According to articles on and the New York, drinking from the Fountain of Youth could be as simple as getting to a CrossPIT class. “Exercise, particularly high-intensity interval training, encourages your cells to make more proteins to feed their energy-producing machinery — and this arrests the aging process, according to a new study published Tuesday in the journal Cell Metabolism,” says the article on

 Dr. Sreekumaran Nair, senior author of the study and a diabetes researcher at the Mayo Clinic in Rochester, Minn., noted in the article that high-intensity interval training (HIIT), in particular, is “highly efficient” when it comes to reversing many age-related changes. CrossPIT is just this kind of training.


“It seems as if the decline in the cellular health of muscles associated with aging was “corrected” with exercise, especially if it was intense, says Dr. Nair. In fact, older people’s cells responded in some ways more robustly to intense exercise than the cells of the young did — suggesting, he says, that it is never too late to benefit from exercise.” explains the article on The New York
