I'm a fitness writer who swears by Pilates and I think this piece of equipment is the best alternative to reformer classes—and it costs less than $10

You might have heard about reformer Pilates, but chances are there isn’t a class available in your area yet, or maybe there is but it’s very expensive.

Worry not, I’ve found a way to recreate this style of exercise at home so you can experience the benefits of reformer Pilates, such as improved coordination and mobility, better flexibility and posture, and even injury prevention.
