Touchy subject here…
Take my personal opinion with a grain of salt, but I think much of Furey’s stuff is hype. I have had the fortune of speaking to someone very familiar with his marketing guru and the guy could sell you anything. Im not kidding. He could take any one of us on this web site and turn us into fighting/lifting/nutrition/whatever experts in the space of a one page article. It would sell too. I dont recall the marketing guy’s name right now, but he tries to recruit everybody he can that has an ounce of credibility.
He then builds a very aggressive advertising campaign around them.
For example, I dont know anything about the Great Gama, but the 5000 matches thing sounds like a bit of mythology to me.
Ive read combat conditioning and it has some good ideas. However, I dont think there is anybody on this website who would recomend a serious athlete train ONLY with bodyweight exercises. Furey trashes everything but bodyweight exercises because that is what he is trying to sell you.
Also, I know he has good wrestling credentials , but a lot of the grappling stuff that I have seen him pushing is pretty bogus(at least based on my experience).
Be very careful what you buy I guess. If you look around on the net, you may be able to find material on Gama’s conditioning program much cheaper if you are really interested. I remember guys saying that you could buy the Farmer Burns book Furey was peddling much cheaper on some historic site.
