Perfect for solo training - This volleyball training equipment helps the ball return after each swing so you can spend more time hitting volleyballs and less time chasing them. You don't need to interrupt your training to retrieve the ball, allowing for hours of practice without needing another person. This ball pocket is easy to hold balls, just use one side strap on the ball pocket to attach the other side strap as needed. Improve ball control skills - Improves player's touch, setting, spiking, overhand or underhand serve, arm swing passing, ball control and throw-in, which can easily warm up before your match or improve your volleyball game skills better. Adjustable waist strap and elastic cord - This strap pad sits comfortably around your waist and protects your waist better. It can be adjusted to fit different waist sizes for most players. The elastic cord gives you enough length to even hit overhand serves and spikes without the ball bouncing back in your face. Standard hand movement - Use the adjustable straps with plastic knobs reinforced to rest steadily on the palm to reinforce correct hand placement on the ball to standardize hand movement or reduce inaccuracies while setting to avoid touching the ball during practice. One size fits most balls - Designed with a ball pocket that can be adjusted to hold all sizes of sports balls such as volleyball, soccer, beach volleyball, water polo, even a basketball. Excellent training equipment for all experience levels from beginners to experts.
