Strength training
For exercise and longevity
The experts we follow agree on this.
Strength training is a proven way to maintain muscle and support healthy ageing.
Who is behind it
Voices including a former research biochemist, a Princeton-trained molecular biology PhD and a licensed acupuncturist and clinician-educator.
How strong the research is
Mostly expert experience so far, with published research still catching up.
In their words
“strength training and other weight-bearing exercise as a means of improving my health and that to this day I still I'm religious about that because I know it's so important”

Strength training helps increase lean muscle mass and testosterone levels
Building skeletal muscle and getting enough protein is crucial to prevent frailty and maintain independence with aging.
Strength training has benefits but without cardio, cardiovascular health benefits are limited
Muscle is the primary site for glucose uptake, and quality muscle tissue prevents glucose from remaining in the bloodstream, reducing health problems.
Maximal effort with adequate rest optimizes quality of training without chasing fatigue or soreness.
