Hundreds to Roll Up This move targets the abs and arms. Take a seat with one weight in each hand. Roll back, chin to chest, shoulder blades hover the floor. Extend your legs straight on the 45-degree diagonal. Zip them together and point your toes. Reach your arms forward. Slowly alternate "walking out" the arms, with 4 switches, then hold the arms straight. Slowly roll up as you bend your knees to your chest, then slowly roll back as you extend your legs to the diagonal — 2 roll ups. Repeat for 30 seconds. Rest for 10 seconds and repeat.
