I went there and was told to hit 100 burpees before I even entered into the room. At that moment, I knew I made a grave mistake. Yet, I already drove 80 miles and I couldn’t let my gas money go without fruition. I survived but this gym is no joke. All I can say is pray to whatever spiritual force you believe in because nobody will save you.

Questionable workout methods, but ig unc knows best. I had a wire on me from the feds, and when unc found out, I had to use my phone because the wire was scaring him. He then uttered the most magnificent word ever to be heard by a human ear. “Hey pops, el wiro”. We then had to run to the hill after our 50 burpees. Would absolutely recommend. P.S - Do NOT drink Gatorade in there. You’ll thank me later.

Unc put me through the ringer. I got in the gym and he told me part of the initiation fee was 300 burpees, I could barely breathe after but before I could ask him anything he told me to hit the hill. Man, I guess he forgot about me out there and I ran for multiple hours being passing out. I woke up shaking, dehydrated and confused. Guess who was there, it was Unc. Because my eyes closed when I passed out he told me to hit a 200 count on a 3 plate bench press. Keep in mind, I can only bench 195. After one rep the bar snapped my neck when I dropped it. I heard someone say "I'd rather die" in the back. In that moment I thought I died. But man, what an experience.
