Using the interval training program has really helped my Thai boxing fitness. Fights outside of Thailand tend to be at a faster pace, and the later rounds in Thailand are too. Being able to change pace in a fight, and use the fitness I’ve built is a real advantage.

“I followed your suspension training system exclusively for about a year and it helped my performance tremendously.
Research also says that basically the least important factor in program design is which particular exercise you pick to train a movement or characteristic.
Your program satisfies all the movement pattern and force/velocity curve requirements, so the fact that it is “only” using a suspension system instead of weights is largely inconsequential. It’s a great program. Thanks.”

Meet Your Coach
Don Heatrick
I started fighting at 32. I had no coach, no corner, and no proper ringcraft. By 34 I was selected for England. By 40 I was UK ranked #4, beating fighters half my age.
Before coaching, I spent nearly two decades as an engineer, designing broadcast systems for the BBC and ABC. That mindset never left. I approach Muay Thai performance the same way I approached engineering: find the constraint, apply the smallest effective intervention, test the result.
Over nearly three decades, I’ve coached more than a thousand fighters across 95 countries. I host a podcast, run a YouTube channel, and build evidence-based programs for fighters who train on limited hours and need maximum return from every session.
