This Do-Anywhere, Equipment-Free Workout Works the Entire Body

Another move that simply needs a ledge, couch, or park bench: triceps dips into a reverse plank. Whoaaa! What a twist.

If you're at home, Ellie says to "sit on the couch facing the TV." From there, "place your hands next to your hips, plant your feet on the floor with your legs straight out in front. Inhale and bend your elbows, and dip your hips down towards the floor. Exhale and straighten your arms, squeezing through the triceps to extend. Lift your hips and open your chest to ceiling, squeezing your shoulder blades together until your body is a straight line from head to toe. Do not arch your back."

Muscles targeted: back, abs, and obliques
