fighting-fit

In peak condition

Fighting-fit means in excellent physical condition, ready for strenuous activity or competition.

The phrase comes from boxing and military contexts, where peak fitness determines survival.

It now applies broadly to anyone in top shape: After months of training, she's fighting-fit again.

The hyphen is standard but sometimes dropped.
