Hey I posted this on EZA/Joels site with pretty much no response. But I know a lot of folks here use his methods. Has anyone incorporated large tractor tires, or even smaller ones ALA Houlton Alexander throwing tires up a hill, in to your training using Joels methods? I'd be interested in different ideas using tires. I used a roughly 400lb tractor tire the other day for the Cardiac Power method. We basically just flipped the tire for 60 seconds, then would take a 2 min break...repeat several times. So if you've used them succesfully based on the different methods/energy system training, post it here, thanks.
