We can’t all have a place to exercise (see also Movnat.com) full of boulders, rocks, rivers, logs, trees, forests, trails and splashing oceans waves. We live in varied terrains, and we live near lots of people: in towns and cities. We have to adapt — it’s only human; it’s only what all living things must do in their environments…if they are to survive. So the logical and practical thing to do is to bring such an environment — and the possibility for the motions and movements we evolved to survive — into our cities and towns. We need a “Paleo gym” or “Evolutionary Fitness gym.” The modern gym will need to evolve to follow the dictates of the sciences of evolution, anthropology, (rational) exercise science, (rational) nutrition, body dynamics. No more machines that don’t have pivot points which conform to the human body. Machines are beautiful, elegant, and poetic. But in exercise, man is the measure of all things. In exercise, the machine should fit the person, not the person the machine. Machines should be made so they can be better adjusted to the pivot points and motions of the individual. We could give more emphasis to free weights and things like kettlebells (see also USKettlebells.com), too. Maybe gyms will evolve to have rock climbing in them. And artificial boulders we can jump on and off and climb up. The jungle gym and the associated playground equipment (slides with ladder to climb; balance beam; circular platform that we’d fun alongside, then jump on; swings; etc.) were always attractions on playgrounds; they allowed us to work all sorts of motions and muscles. They were fun and good exercise. Perhaps we need something like that in the gym. And ropes to climb. It would be nice to have logs or sleds to drag around, too. Of course, this all would require waivers of legal responsibility! Caveat emptor.
