Boxing and mma mistakes are easy to spot when untrained fighters rely on aggression instead of technique. In this video, Olympic boxer Tony Jeffries breaks down Death Sentence vs Zachcray MMA fight, a viral MMA street fight filled with wild punches, no stamina, and nonstop trash talk. Two untrained fighters go at it in a scrapyard, gas out fast, and make just about every mistake possible. Tony breaks down what’s going wrong and explains how basic boxing fundamentals apply in situations like this.
How to Throw a Punch in a Fight

Tony’s commentary highlights common beginner mistakes seen throughout this MMA fight, including swinging wildly without balance, not turning the hips to generate power, dropping the hands, looking away during punches, and failing to punch through the target, which results in weak, ineffective strikes. He also explains how poor conditioning causes one fighter to burn out early and why small improvements in technique and cardio matter.
Key lessons from this fight include:
Poor punching form: Big swings without technique waste energy and produce very little power.
Lack of stamina: Going all-out without conditioning leads to fast exhaustion.
Defensive mistakes: Dropping the guard, closing the eyes, and turning away leave fighters wide open.
Whether you’re into boxing, MMA, or fight analysis, this breakdown shows why technique and preparation always matter. If you’re learning how to box, this video is a clear example of what not to do and why proper fundamentals make such a difference.
