Jumping Jack Arm Lift
Start with feet together, knees slightly bent, arms hanging down in front of body at hip level and a 3-pound dumbbell in each hand (A). Jump legs out as you pull dumbbells straight up toward chin (B). Lower arms back down as you jump feet in to return to "A." Do 30 reps. Keep abs tight and dumbbells close to body.
Twist and Punch
Start with feet hip-width apart, arms overhead and a 3-pound dumbbell in each hand. Jump up, shifting weight to right side while pulsing arms up to right (A). As you land, immediately jump back up, shifting weight to left and pulsing arms up to left (B). Continue alternating for 30 reps total. Stay on balls of feet and really swing those hips.
