Exercise is a stress to the body. It is disrupting the equilibrium of your body, which your body interprets as stress. This means exercise will spike cortisol.
Chronically elevated cortisol will result in problems in your body, as I discussed earlier. However, studies show that regular exercise can improve your stress response, even though it acutely spikes cortisol acutely or right away.
So the answer is not to stop exercising all together. The answer is to figure out how to dose exercise so that your body responds favorably.
A common thing I've been told from my Evlo members is that they work out less frequently and intensely with my program, and yet they see more desirable changes in their bodies.
This change happens partly because of the exercise selection we are choosing - we are intentionally choosing exercises that load the muscles in the most effective ways with minimal joint stress. That results in better muscle adaptation with less painful joints. But it...
Many medical and sports groups suggest intense interval training shouldn’t be completed more than three times/week to avoid these negative metabolic side effects. And from a joint health perspective, I agree that HIIT should not be used more than a few times/week, if at all.
So if we can only gain the benefits of HIIT 2 to 3 days a week, are we just sedentary on the other days? Should we train in different ways on the days where we aren’t working out intensely?
The study took overweight men, divided them into groups, and had them exercise on a bike for a different amount of time and intensity.
Group 1 performed short, all-out workouts on the bike such as 30-second sprints with minimal rest in between. This group only exercised 3 days/week.
Group 2 exercised more moderately: 30-40 min on the bike...
Over the next two weeks, I want to talk about cardio: what it is, how much you need, and, most importantly, how much is overkill and could be setting you back.
Most people agree that cardio is anything where you elevate your heart rate. When I was looking at the formal definitions, most will say that this requires rhythmic, repetitive movement of your limbs.
Because most people consider cardio as repetitive/rhythmic moments, when most people think of cardio, they think of activities such as running, cycling, and swimming. This is also why most people don’t include weight lifting when they think of cardio.
Therefore, it’s commonly thought that you need to do both: lift the weights and add on the running or biking.
But do you really? And if so, exactly how much should you do?
These are the questions I want to address over the next couple of weeks. We’re going to talk about the benefits and risks of different dosages of...
