The Yonex Isometric TR1 Training Badminton Racquet is a specialized training racquet designed to help players develop greater strength, swing speed and shot consistency. Weighing approximately 118g, it is significantly heavier than a standard badminton racquet, helping build wrist, forearm and shoulder strength during training sessions. Featuring Yonex's renowned ISOMETRIC head shape for an enlarged sweet spot and a durable graphite construction, the TR1 is ideal for players looking to improve technique, power and overall on-court performance. Includes a unique mesh training cover that increases air resistance to further enhance strength development.
