Have you seen this clever setup to replace a sled?
Yes, the weight of the training line (the long one) influences the resistance. Especially when the line lays on a tartan surface (what is the case mainly). When you extend the trailing line on the ground it will add a certain amount of resistance due to the friction of the line on the ground.
The benefit of this effect is that you fatigue the primary and secondary muscle fibers through the range of motion and as it moves back towards the unit.
The Exer-Genie hub and shaft Assembly is warranted from defects for 5 years. We’ll repair or replace it postage prepaid. We have units that have been in use for 40+ years depending upon care. The unit gets hot under heavy use and that’s why we recommend several in a Team situation.
The casing is of a high temperature resistant plastic yet will show signs of wear and tear because of handling and from the heat from the shaft and hub. This doesn’t affect operation it’s more cosmetic wear just like any other training tool.
