5 Best Core Moves To Flatten Your Stomach in 30 Days

If you want to shrink stubborn abdominal fat, integrating core moves into your workouts is the name of the game. As you age, you naturally lose lean muscle—a process known as sarcopenia—which slows your metabolism and makes losing body fat more challenging. Building and preserving muscle kicks up your resting metabolic rate and supports your body in using fat for energy, says Leon Veal, level three certified personal trainer and head of nutrition and innovation at Styrkr. Below, Leon outlines five core moves to help flatten your stomach in 30 days—so listen up.

- Lift your right hand to tap your left shoulder.
