The health benefits associated with resistance training are not under debate and include decreased gastrointestinal transit time, reduced risk of colon cancer, increased resting metabolic rate, improved glucose metabolism, improved blood-lipid profiles, reduced resting blood pressure, improved bone mineral density, pain, and discomfort reduction for those suffering from arthritis, decreased lower back pain, enhanced flexibility, and improved aerobic capacity. What has been under debate is how to do it best. 1 The American College of Sports Medicine, long considered the expert in resistance training, has dispensed poor advice over the years, largely unsupported by rigorous science.

In 2011, researchers used existing studies that employed rigorous science to more fully understand how we should work out. They included intensity, the number of repetitions, the length of training sessions, the volume of work, whether core exercises were as important as we think, the speed of repetitions, rest time between sets, and whether free weights are better than machines. Their findings might surprise you.

Sarcopenia: A Common Yet Avoidable Health Problem

Sarcopenia is a condition that starts in our forties characterized by loss of muscle, strength, and stamina. Unfortunately, 10% of the population over the age of 60 have it. It starts slowly, and the rate of muscle loss can reach 15% per year in later years. It typically progresses until 50% of muscle mass is gone by our eighth decade. Since muscles account for 60% of our total mass, this condition can result in serious weakness and other health issues. Although the effects may be noticeable early, they can lead to increased hospitalizations and nursing home care, and early death with older age groups. The good news is that it can be avoided with proper lifestyles. Read on for more information.
