This is part of a campaign that highlights not just the benefits of these balls, but what they truly mean to the athlete they are created for, Trey Hardee, the reigning world champion decathlete, who describes his workouts with Dynamax as his daily medicine. Each workout is just as tough mentally as it is physically, which is why a portion of the sales benefits his foundation, The Flatwater Foundation which helps families coping with a cancer diagnosis. Whether it’s training for the Olympics or supporting your family, mental toughness is how you win the fight.
