STREXBOX Disc (S-M-L)

The Kynett STREXBOX resistance discs are engineered to deliver maximum inertia and training output within a compact flywheel system. Designed specifically for the STREXBOX, each disc generates a high level of resistance, allowing users to achieve a strong training stimulus without the need for large or complex setups. The STREXBOX disc system provides exceptional resistance per disc, outperforming traditional flywheel systems and enabling efficient, high-intensity training. Each disc level is optimised for different training goals: S Disc (0.038 kgm²) Ideal for controlled movements and rehabilitation, delivering peak forces up to 90 kg (198 lbs) M Disc (0.086 kgm²) Designed for strength development, reaching peak forces up to 130 kg (302 lbs) L Disc (0.104 kgm²) Built for maximum resistance and eccentric overload, with peak forces of 200+ kg (400+ lbs) Adjustable Resistance The STREXBOX allows you to train with up to three discs, making it easy to adjust inertia and training intensity by stacking discs. This flexibility supports a wide range of training applications: ✔ Strength training ✔ Power development ✔ Eccentric overload ✔ Rehabilitation
