I weighed the cable carriage and it weighs 15 lbs. From now on, all posts will add the carriage weight to the added weight, resulting in an accurate # for the weight of that exercise. Much of my prior armwrestling cable exercises will have very different weights because I wasnt' counting the weight of the carriage. Some of them are accurate because, at the beginning, I didn't have the cable tower and was using a cable over a bar.
