First, Be a Good Animal.

First, Be a Good Animal: The science and philosophy of aging well for adults 50+.

Strength, longevity, and the joy of moving like a good animal, from a 74-year-old trainer still in training.

This is a collection of articles written by Marty Trussell, NASM-CPT, Founder of VirtaFitness. Part science, part memoir, part philosophy. This is a blog for anyone who wants not just to slow the decline, but to keep building.
