Have you ever wished for the versatility to exercise indoors and outdoors with resistance bands? I know I do when I want to exercise; I want to use horizontal movements instead of always doing vertical activities. The problem is that no door anchor on the market has the versatility I needed. That is until I found the Undersun Universal Door Anchor that allows the use of indoor and outdoor exercise. This article will explain why this door anchor is the best and how it will benefit your long-term workouts.

What is a resistance bands door anchor?

A resistance band door anchor is a piece of apparatus to perform horizontal and vertical exercises with resistance bands. It has a round foam placed on the back tail of the door anchor. Theirs a loop where you can wrap the resistance bands. You can put the door anchor above, below, or laterally on the door. You must close the door to keep the anchor sturdy when pulling the elastic bands. The Undersun Universal Door Anchor was designed by James Grage. Here’s a link to read about him.

How do you use the Undersun Universal Door Anchor?

Place the strap between the door edge and frame to use the door anchor correctly. The final step is to lock your door so that the door won’t open. I suggest you place the round foam outside the door and the loop on the inside. I say this to ensure your safety comes first and the door doesn’t open.

Another way of securing the sturdiness of the anchor is to use the straps and wrap them around a two-by-four or a tree. This is in case you want to exercise outside with the resistance bands.

Is the Undersun Universal Door Anchor high quality?

Yes. The Undersun Universal Door Anchor is durable. The material has double-durable nylon, heavy-duty stitching, and strong nylon material wrapped around the foam. It won’t damage your door or door frames. The door anchor is unique from the rest because of its long strap to wrap around a sturdy object. It comes with metal rings to bind the straps. It can wrap around a tree, bench, gate, or two-by-four lumber. Another unique asset of this door anchor is the clear tubing on the loop. It makes it easier to wrap and unwrap an elastic band off the loop instead of a regular one.

What are the pros and cons of the Undersun Universal Door Anchor?

With this door anchor, you won’t have any issues. The plastic tube doesn’t rip because it’s very tough and made from vinyl plastic. The whole body of the anchor has double-layered nylon. I don’t see or feel anything wrong when I use it during my elastic band workouts. I think the time it wouldn’t serve well during exercising is if you don’t practice safety. Suppose you use the door anchor indoors; close and lock the door. If you use it outdoors, wrap the strap in and out the metal rings to make it secure.

How does the Undersun Universal Door Anchor measure up to other resistance band door anchors?

The Undersun Universal Door Anchor is far superior to any other door anchor. All door anchors don’t have double-layered nylon around the body and a plastic tube on the loop. If you wrap a loop band around a regular door anchor loop, the door anchor loop will wear and tear. The nylon wrapped around the foam is another benefit that makes the Undersun far superior to last for years. Also, no other door anchor has a long strap to wrap around a sturdy object to exercise outdoors. So yeah, the Undresun Universal door anchor beats the rest of the competition.

Who is it geared towards in the long run?

The door anchor is for individuals who want to preserve long-term resistance bands training for years to come. I’ve had the door anchor since February 2022. Thanks to the added doubled-layered nylon and clear tubing on the loop side of the door anchor. The door anchor can last for a very long time. You can pull as hard as you want; the Undersun Universal Door Anchor won’t rip. I guarantee that it won’t.
