Refilling the fast-energy tank

Creatine

A compound your body already makes and stores in muscle to rapidly recycle ATP, the fuel for brief, intense effort.

Example

A few extra reps or a slightly heavier last set — creatine tops up the energy system used in the first several seconds of hard work.

Myth

Creatine is a steroid, or it damages the kidneys.

Reality

It’s not a hormone or steroid, and in healthy people typical doses are well tolerated across decades of research. The main visible effect is a little extra water held in muscle.

The 'loading phase' is optional — a steady few grams a day reaches the same muscle saturation within a few weeks, just more gradually.

Recall check from the same lesson

Creatine's main effect is topping up the energy system your muscles use in the first seconds of intense effort.
