Dynamax was founded by two coaches who identified a gap in the market for specialist exercise balls which were strong enough to withstand high impact workouts but soft enough to not injure your partner whilst training. The Dynamax ball exceeds these requirements and has become the preferred choice for athletes for over 30 years.
All balls are 14” in diameter, moisture resistant and are made from 70% post-consumer recycled materials. Both design and construction ensure that they will remain dimensionally stable and balanced even after years of use. Our trade secret and craftsmanship guarantee that each ball, regardless of weight, has a friendly feel and will absorb high-velocity impact, making for a fun and vigorous workout.
Features:
- Engage your entire body and develop strength, coordination and endurance.
- Soft-shell construction absorbs impact while maintaining shape and weight balance even after repeated use.
- Easy to catch, impact-absorbing design.
- Perfect for strength and endurance exercises such as throws, squats, cleans and chops.
- Available in 6, 8, 10, 12, 14, 16, 18, 20, 25 and 30 pounds.
- Each medicine ball features a 14” diameter regardless of weight.

ABOUT FITNESS EXCHANGE
Founded in 1997, our company is a proud, locally owned and operated business. Our founder, Tom, had a deep passion for fitness equipment and noticed a gap in the local market. This realization led him to open his first shop in Conshohocken.
Fifteen years later, with his children grown, Tom immersed himself further into the business and expanded to the Lehigh Valley with a second storefront. He also ventured into commercial sales, providing a comprehensive, full-service experience to local gyms, schools, residential complexes, hotels, and more. This expansion established us as the go-to solution for fitness centerc’ needs. Over the past 25+ years, we have cherished becoming an integral part of the community in both Philadelphia and the Lehigh Valley.
