Is High Intensity Training the Fountain of Youth?

Of course you’d expect me to say so, but science has uncovered some compelling evidence that backs me up:

  • Exercise triggers mitochondrial biogenesis, a decline of which is common in aging; this reverses significant age-associated declines in mitochondrial mass, and in effect, stops aging in its tracks.
  • Aside from impacting your skeletal muscle and fat tissue, researchers noted that exercise induces mitochondrial changes that may also benefit your liver, brain and kidneys.
  • One of the best types of anti-aging exercise is high-intensity interval training (like X Gym), which boosts your body’s natural production of human growth hormone, a synergistic, foundational biochemical that addresses the serious muscle loss and atrophy that typically occurs with aging.
  • Longevity is the result of an overall healthy lifestyle and exercise is of course, a key component.
  • Telomeres are the little caps on the ends of your chromosomes that keep them from unraveling and shortening, which causes aging. Stress is one of the top factors in degrading these telomeres. High intensity exercise happens to be the best antidote for stress.
  • Physical exercise, more than mental exercise, protects your brain against age-related changes; people who engaged in the most physical exercise showed the least brain shrinkage.
  • Exercise, diet, and stress management are three primary factors that play key roles in maintaining sharp mental function as you age.
  • Exercise promotes brain cell regeneration and production of key brain chemicals and growth factors such as BDNF, which is important in maintaining memory, skilled task performance, and overall cognitive function.
