Why Do I Gas Out in a Fight When I'm Fit?

Ever wondered "Why do I gas out in a fight, when I felt so fit?"

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
