Brandon Kirsch I moved to Dallas two years ago not knowing a soul, and Diesel quickly became my sanctuary. I trained with Justin and Marlon—Justin and I focused on classic bodybuilding-style compound lifts, while Marlon worked with me on stretching, muscle manipulation, and physical therapy-style prep that set me up for success.
Every session was the perfect mix of pushing myself as hard as I could while also having real conversations about life. It’s rare to find trainers who not only help you grow physically but also become genuine friends. That’s exactly what makes Diesel special—every single trainer cares deeply about your well-being, your progress, and pushing you in just the right way.
Shoutout to Josh for the way he trains his clients, Grove with his meticulous attention to detail (and that legendary composition notebook), and D, who pours everything into his people. Across the board, Diesel is filled with trainers who are invested, welcoming, and excellent at their craft.
The gym itself is spotless. Sure, the weights and machines have some character—but that’s part of Diesel’s charm. It’s hands down the best gym I’ve ever trained at, in Dallas or even back when I lived in Austin. I’ll miss it terribly as I move back, but I can’t recommend Diesel—and especially their personal training enough.
Will miss all you guys!
