Key benefits Adjustable height and resistance lets athletes tailor training to their current level and goals — from beginner techniques to advanced explosive work. Targets vertical jump, explosiveness, and contact timing to improve spikes, tips, and touch skills. Durable construction designed for frequent practice so you can train consistently without rapid wear. What it does (function) Provides controlled bounce and resistance for jump and contact drills, reinforcing takeoff mechanics and reactive power. Adjustable difficulty and height settings make it usable for progressive training and skill development across all stages. Who it’s for (compatibility) Suitable for volleyball players at all levels: beginners, club players, and professional athletes. Designed for use in indoor or outdoor volleyball training venues, including gyms and training grounds. Key attributes Adjustable height and difficulty: adapts to different drills, body sizes, and skill levels. Materials: made from elastic bands and belt materials engineered to withstand frequent training and long-term use. Performance focus: improves bounce, explosive power, spike force and touch precision through repeated, controlled practice. Practical use scenarios Team practice: Set up on the court during team sessions to run repeated approach-and-spike drills with consistent resistance for explosive development. Individual training: Use in the gym or on an outdoor court for solo jump and touch drills to hone timing and increase vertical power. Skill refinement: Incorporate into technical sessions to work on hand contact, soft touch, and controlled spikes under resistance. Why customers need it Offers a simple, repeatable way to develop verticality and contact skills without complex equipment. Adjustable settings keep the same device useful as athletes progress, reducing the need to buy multiple tools. Robust materials support frequent use in training environments, making it a reliable part of regular practice routines.
