Muay Thai Q&A – Injuries, Muscle Building, Food Intolerances


Mariusz posed a few questions, wanting to know about common injuries in Muay Thai training (not fighting) and what to do to check and correct the causes; muscle building (hypertrophy) training for Muay Thai fighters; and eating allergies/intolerances.

So here’s another dog-walk talk, where I take the opportunity to chat through some ideas while out walking Logan (my somewhat crazy Tamaskan ‘wolf’ dog). He does his usual stupid stuff, while I try to answer these questions during a frosty, January Sunday morning walk.

I hope you enjoy, and if you have any questions of your own, please let me know.

And here’s a few links that I mentioned in this video too:

Preventing Common Muay Thai Injuries: Lower Back and Knee Pain

The most common injuries in Muay Thai training aren’t from getting hit – though that’s certainly part of it – but from how you move. Most often, knee and lower back issues arise because of poor hip control. When your hips aren’t doing their job, your lower back and knees pick up the slack, leading to pain and injury.

  • Why It Happens: When you’re not properly extending your hips during kicks, that extra movement ends up in your lumbar spine, causing lower back pain. Similarly, if you’re not externally rotating your hips effectively, your knees can collapse inward, placing strain on them.
  • What You Can Do: Focus on exercises that improve hip control. One of my favorites is the Cook Hip Lift. It’s both diagnostic and corrective – helping you identify weaknesses and fix them simultaneously. I’ve got a video on this coming up, so stay tuned.

Building Muscle Without Sacrificing Your Muay Thai Skills

You’re planning to hit the gym and Muay Thai three times a week – that’s solid! But if you’re thinking about a basic bodybuilding routine, let me stop you right there. Bodybuilding exercises won’t serve your Muay Thai needs; they’ll build muscle, sure, but not the kind that improves your performance in the ring.

  • Why It Matters: The muscle you build in bodybuilding doesn’t necessarily translate into better kicks or punches. You need to train movements that are functional and specific to Muay Thai.
  • What You Can Do: I recommend sport-specific compound movements that not only build strength but also reinforce the skills you need in Muay Thai. I’ve shared a couple of routines on the website – Routine A and Routine B. These are designed to keep your body balanced and reduce the risk of injury. Rotate between them to ensure you’re hitting all the right muscle groups.

Navigating Food Allergies and Intolerances: Listen to Your Gut

Gut health is crucial, not just for overall well-being but also for your performance in the ring. Food allergies and intolerances can hold you back if left unchecked. So how do you figure out what’s messing with your system?

  • Why It’s Important: Many fighters don’t realize how much food affects their energy levels and recovery. Common culprits are gluten and lactose, which can make you feel sluggish or give you headaches. I learned this the hard way after cutting carbs before a fight and then reintroducing them. Some made me feel great; others left me feeling hungover.
  • What You Can Do: Start by eliminating potential problem foods, like wheat or dairy, for a while and then reintroduce them gradually. Pay attention to how your body reacts. If you’re still unsure, it’s worth getting a professional allergy test from your doctor.
