Extra Carabiners

I am new at using bands, so have little experience onwhich to judge. I have been using dumbbells and will continue with them and will augment with bands,

Works well but I don't use the door to hold this much pressure. I installed "Bob & Brad's wall anchors" along the door frame. They are rated to 800 lbs so the small weight used is no challenge for them. The door strap fits through the center hole.

These are super strong, solid carribeaners at a good price.
