These are resistance bands with handles for working out. These exercise bands come in 10, 20, 30, 40, 50 lbs so you can tailor your work out at home to your needs. You can use the bands independently or in any combination with a maximum resistance level of 150 lbs. Great for taking your exercise plan with you while traveling without needing to bring dumbbells. Comes from smoke free and pet free home. I live in Saint Michael just south of the Albertville Outlet Mall which is west of Maple Grove on I94.
