Testosterone is an androgenic sex hormone produced by the testicles (and in smaller amounts in women’s ovaries) that is typically associated with “manhood.” Beginning around age 30, a man’s testosterone levels begin to decline, and continue to do so as the years go on.

A wide range of chemical exposures, including prescription drugs like statins, can also have an adverse effect on your testosterone production…

Not long ago, researchers studied the heart health of a group of very fit older athletes — men who had been part of a national or Olympic team in distance running or rowing, and runners who had completed at least a hundred marathons. The results were unsettling — half of these lifelong athletes showed evidence of heart muscle scarring…

A little over three years ago, I was introduced to high intensity interval training, commonly referred to as HIIT, when I met Phil Campbell at a fitness camp in Mexico. I refer to it as Peak Fitness Training.

Since then, researchers have repeatedly confirmed the superior health benefits of HIIT compared to traditional and typically performed aerobic workouts…

If you ask just about anyone what their main fitness goals are, flat, toned and defined abdominals is usually at the top of their list. However, from a fitness standpoint, the aspiration for the “perfect set of abs” should be balanced with the type of training that will best enhance the overall strength of the entire core’s function.

The intermittent fasting approach has been getting increased recognition these days. But 10 years ago, it was a different story.

When I introduced The Warrior Diet concept about 12 years ago, it was highly criticized by mainstream fitness authorities as an “extreme and dangerous” approach to dieting. Telling people to skip breakfast and lunch was like committing dietary heresy…

Increasing physical frailty as you age is commonly accepted as “a fact of life.”

Until recently, most studies showed that after the age of 40, people typically lose eight percent or more of their muscle mass with each passing decade.

But newer research suggests that this is not a foregone conclusion.

One recent study of 40 competitive runners, cyclists, and swimmers, ranging in age from 40 to 81, found no evidence of deterioration…

A new study suggests that exercising in the morning, before eating, can significantly lessen the ill effects of a poor holiday diet.

Researchers recruited healthy, active young men and fed them a bad diet for six weeks. A group of them that exercised before breakfast

I’d like to set the record straight regarding pre-workout nutrition. This is a tricky topic that requires a short biological and science overview, so bear with me.

A growing body of research indicates that nature selects underfed species for extended life-span and vice versa – it shortens the life expectancy of overfed species. Humans are no exception. The human body evolved to thrive under nutritional stress…

Have you tried doing standard cardio workouts faithfully, yet found you still haven’t reached your fat loss goals? I believe that interval cardio, is the 30-minute fat loss solution! I have used it almost exclusively for my personal fitness routine for the last 14 years. Most of my clients perform their interval workouts on a treadmill.

Because it works so well for me, I have had 95 percent of my personal training clients use it too, with great success…

Mounting research suggests that even if you exercise regularly, you might still succumb to the ill effects of too much sitting.

For example, a study published last year1 concluded that adults who spend an average of six hours a day in front of the TV will cut their life expectancy by nearly five years, compared to someone who does not watch TV…
