And how is the adherence with your patients when you tell

them? Okay, your heart rate is not allowed to go over X and they go out for a walk and the minute there's the slightest incline or they want to put a little bit of kick and anything they're doing, they're out of zone two and they're like well this is I

try to I try to keep them separate. So I've actually found outdoor walking and outdoor running to be very difficult for Zone 2. So just like when I go rucking, I mean, my heart rate is sometimes. I'll hit max heart rate if I'm going to steep enough. He'll so I just consider that a separate form of exercise, but like a stationary bike, yeah, it is uninteresting as it is. I mean, I'm on a stationary bike when I do it because I can control it and I just we try to have patience. Do it on a treadmill stationary bike. Rowing machine super controlled swimming is good too because you can really control your pace but outdoor cycling and outdoor walking running or Harvey variables. So I which is we don't want to Courage, people from doing those things, but we do want to acknowledge use those for maybe where you get your zone 5.

Hmm. Interesting.
