There’s a longstanding school of thought that weight training isn’t the best idea for a combat sports athlete. Good striking mechanics require a flexibility and fluidity of form that excess muscle mass can hinder.

As a 5’ 10” current heavyweight (following a recent weight miss), Knight has some room to bulk up in order to compete with his divisional peers. And in a couple of videos posted to his social media accounts, the Thornton MMA talent showed off the product of his extra strength and conditioning with the kind of bench press and squat numbers that would make any powerlifter proud.
