Teasers Another core-targeting move, it'll only take a few reps of Teasers before you feel that burn. Take a seat and place one weight in each hand. Lie back and reach your arms straight to the ceiling. Extend your legs long on the floor. Zip your legs together and point your toes. Slowly activate the core to roll the arms and legs up to a "V" shape. Then, slowly roll back down. Repeat for 30 seconds. Rest for 15 seconds and repeat. Image Source: Pure Barre
