Watch any World Cup race and you’ll see athletes employing incredible core strength as they hurtle downhill. Let’s look at exercises to strengthen your core musculature.
Many of you have likely done sit-ups and crunches at some point. Fifteen years ago, I was that guy doing sit-ups on a decline bench while holding a 25- or 35-pound plate.

Shirley Sahrmann notes that crunches train the rectus abdominis and internal obliques, but not the external obliques. Even a twisting crunch — say bicycles or Russian twists — don’t adequately train external obliques.
