Hey all, just a quick question about something that’s bugged me for awhile.
We’ve all heard the general rule: if it’s fast-twitch, hit it with heavy weights, for lower rep ranges. If it’s slow-twitch, hit it with high reps.
What I don’t understand is…how does working our slow-twitch fibers with relentless high reps/minimal weight do ANYTHING for their growth? Long distance runners work the heck out of their slow twitch fibers, and have no muscle to show for it.
Am I missing something here? Is there a good way to get type I fibers to actually get larger and thus contribute to muscle “fullness”? I’d always heard the more you train the type I fibers, the thinner they’d get to due becoming more efficient at gas exchange?
Instead of going high reps for type I’s, couldn’t we do high “volume” instead?
Just something that’s been on my mind for awhile and I haven’t asked on here yet. Thanks for any input…I realize I may just be missing something here.
