• Begin with elbows on physioball and feet on ground
• Form straight line from your shoulders to knees by activating core and drawing in stomach

Sets/Reps: Begin with 3-5 30-second holds and work up to 2 minutes
Advanced: Add a dynamic element:move the ball in Figure 8s, I’s or T’s throughout duration of hold
Benefits: “This is great for working the lower abdominals—the muscles that control the pelvic area during explosive movements, which is important for sprinters and athletes who have to change direction.”

The Big Picture: “Perform this exercise toward the end of a training session during core work.”
