A lot of fitness advice assumes you have a clean hour, a gym, and the motivation to use both. Real life rarely cooperates.

The good news is that physical activity does not have to happen in one long session to matter. Public health guidance is clear that adults can break activity into smaller chunks throughout the week and still work toward meaningful targets.

A $100 budget isn’t much in the world of fitness equipment—but it’s more than enough to build a smart, useful home gym.
