Precisely.

And if you're all about optimization and time, you could get a VersaClimber cross crawl club model and spend 8 minutes (2 mins warm up, 4 mins HIIT, 2 mins cooldown) for better (clinically proven more effective at causing a metabolic shift) results.

Why doesn't everyone do this? For one, the intensity makes people ill when not used to it. That's why it's not in many clubs. For another, unlike rowers or cycles, you can't just sit on your butt or coast.

(In addition to road cycles, I own water rower, versa climber, and hydrow. The VersaClimber kicks your ass.)
