Mario Sperry Vale Tudo 1 - 6 DVD Set
Product Review (submitted on March 16, 2008):
Though the material is pretty good, a lot of it is outdated for modern MMA. For example, Sperry shows things like headbutts and strikes to the back of the head which have since been outlawed in competition. The techniques also get a little repetitive after a while. On the other hand, a lot of this stuff is still good for street defense. Although somewhat outdates, it's still a classic. A nice bonus was the fight footage!
