What’s All the Buzz About HIIT (High Intensity Interval Training)? hiit-image

What exactly is this, and why has it gotten so much attention recently?

High intensity interval training combines short, high intensity bursts of exercise, with slow, recovery phases repeated throughout one short 15 - 20 minute session. It’s done at 85–100 percent of one’s maximum heart rate rather than 50 -70 percent in moderate endurance activity. HIIT can be done anywhere, doing any type of exercise, and is best described as working out like a “sprinter” rather than a “marathon runner”.

“What’s great about this type of training is that anyone can do it!” -Dr. Josh Ax

The benefits of this type of training have been numerous…

Anti-Aging

According to research, there is a direct relationship between physical activity and life expectancy. Exercises release an enzyme called telomerase, which has been coined as the anti-aging enzyme. When a person works out, this enzyme is released in circulating cells. HIIT training increases high levels of this enzyme which is reflected as…Increased Energy, Increased Muscle Tone, Reduction of Body Fat and Increase in Confidence.

Balancing Hormones

HIIT also helps balance hormones responsible for unhealthy eating habits resulting in weight gain. Two important hormones, Leptin (long term regulation of energy balances and suppresses food intake) and Ghrelin (responsible for feeling hungry) are moderated by this type of training. By balancing both of these hormones, Ghrelin is suppressed and Leptin is increased, allowing participants to manage a healthy weight loss with exercise.

Elevated levels of Testosterone

Elevated levels of Testosterone are detected during and after HIIT, which aids in weight loss.

The new discoveries with this type of training make it very attractive to the normal individual who has very little time for exercise. However, HIIT isn’t just for the beginner. Athletes find this type of training favorable when in conjunction to their sport-specific workout routine.

Studies show that HIIT works better if done first thing in the morning. By exercising on an empty stomach, glucose tolerance and insulin sensitivity improves. This will curb the munchies and the desire to eat unhealthy.
