Running doesn't build muscle?

sweetxsour35

I've heard so many things about how running doesn't build muscle. I'm on week 4 of C25K and my calves are rock hard, so how is that not muscle? They definitely weren't like that before.

I'm just curious as to how it doesn't build muscle. You don't see any runners with twiggy, wimpy legs.

If you are trying to build muscle, then extended cardio, aka distance running is counter productive.
I dont run, ever, unless someone bigger than me is chasing me.

like me. RAWR xD

I actually see many runners who look like they would blow away on a windy day

Running won't bulk you up but it will tone and define your muscles. One thing I most definitely notices was the change in shape of my upper body. My chest tones up, my neckline became more defined and my arms became toned.

Yup this is because cardio is helping you burn the fat around the muscle :] So your muscles can poke through. Not building any!

When running you are strengthening and toning you muscles. When weight lifting you are bulking. You are not necessarily adding muscle but you are strengthening what you do have which is why your legs are getting harder. Sounds like you are doing good on your couch to 5K!!! Keep it going!!

I currently only do runs, mix of track and trail runs about 6 miles each time. I have no built up huge muscles on most of my body, I have actually become very petite in my upper body. My lower body has lost a lot of fat, but everything left there is rock hard muscle, and my legs by no means look bony.

Jeez. I wish that would happen to me already. :grumble:

I guess I just have too much fat to burn off to see a difference yet!

Hmmm, you'll burn fat but you will build a small amount of muscle, especially if there wasn't much muscle there to start! Just look at the size of some sprinters! Massive!

A lot of what you read about "bulking up" are written by and for body-builder types that have already achieved a high level of fitness. They don't always take into account how things are different for people just starting out.

What they mean is somebody who already has well-developed leg muscles cannot develop them more by running. For somebody starting out, the leg muscles are not developed and can grow to some extent but will not get huge.

Yup! Sprinters are beefy Distance runners not so much

HIIT is better for that. Distance running is counter productive.

You cannot build new muscle tissue unless you eat a calorie surplus along with doing some kind of resistance training.

Also before people speak...yes I realize that if someone is morbidly obese they can use the bodyfat stores they have to burn as energy (calories) which can provide some new muscle tissue, but this isn't as cut, dry, and simple as you think. Also women do not build muscle tissue like men do unless they are on the juice.

Running is a load-bearing exercise. You're not lifting MORE than what you weigh, but you are lifting your own weight.

Thats fine and all, but you are only toning the muscle you have while burning the fat unless you are eating a calorie surplus. Also at some point you will stop building new tissue unless you increase resistance. Just saying. :P

SmartFunGorgeous

I noticed a definite toning when I first started running as well, but once I added in resistance training as well, is when I really started noticing more musculature.

Um, there are a LOT of women with PCOS on these boards. They should be aware that the usual wisdom about women not bulking up with weight training is not necessarily true for them. If they have elevated testosterone levels from the PCOS, they need to hold off on using heavy weights at all - unless they WANT to get bulky. Most women with PCOS do have elevated testosterone. Only a blood test can tell them for sure.

Light hand weights are usually okay.

I have PCOS. I lift heavy 3 times a week. DO you see me bulking up? Im kind of small really.

I understand what you're saying but still they will not get bulky unless they are eating a calorie surplus regardless of the condition. It doesn't work the way you think it does.

One thing I'd like to add is that women with PCOS are more insulin resistant which makes building muscle that much harder.

Running (long distance) will harden the existing muscle and usage will fill it somewhat. Typically aerobic activities does not lend itself to the creation of new muscle tissue or hypertophy of muscle tissue to a significant amount.

Sprinters will gain massive legs in comparison to long distance runners, because sprinting is an anaerobic active that is explosive in nature. This very much contributes to the development of new muscle tissue and hypertrophy.

For someone who's typical exercise is lifting the remote control, taking the trash out and folding their laundry; both kinds of exercise will do wonders in leaning and hardening them at first.

Over time an aerobic only program will quit promoting strength and muscle development other than increasing endurance. As the body becomes leaner, there is even the potential that upper body muscle tissue may actually decrease due to it becoming a physiological liability to the long distance runner.

A great example of this is looking at a marathon runner

vs. a decatholate

you can the difference in development based on the need induced by the activities.

The question is what kind of fitness activities do you want to engage in and what kind of look do you want.

Meds and diet will often improve the insulin resistance profile before the androgen levels drop. This is information I received from the PCOS specialist I consulted and which has proven true for me. Lets talk when you have lived with PCOS for even a day.

LOL @ your last sentence. Once again, women will not bulk up unless they are eating a calorie surplus.

Must have skipped over my comment? I have it too. HE IS RIGHT. Once again, I lift 3 times a week. and HEAVY. Do i look bulky to you?!

You are way too bulky............... :-)

You are not bulking when you are lifting weight unless you are lifting heavy. You can tone and define by using small dumbells, and using just the bar with no weight on them, and I could go on for days but just saying that lifting weights doesn't necessarily mean that you are bulking!

Thanks for the help, guys! BTW I didn't know this would become such a debate!
