Query: Great deal

Wayyyyyy cheaper than getting these at the store. They work great and last a long time. I love the door attachment. Just be sure to double check that the door seal is tight, especially when attaching it to the bottom of the door.For ideas, you can always use YouTube, but these are great for anything you'd use dumbbells for.I use them for Tabata exercises. If you don't know what that is... find out!!
