Sculpt your core with this five move core workout by January 2018 cover model Tiffiny Hall.

GEAR: none! GO: 20 seconds’ work, 10 seconds’ rest, 4–6 rounds (push yourself!)

1. V-snap to push-up with a sexy roll

What a move! This exercise works your whole body, focusing on your core and adding a cardio twist. We all know we can’t spot-reduce fat, so it makes sense to combine a core-strengthening exercise with full-body function movements to burn calories, right?

» First up, the V-snap. Lie on your back, pushing your belly button down into your spine so there is no space between your lower back and the floor.

» Lift your arms over your head and perform a sit-up. At the same time, lift your legs (keep them straight) to make a V with your bod and reach for your toes. This is the snap!

» Lower your arms and legs slowly.

» Now for the sexy roll. Roll over so you end up in a push-up position. The trick is to roll on your elbow and forearm, and to roll fast! The faster we move, the more calories we burn.

» Perform one push-up (knees or toes), lower your body to the ground and sexy-roll back to starting position, ready to throw your arms over your head and snap again!
