Welcome to the first official episode of the performance advantage podcast with myself. Dr. Will O'Connor and Dr. Matthew Miller from MTB, PhD. Matthew, how are you doing?

Dr. Matt Miller 0:15

Thanks for having me.

Will O'Connor 0:18

And Mike Leishman, aka Kevin, has asked us about cross training.

Dr. Matt Miller 0:27

Ah, see. First episode, first shout out.

Will O'Connor 0:30


Dr. Matt Miller 0:31

Normally you built into the shout outs.

Will O'Connor 0:33

Yeah. Well, I guess we've sort of had a lead in from some of our previous stuff: cross training. I think this is gonna be a debate, to be honest.

Dr. Matt Miller 0:51


Will O'Connor 0:49

Well, I mean, when we talk about you know what.

Dr Matt Miller 0:51

Your intellect.

Will O'Connor 0:54

Yeah, okay.

Dr. Matt Miller 0:55

Okay. Well, maybe what we'll need to do is like, go over there and change your mind. You know how I mean.

Will O'Connor 1:04

No, I don't like the gym.

Dr. Matt Miller 1:06

Yeah, but you used to like the gym. Maybe you're just...

Will O'Connor 1:09

Yeah, I did. This is pre, pre endurance, Will O'Connor. Rugby and gym was definitely my game. Pushing the mass gainer. I definitely enjoyed that I got up to about 85 kgs. And Matthew?

Dr. Matt Miller 1:26

That sounds pretty big for you.

Will O'Connor 1:32

Yeah, it's about 10 kgs heavier than I am now. I've gotten... I found some photos the other day. It's pretty crazy how everybody changes? Matt, why are you pro gym, if we're talking about cross training?

Dr. Matt Miller 1:49

Well, there's lots of reasons why I'm pro strength training. And, the main reason is, because when you do like a really, really hard, heavy lift, you're creating these new neuromuscular junctions to these muscle fibers you already have. So, these muscle fibers are already there. So, if you're doing a squat, you have all these muscle fibers. And a lot of them you're not actually using, you're just kind of using the ones that you're using to bike or run. And there's some other ones in there that aren't being used. When you do a big heavy lift, the one of the very first adaptations that happens from strength training, is you get these new, neural pathways to use these muscles. And that's really good, if you're trying to produce more power, or run faster, or by car,

Will O'Connor 2:37

Would you not just do that on the bike? Or more running or whatever? Why are you specifically needing the gym for that?

Dr. Matt Miller 2:49

Well, because doing a one rep max, or a five rep max squat is way different than, you know, jogging up a hill or pushing a big gear. I consider those endurance training. And strength training is just a different thing that you can't do while you're doing endurance training, in my opinion.
