot of work, but it really isn’t. Eventually, it just became a part of my lifestyle, and it’s something I enjoy doing. I even started a custom meal-plan business based on macros because I had such great results!” —Tina Haupert, @carrotsncake
