“Explosive” Mass Research Wrong?

Cyclists' quad development

Q: I read with interest your explanation of [researcher] Chris Beardsley’s take on explosive movements. If he’s right and the 2X explosive fast-twitch fibers don’t have hypertrophy potential and explosive actions can cause a transition of other type 2 fibers into 2X, how do we explain the muscular quads and calves of sprinters?

New Muscle Size With Speed and Progression

Heavy bench press

Q: I am almost 50 and making incredible gains with the 4X method. I was reading that top trainer Charles Glass believes new muscle growth can be created with this style, thickening new fibers as well as expanding the sarcoplasm. However, he says you should still go “heavy” every so often. Every time I do that, my joints ache for days. Should I just put up with it and pile on the poundage every couple of weeks?

I really want to start The Ultimate 10×10 Mass Workout [that uses only the Ultimate Exercise for each muscle group]. My problem is that I’m not convinced the 10×10 method will work. As much as I want to try the routine, I’m not sure I’m convinced that using lighter weights can really build muscle.

A: For the uninitiated, 10×10 is taking a weight you can get 20 reps with, but you only do 10. You rest for 30 seconds, then you do 10 more and so on until you complete 10 sets of 10 reps.
