You and I are in the same boat tstowater. I've been doing it for 6 months. I am thinking I will like it for hunting training. I know my body and conditioning pretty well and I'm in as good a shape as I've been since high school.
I think a lot of it has to do with your coach and his philosophy. I don't think I would like it if we did 6-10 minute work outs all the time. Ours has been a good mix of the high intensity training along with strength and endurance training. Most of the strength stuff revolves around core and leg training so I find it very applicable. I also don't have any workout partners so going to the gym every day by myself for the last three years was getting pretty old and routine. I like the variety.
How many rounds did you get?
