His flexibility cds are really excellent, as are the energy exercises.
His bodyweight stuff could be better at being progressive bodyweight exercises, but it is good in so far as it builds muscle endurance and you can hit many muscles simultanously from various angles, which is what I use bodyweight for. If I want strength I use isometrics and certain weight exercises.
We also have to bear in mind he was the first to bring back such exercises.
Things have their place, and most of Matt's information and products is very good, some of it extremely good.
