Chains can get a bit of a bad wrap because they make lame exercises look hardcore. Wrist curls with CHAINS, bro! Chains don't make bad exercises good. But, there are a few exercises that chains work extremely well with. Lunges are one of those exercises. Doing lunges with chains means that not only do you look like a beast, but you also don't have to hold dumbbells or a bar on your back! It's a win-win.
