How to do it: Grab a pair of dumbbells (depending on your level, try 3-10 lbs) and stand with feet wider than hip-width apart, toes slightly turned out, palms facing forward.
Bend your knees (keeping them over your toes) and bring the back of your hands to the inside of your knees.
As you straighten your legs, scoop your arms up in front of your chest, keeping your arms extended but elbows soft, and tap the ends of the dumbbells together lightly. That’s one rep. Do 3 sets of 15 reps.
Targets: legs, chest, arms
