High-intensity interval training, or HIIT, makes headlines in the fitness industry for its ability to burn the maximum amount of calories in a short period of time. But HIIT is anything but a trend. In fact, high-intensity exercise is something that our genes expect, and as you’re going to learn today, it plays an important role in fighting inflammation, regulating insulin sensitivity, and fat storage in the body.

On this masterclass episode of The Model Health Show, you’re going to hear the amazing science behind high-intensity interval training. We’re going to discuss the different types of muscle fibers in the body and how they function. You’re also going to learn about how energy is stored in the muscles, and how high-intensity training can help tap into those reserves. 

If you want to add high-intensity exercise into your training routine, I’m going to share multiple accessible, low barrier to entry methods you can incorporate. I hope this information empowers you to become a stronger, more resilient version of yourself. So listen in, take good notes, and apply what resonates with you!  

In this episode you’ll discover:

• How moderate-intensity cardio compares to high-intensity interval training.
• The definition of high-intensity interval training, or HIIT.
• How our muscle fibers work, and how they can impact metabolic health.
• What the different classifications of muscle fibers are. 
• How the sequential activation process works.
• Why sequential activation is the key to metabolic change & body composition shifts.
• The relationship between high-intensity exercise and glycogen.
• What glycogenolysis is. 
• Why high-intensity exercise can impact fast-twitch muscle fibers. 
• The link between obesity and inflammation. 
• How fat loss actually works & the role that hormone-sensitive lipase plays. 
• The amplification cascade that occurs in the cells with HIIT. 
• How glycogen storage works. 
• Why intensity is key, & how to know if you’re activating the fast-twitch muscle fibers.
• What we can learn about exercise from children.
