Today, we speak to world-renowned coach Joel Jamieson about all things cardio. We love to talk about resistance training on this show, but it’s finally time to show cardio some love. Joel tells us all about why cardio is one of the most important activities we should be doing for our health. We go through what the different heart rate zones are, how cardiovascular training is different from resistance training, how you can balance the two, and how cardiovascular training changes your mitochondria.

This is an update to our last episode on alcohol. New research has been accumulating suggesting that perhaps even a glass a day of alcohol is not beneficial. For instance, the new Canadian guidelines say that zero alcohol is the safest amount of alcohol. Today, we revisit the topic with Professor Mariann Piano, Senior Associate Dean for Research, Postdoctoral Fellowship Director at Vanderbilt University.

Is there anything better than a piping hot cup of coffee on a frigid winter day, or the first cold brew of a beautiful summer? For a lot of us… likely not. Coffee is the way we kick off a day, pick up an afternoon, and rehash the work week with a friend on the weekend. Besides saving us an untold amount of cash, is there any health benefit to giving up coffee? Or is it actually making us live longer? Today we talk Professor Rob Van Dam from George Washington University and answer the question of caf, decaf, or no-caf: what science tells us about coffee, caffeine, and health.

A cocktail with your friends, a glass of wine after work, a beer at a barbecue–alcohol is everywhere. Undoubtedly, it’s been an integral part of our society for thousands of years. But when it comes to its effects on our health, results can feel more mixed than your favorite margarita. Is alcohol a “poison,” or maybe, in moderation, is it actually ok, or even good for us?

Today, we interview Professor Dan Lieberman all about why exercise doesn't have to be that stressful or complicated. A look at exercise through the anthropological perspective, and why its normal to not "feel like it" sometimes. Find out the answers to questions like: is sitting actually that bad for you, how much do we need to exercise, is there such a thing as exercising too much, and more.

You may have heard online that calorie restriction, or intermittent fasting, or both combined actually make us live longer. But what does science have to say about this? Today, we talk to Professor John Speakman about the science of calorie restriction, health, and longevity. What does being hungry have to do with being longer?
