Jeremy Fernandez is a jiu jitsu brown belt, a father of four boys (two in college, one about to turn 10, and a stepson turning 30), and the owner of JF Woodworking, a one-man remodeling business in the St. Louis area. He's also one of the hosts' main training partners at Watson's.

Jeremy grew up poor in a chopped-up second-floor apartment with no air conditioning until he was 16. That's the year he stood up to his father, grabbed his clothes, and never went back. Wrestling was the first place he felt good at something: he started around 12, used his long, lanky frame for leverage, and won freestyle state as a sophomore. He talks openly about a father who drifted out of his life (the Christmas cards left in the screen door), about becoming a stepdad at 19 without any model for it, and about the things he'd do differently raising his older boys.

From there: custom car audio (where he learned to build), MMA under Jermaine Andre and later at Finney's, walking away from the cage, and finding the missing piece again in jiu jitsu. He breaks down how he competes (a relaxed "it's just a hobby" mindset held alongside an "I'm going to kill everybody" mindset), his exact competition-day ritual, the Dallas Open win over a six-time world champion, and why he stopped making game plans. The back half covers JF Woodworking: learning trades from old-timers, YouTube, and building codes, obsessing over tile, forgetting to bid a $5,500 shower, and a full kitchen/laundry/master-bath gut due by Christmas Eve.
