Abs―Part 2

Minute 3: Sideways Shuffle (cardio)
Stand with feet shoulder-width apart. Step to the right with right foot, then quickly bring left foot to meet it. Repeat, picking up the pace as you shuffle sideways all the way across the room; return with left foot leading. Continue going back and forth for a full minute. 

Minute 4: Dead Bug (toning, pictured)
Lie on back with hands by your sides, knees bent at a 90-degree angle, and feet off the floor. Tighten abs, and slowly lower left leg toward floor, straightening leg, as shown. Stop when you feel lower back coming off the floor. Return to starting position, then switch legs. Alternate for one minute.

Minute 5: Football Drill (cardio)
Stand with feet shoulder-width apart. Run in place as fast as you can. Take periodic 10-second breaks to jog, if needed.
