Your Cells Have Hundreds of Tiny Batteries Working for You

Every cell in your body holds 300–400 mitochondria, and the most demanding ones (like brain cells) can hold thousands. These tiny “batteries” fuel everything from movement to memory.

When they work well, you think clearer, recover faster, and feel more capable in your body. When they’re stressed, everything downstream suffers.

Strength training boosts mitochondrial efficiency: another reason simple, effective training matters.
