The importance of the GXBolt drive arm attachment. When we looked at the development of power that creates the applied force, there was nothing on the market that helped athletes. Knee drive, which is one component of stride frequency, is a vital aspect of sprinting. It is the forces applied at high frequency which makes the greatest difference. This is one major reason why GXBolt-963 stands alone and is making the biggest difference for athletes and programs!
When pushing a traditional sled, the leg is only met with resistance once the foot strikes the ground. GXBolt-963 patented pulley system gives athletes the dynamic ability to develop power as the leg transitions from knee drive to push. This major feature develops explosive athletes by significantly improving their ability to apply greater force into the ground.
