Hi everyone...the "Muscle Nerd" here!
When Marc first told me that Tom and I were pitted head to head in bodybuilding principles within the DB forum, I can't say that I was exactly happy about the situation for a couple of reasons...
1. I have a great amount of respect for Tom, his work, and what he's accomplished and I know how forum conversations can degrade into "so and so doesn't know $#&*!" from loyal users of a program. I'm hoping that none of the Optimum Anabolics guys follow that path...Tom has a great program! And...
2. I think the forum readers can get too caught up in the minutia of this one factor and finding the "perfect formula" that they miss the boat on more important elements of building muscle.
In any case, I'll save everyone a lot of debate...
Does Tom's "slow concentric" rep build muscle...YES!
Does my "fast concentric" rep build muscle...YES!
Which one builds it better? Hmmmm....
Look...there are mountains of evidence on both sides about which works better. The most important research that you'll find valuable will be "what works better for YOU?" If you haven't USED (yes...actually USED!) both of our methods in the gym for a few months, and MEASURED (yes...MEASURED!) your results, then please refrain from an opinion. One sided ones are the worst! In the end, the basic truth is that what works best for one guy doesn't work best for ALL guys, right?
Now, just so I don't totally stray away from actually giving you a fair assessment of WHY I've found fast concentrics to be the best option for my training program, I'll offer a bit of a simplified explanation...
Your muscle fibers are basically comprised of 2 different types of fibers: Fast Twitch fibers which primarily function as "strength and power" producers because they carry a larger store of creatine phosphate and ATP, your body's main "short term" energy producer; and Slow Twitch fibers which, due to a much larger number of capillaries, have a larger blood supply and have a larger ability to "pump" up the muscle tissue during exercise which will ultimately result in increased thickness of the muscle fibers themselves as capillaries become denser and more blood is pumped through the tissue.
Now, since each muscle fiber has a different function, they also have to be trained in a specific way in order to maximize the stress to the muscle cells. It's similar in concept to how you train your chest as opposed to how you train your arms. These muscle groups have different functions in the body so you train them differently, right? Therefore...
Fast Twitch muscle fibers are best trained with heavy weights and low reps while Slow Twitch fibers require a faster movement for higher reps in order to "pump" more blood into the muscle tissue. But as another poster pointed out, this is "body building" and it just makes sense to train for BOTH types of muscle fibers in order to maximize size and function. THIS is why I combine both movements into one repetition.
This is a simplified view and if you'd like a more comprehensive explanation, you can receive the entire chapter of my program that specifically deals with this principle...and yes...it's FREE!
Just go to my home page (

Now...a word of caution here...
Don't let a single concept of your body building plan like rep speed determine the effectiveness of a single program. The fact is both Tom and I have great programs which cover a much wider range of the factors you need to build muscle and burn fat and which one works for you will be entirely up to your USAGE of the programs and close tracking of how your body responds.
So...to the forum readers...find what works for you through research, trial, error, and success and stick with it! (Oh, and yes...I've heard the call and have now put a photo up on my site...although I'm nowhere near as pretty as Tom!)
And to Tom...my hat's off to you bro! Keep up the great work!
