It is for you if you’re strong enough that you find yourself maxing out any selectorized machine you regularly use during training. And it’s not for lifters that don’t use selectorized weight stack machines. Ultimately, you use any piece of gym equipment at your own risk. Also check the actual pulleys for any damage. It’s a smart idea to inspect your cables regularly for any damage to the sheath or any other part of the cable. However, that happens from long term wear of the cable and is usually the wear is visible. Of course, it is possible for cables to snap even on weight stacks that you aren’t adding weight to. This is because the standard weight rating for cables on selectorized machines is 2000 lbs. Luckily, though, the GymPin is generally safe to use on selectorized weight stacks. One of the most common questions you get with a product like the GymPin is, “Is it safe?” People are concerned about the extra weight causing the cable to break. But if it’s a 2:1 ratio, for example, then the resistance added is half the amount of weight you added. If your machine uses a 1:1 ratio, then weight added does equal resistance added. You have to take into account the pulley ratio. Lastly, it’s important to note that the amount of weight you add to the GymPin is not necessarily the amount of resistance you will add to the cable. Alternatively, some guys will max out the length of the sleeve and have a gym partner keep the plates from sliding off with their hands. You may also need to account for the use of a barbell collar, which takes up space and may be needed in some cases to keep the plates on. If you have calibrated steel plates, which are the thinnest type on the market, you can fit even more plates on. If you have regular cast iron plates, you can fit more plates on. The actual amount of weight you can load onto the pin depends on the number and size of plates you can physically fit onto the sleeve.įor example, if you have super thick crumb rubber bumper plates, you may only be able to fit one or two 45 lb plates on, depending on the GymPin model. It’s unlikely you could fit that much on the medium length sleeves of the Original GymPin and 1″ GymPin.

However, it’s no doubt impossible to fit that much weight on the short MiniPin sleeve. Note that the 10mm versions of the Original GymPin, MiniPin and 1″ GymPin could technically handle the 85kg capacity of the KingPin (which only comes in 10mm). Note: You won’t be able to fit this much on the short sleeve unless you’re using thin calibrated steel powerlifting plates.Depending on the model, people have loaded more than these weights without issue: The GymPin company provides general weight ratings for the various GymPin models. How Much Weight Can You Add to the GymPin? There’s an important reason why I did this, and I’ll discuss it later in the section on compatibility.

You may notice that I’m using 35 lb plates as the largest plates instead of 45 lb plates. It’s important to know dimensions before buying so you can ensure the model you get fits the machine(s) you’ll be using it on.

The Original GymPin (This is the one I own and tested).

I’ll discuss all specs, including unit weight, in the next section. The amount of incremental weight added depends on which GymPin model you have. That is, when you don’t load any plates onto it, it becomes an “adder weight” if you want to add just a small increment of weight to the stack. The GymPin isn’t just for adding plates to a weight stack. The sleeve length depends on which model you get.

A 1 or 2 inch diameter steel sleeve that is molded over the upper portion of the pin/rod.

The length of the exposed portion of the rod/pin is 102mm, or 4 inches long on all models. the pin) that goes the entire length of the GymPin. All of them consist of these two basic components: There are few different models of the GymPin.
