 Hey everybody, I'm Lance Coyke. Today, I want to do a really quick one on heart rate and how is heart rate impacting your exercise? So yesterday we talked about stroke volume being a way that we can deliver more energy. So basically the summary is I beat more blood on each heartbeat and that's that's just another way to get more blood to the rest of the system that is the body. The other way that we do it after we're while we're increasing the demands of our exercise is we increase our heart rate and everybody is familiar with that. That's something that you can really really feel. So when you start working out, you'll start to increase stroke volume first. So the heart tries to beat more efficiently and that's when you start to really feel your chest pounding and pounding and pounding on each one of those little sets. When you're weightlifting, you probably feel that pretty well. Because you're not really, you know, your heart rate never has to climb that high because you have so much rest relative to aerobic exercise. But if I'm doing more aerobic exercise, I'm going to start to run out of the gains that I can get from maximizing my stroke volume. And then the only way that I can get more blood to the rest of the system is by beating more often.
