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.

It all begins with a series called The Numbers Don’t Lie. Five of them, to be precise. Five instruments. Five readings on the panel of the life support system you have been running, without checking the gauges, for most of your adult life.

First Be a Good Animal — PART 2 — Train Smarter

The dashboard shows you the reading. Part Two is about what you do with it.

Six protocols. Each one addresses the instruments directly — moving the numbers, supporting the adaptations, and creating the conditions in which the body can do what it is built to do when given adequate stimulus, adequate recovery, and adequate respect for what it actually needs.
