Timely post Steve.
I would say that intermediate level is the absolute bottom range for anybody thinking about utilizing some of the adanced specialty programs. Even after I had reached the intermediate level on all of those lifts I was still making good progress without resorting to specialty programs.
Another thing to consider is who wrote the particular program, and what type of strength sport was it geared for? What level of athelete was it really intended to be used by?
Some of these programs were designed to be used by Elite level professional athletes. Are you a professional elite level athelete? Do you have a coach who is watching your training, and making decisions for you, or for your team?
Some of these programs are no different than looking in the latest issue of your favorite muscle mag at what the new Mr. Olympia did for contest prep. It has absolutely no bearing on how you should be training.
A squat routine developed for a powerlifter, will have little benefit for an olympic style lifter. The two styles of lifting are so different from each other that even the type of barbell used is not always the same.
Go here and check out the equipment.
The world's most famous bar - Eleiko
Notice on the Eleikosport barbells that they have WL bars, and PL bars.
Then there is this bar.
Texas Power Bar
They are completely different from each other.
If you are not well above an intermediate level of strength, fast approaching advanced, you probably should not be worried too much about some of the
exotic programs. Just keep your head down, and keep working, you'll get there. You'll get there faster if you concentrate on where you are now, instead of where you hope to be in the future.
