Iron Jumping Jack
Targets: Shoulders, abs, and legs
Kristin says: "We were in Morocco shooting Sex and the City 2; I couldn't run, because it was so hot and we were working long hours." Instead, she sneaked in her cardio by doing these jumping jacks in her hotel room.
- Stand with feet together, holding a 2-pound dumbbell in each hand, elbows bent so that weights are in front of shoulders, palms facing each other.
- Jump feet out to sides, landing with feet wide, as you press dumbbells overhead to form a V-shape with arms.
- Lower weights to shoulders as you jump feet together.
- Do 30 reps.
