Diameter: 65 cm Togu Gymnastics Ball BalanceSensor: Modern coordination training - The Togu Gymnastics Ball BalanceSensor consists of the Togu ABS-Powerball, which is completely safe from bursting thanks to its anti-burst system, and a removable strap. The movement sensor fits into the strap and transmits data in real-time to the Bodyteamwork app. This allows you to train playfully based on your movements via tablet, smartphone, and Windows PC. For example, you can navigate a skier through slalom gates by shifting your center of gravity and safely guide your avatar to the finish line. The great advantage: Balance training with the gymnastics ball is done playfully and thus subconsciously. Additionally, in group classes, participants can train independently, regardless of their skill level. The instructor can then provide targeted assistance to individual participants. The sensor is powered by a CR2032 battery (not included). - Product details: - Material (strap): 53% elastane, 47% polyester - Weight 55 cm: approx. 1,360 g - Weight 65 cm: approx. 1,620 g - Weight 75 cm: approx. 1,690 g - Color (ball): Gray - Color (strap): Black - Recommended body heights: - 55 cm: 156 to 165 cm - 65 cm: 166 to 178 cm - 75 cm: from 178 cm Features: Anti-burst system Ball type: Sitting ball Application area: Rehabilitation, training, therapy Load capacity: up to 150 kg Diameter: 65 cm Max. load capacity: 150 kg.
