So things like swimming don't have nearly as much of an interference effect on muscle growth as things like running, because it's an impact on your quads, right? You're trying to grow your quads, but then you're damp. You get the idea. So cycling doesn't have as much of an interference effect. It's not as landing. So all these factors go into it.

In terms of if you're trying to maximize muscle strength or growth. But that said, that running volume has to get pretty high for it to do any amount of interference. How much do you think you need to run to ruin your muscles? Depends on the person. If you don't run and I have you run two miles a day, that's going to crush you, right?

If you run a lot and you run two miles a day, it might not do anything at all.

No, no, no, there isn't. I would say for you, three to four miles a day probably is getting on the line of limiting muscle growth and strength if you're trying to maximize that. So here's what I'd say to you. All right, you want to get, let's get jacked, right? You want to get as big as you can. Like you want to go, you want to put on some muscle right now.

Can we back that off to like two miles a day? Just for the next, say, eight weeks. Great. And after that, we're going to change our focus a little bit. We'll put some miles back in. We'll see if we can maintain this new muscle and strength for as long as we can. But I can't have everything pegged all the way up to the top and then expect progress.

There you go. Right. Like, and then really was it a, was it this big molecular interference effect or was it the fact that it just took away your training quality? Right. It's not some big sciencey thing. You just didn't train as hard because of it.
