Descrizione

Are you wondering whether it’s safe to train Brazilian Jiu Jitsu when you’re sick? Maybe you’ve got a cold, sore throat, or cough and you’re tempted to push through and make it to class. In this video, I explain when it’s okay to exercise, when you should stay home, and how to return to BJJ safely after illness.

I’m Marc Barton – black belt, full-time instructor, and former emergency medicine doctor. In this video, I break down the risks of training while sick, both for your own health and for your training partners, and share practical, evidence-based advice on what to do instead.

What you’ll learn:
✅ Why training while sick can delay recovery
✅ The risks of complications such as pneumonia and myocarditis
✅ How illness can spread rapidly through a BJJ gym
✅ Safe alternatives to training when you’re unwell
✅ When it’s safe to return to drilling and sparring

This video is for anyone who trains Brazilian Jiu Jitsu, grappling, MMA, or any contact sport and wants to make smarter decisions about training and recovery.

Who this video is for:
• BJJ practitioners of all levels
• Grapplers recovering from a cold or flu
• Coaches and gym owners
• Anyone interested in training longevity and injury prevention

The short answer? If you’re genuinely unwell, rest. You’ll recover faster, protect your teammates, and get back to training sooner.
