When it comes to finding the right size tricep rope, there are a few things you need to take into account. The first is the length of the rope. You'll want to make sure that the rope is long enough to comfortably reach your triceps without being too short or too long. The second thing to consider is the width of the rope. A wider rope will provide more resistance and be more challenging to work with, while a narrower rope will be easier to grip and work with but won't offer as much resistance. Ultimately, it's up to you to decide what width works best for you based on your own strength and abilities.
