Hi, everyone, real quick before we get into today's episode. This podcast is a labor of love,

and I do it for free. I spend hours each week researching to create these episodes, all with

the goal of spreading science-based fitness information. And I want to continue releasing episodes

one to two times per week, but I need your help to grow it. So if you could do me a huge favor

gets up when I'm strength training. Does that mean strength training also doubles as cardio?

So these are things that I want to discuss today. And these are things that I've honestly

had the question about and haven't really fully understood until I dove into the research

about this. So first of all, why do cardio? What are the important adaptations to your health? Cardio, at least steady-state

cardio, like running, biking, swimming, et cetera, our steady-state class, imposes continuous and

sustained demands on the same muscle groups, therefore creating really consistent oxygen
