Stationary Trainer Accessory
Heel weights are a great addition to stationary (spin) training for performance cycling.
I have used such to recuperate from injury (retuning muscle balance) and regular training as well.
More info @ gg-fit.com or EBAY auction "business industrial, heel weights"
Conversation about such devices and their usage methods needs to be struck by those who would seek to keep up
with the fast group year over year.
