Ever felt supremely fit but wondered, “Why do I gas out in a fight?”

I recently had a coaching call with a fighter who experienced exactly this. Despite being in the best shape of his life, he found himself exhausted after just three rounds.

It wasn’t his fitness level – it was his fight strategy and work-rest ratios.

Many fighters make three common mistakes:

• Work too long without adequate rest
• Rest too long and lose momentum
• Or (most commonly) have no strategic approach to their output at all
