DRINK YOUR PROTEIN

GET AN 'IRON' CORE

To sculpt his body for Iron Man, Robert Downey Jr. endured rigorous workouts at the hands of trainer Brad Bose. One of Bose's favorite toning tools for his celebrity clients? The AB-Inforcer, a device that gets your spine in a neutral mode to work your core muscles properly and uses sensory feedback to alert you when you're out of alignment.
