Properties: The exceptionally durable and comfortable construction of tiguar Slam Balls, designed to be struck on the floor, guarantees effective training that improves overall strength, explosive power and full-body endurance. Dynamic exercises with the Slam Ball, which doesn't bounce when it hits the floor but stays in place, are commonly used in CrossFit training and by athletes who prioritize speed. The extensive use of the balls in this type of training requires above-average durability, which is guaranteed by the materials used in the tiguar Slam Ball. The balls' stability is guaranteed by being filled with sand (weights ranging from 4 kg to 12 kg) and a mixture of sand and cast iron sand (weight 15 kg). The comfort of slam exercises is influenced by the design of the ball's outer surface, which must provide a secure grip and prevent slippage. Therefore, its surface features honeycomb-shaped protrusions. The tiguar Slam Ball is available in six weights that increase by an average of 2 kg, allowing exercisers to make steady, gradual progress. The Slam Ball is another of our brand's phthalate-free products. Available weights: 4 kg, 6 kg, 8 kg, 10 kg, 12 kg, 15 kg First training session: Before starting training with the tiguar slam ball, wipe the ball coating with a damp cloth to obtain a clean, grippy surface.
