In this video, we’re going to talk about why exercise intensity is important.

Let’s take a look at the “anatomy” of exercise. What makes exercise effective for supporting your health?

There are four variables to look at:

1. Duration

2. Intensity

3. Recovery

4. Frequency

Our focus today will be on the intensity of exercise.

High-intensity workouts have many benefits. Take a look:

1. Produces a greater increase in aerobic capacity, which boosts the amount of oxygen delivered to the muscles, promotes exercise recovery, and improves stamina.

2. Greater reduction in risk of cardiovascular disease and premature death.

3. Significant improvement in insulin sensitivity.

4. Significant increase in growth hormone, which promotes fat-burning, immune function, calcium retention, and thyroid hormone conversion.

Overall, research suggests that short bursts of high-intensity exercise, like HIIT, are better for a healthy body than prolonged workouts, like running a marathon.

HIIT is a great addition to the Healthy Keto and intermittent fasting plan.
