Exercise, The Fountain of Youth

For years now exercise professionals have been touting the benefits of High Intensity Interval Training, popularly referred to as HIIT.  Studios around the globe have picked up this sensation as a way to maximize time in the gym, reduce body fat, and enhance cardiovascular efficiency.

More recently, attention has turned to brain health and cellular aging, in particular the effects of different types of training on each. Certainly not shocking is that HIIT reigns supreme in this area as well, prompting researchers to call HIIT the new fountain of youth. 

As we age, mitochondrial function (the energy power house for our cells) declines. When our cells lose energy, we lose energy, and our systems become less efficient over time.  Some of this process we label as “aging”, a process that most of us would probably rather prevent!  

HIIT workouts increased Mitochondrial function by approximately 55% in a mixed demographic group.  HIIT training also increased BDNF (Brain-derived neurotrophic factor), one of the most important proteins for brain function.  


  • HIIT can prevent your cells and your brain from aging

  • As little as one single session is beneficial 

  • You don’t have to go hard each time, slight shifts in intensity is also beneficial

  • Workouts can be done in small increments of time, benefits from just a few minutes (jumping jacks in the office anyone?)

  • You don’t need a complicated fitness program to incorporate HIIT into your fitness routine


After warming up for a few minutes, work hard for 30 seconds, then rest for 90 seconds. Repeat this as time or energy permits.  Need more ideas? I’m an email or phone call away!
