If you’re over 40 and still training like you did at 20, mate, you’re probably doing the wrong sort of training. In this video I break down the 3 biggest mistakes that destroy your boxing after 40—and what to do instead—so you can keep improving, avoid injuries, and actually enjoy training again. When I made these changes, I didn’t just feel better in the gym…I got in better shape, started loving training again, and I even set a Guinness World Record on my 40th birthday for the most punches thrown in 24 hours. First, I tell you to stop head sparring. There’s no reason to be getting punched in the face at this age, because even “light taps” chip away at your brain over time. I explain why I switched to shoulder and body sparring to keep it competitive without the long-term cost. Second, I show you why you need to stop judging a good session by how wrecked you feel, and start training with intention—80–90% effort, round-by-round goals, and leaving the gym feeling sharp. Third, I talk about what scared me after my brain scan in the Cleveland Clinic fighter brain study, and why recovery habits outside the gym—sleep, food, sauna, and lifestyle—are half the battle after 40.
