Not the barbell. Not the bicycle. Not the rower, the Airdyne, not the pullup bar. I’m talking about the Smith Machine, of course, specifically the squats and curls you can do within its elite confines.
Just kidding. It’s the Versaclimber, folks: the most brutally effective piece of fitness equipment you’ll ever use (but probably haven’t).
Most people don’t know about it because no one talks about it, few use it, and gyms don’t stock more than one if you’re lucky. Is this because it’s a useless piece of machinery? No. The Versaclimber is almost too good, too effective, too intense an experience for most people. The few that have used it almost invariably quit because it’s so hard. And gyms don’t have many because they can’t convince people to use it, to actually go all out like they’ve never gone all out before.
