Its a solid program. This year, 3 of the 8 man US team to go to the Pan American games in Olympic weightlifting are coached by me, and all have used the "texas method" quite a bit in their training. Like any program, its not the end all be all of training, but it gets you stronger and bigger.
Here are three videos of a 265lb, 19 year old kid clean and jerking 446 lbs, a 204 lb kid clean and jerking 408 lbs, and a 235lb man clean and jerking 464 lbs, respectively, all drug free, and all built a lot of their strength on programs similar or exactly the same as what is now called the "texas method", although I didnt call it that when we first started using it. Someone else came up with that name.
