Re: stretching most effective in increasing muscle fiber number
I actually took the time to look it up yesterday. "Intermittent stretching" was attaching a weight to the bird's wing for 30 minutes (once a day maybe?) and had no real results.
Chronic stretching (which had amazing hyperplastic tendencies) was attaching the weight for -- get this -- 30 DAYS STRAIGHT. Wow.
Sounds like maybe it's not so easy to acheive hyperplasia, eh?
