ProsourceFit Soft Medicine Balls are perfect for your daily gym or cross-training workouts and a safe way to incorporate power and agility training into your fitness routine. 14-inches in diameter, these non-bouncing weighted balls are a fun way to learn weight lifting techniques, strengthen your core, build explosive power and endurance and torch calories. Their consistent shape, size and soft, padded design make them super versatile for traditional exercises like squats, sit-ups and Russian twists, as well as full body exercises like wall balls, partner tosses, squat thrusters, twisting lunges and more. Unlike black and gray medicine balls that all look the same, ProsourceFit medicine balls each have a unique, vibrant color to make it easy to distinguish between weights. The strong, water-resistant shell is made of PU leather, with double-stitched seams for durability and long-lasting performance and the stitched logo and weight markings wont wear off. One of the oldest forms of training, these time-tested tools are still ideal for athletic training, home workouts, personal trainers and all gyms. Purchase all four sizes to complete your medicine ball set and keep your workouts challenging and effective!
