i was wondering if running will show significant improvement to your legs below the knees. i never run but now im starting to run for 30 minutes 3 times a week. will this increase the mass of my legs or no?
I hate to say it, but It Depends (tm).
I've known sprinters with excellent calves, but relatively few distance guys with any lower leg musculature to speak of. I think 30 min. running would, unfortunately, qualify as "distance running," but I've known a _couple_ of those guys who had good legs. A couple.
For the most part, I'd guess only guys carrying a lot of weight and who run (or walk) a good bit would get this growth. For example, have you ever seen how big some fat people's calves are? It's not all muscle, of course, but just by carrying their weight around all day something might work in their favor.
At the risk of being long-winded (yet again), though, that could just as easily be, and probably is,
genetic. The fat guys or otherwise skinny distance runners with good calves might've had them anyway
On that basis, I'd conclude for those with less than ideal calf genes, running is not the most efficient way to go. It's possible running could actually cause overuse atrophy, but you'd have to find that out for yourself.
Like any other bodypart, progressive weight training for calves is by far most likely to get the results you're after. Are you training calves now, and if so, what does your routine look like?
