As adults we lose a little muscle mass each year – up to five pounds each decade. It is part of the aging process. As we age the rate of muscle loss increases. Loss of muscle is the number one bio-marker of aging, and it is vitally important to remain strong and retain muscle as we age.
With less muscle our resting metabolic rate declines increasing our propensity to gain fat. The subjects in this strength training study Strength training increases resting metabolic rate and norepinephrine levels in healthy 50- to 65-yr-old men increased their lean body mass, decreased the body fat, and increased their resting metabolism.
You need not spend hours in the gym to make a profound difference. Studies have shown that significant strength increases result from high intensity interval training as little as once a week.
As you become stronger you will find you will be able to engage in more activities, and this will further enhance your health. It all starts with strength. Just improve a little each week and over time you will feel years younger. High intensity interval training is the type of personal training we do at Austin Fitness Training and at New Orleans Ultimate Fitness.
