No, a dungeon it's not, but there's no better name for our workout area than a "Pain Cave". Whether it's long rides on the trainer, 500lb deadlifts, or tournament worthy ippon seoi nage throws, this is where pain happens.
Not sure how it worked out, but the ventilation is all hiding in this pic. When I long ride the trainer, the bench comes out of the squat rack, the bike goes in, and two Vornado floor fans keep me cool and dry. A pedestal fan blows over the treadmill to keep it cool as well. I'm not much of a photographer, so it looks pretty cramped, but it's not really: 16ft x 16ft, with 10x16ft open area. Another TV coming soon (Yay Cyber Monday deals!) to put in front of the treadmill. My wife didn't appreciate the partially obstructed view of the TV in the squat rack from the treadmill, ended up getting a 24" Smart TV for free, should be here next week. 1300lbs of weights, heavy bag, treadmill, cycle trainer, grappling dummy, bench, and squat rack. The Concept 2 Rower is outside for now. There's nothing functional or productive that happens at a gym besides swimming that I can't do here.
