No matter what type of workout you’re doing, add a resistance band to the mix, and it’s guaranteed to make it harder. But add eight of them at once? And, well, you should probably avoid making plans that involve walking for at least the next two days. This is exactly the principle behind Agogie Resistance Training Pants ($130), which feature no less than eight built-in resistance bands, and put every other pair of leggings I own to shame.
Unlike regular resistance bands, which only work in one direction, the bands contracted every time I moved my legs—no matter which way they were going. And man oh man, did that make the moves harder.
