Most of my home gym equipment is adjustable. Not only can I change the weights, but I can use each part for multiple purposes. The Adjustable Kettlebell in the above photo is a perfect example.
The 15 Inch Long Dumbbell Bar is one of the precision pieces we sell, that is actually a new option as a “Long Dumbbell Bar”. It is actually milled a true round and perfectly fits the Allen Collars. One of my customers actually came up with the idea of using the Allen Collars next to the Kettlebell Handle. It allows you to center the handle and quickly change weights, but it does something more, which is why it belongs in the “Reason for Precision” series.
The Kettlebell Handles are a cast iron piece that has a lot of contours. The contours make it visually appealing and more comfortable, but can make for sloppy plates. If I am doing limit lift work, I don't want slop in my plates. A little jiggle can be be nice to look at, when it's a pin-up in the man cave or garage gym, but keep it away from my one rep max lifting equipment. The Allen Collars will solve many of your sloppy plate issues, because you can cinch those plates right up to the collar and tighten everything down nicely.
You will notice that I used the classic Red Wrenchless Screw Type Collars on the outside of the plates. Generally, I would use Allen Collars there as well, except when I'm training at home. At home, each piece of equipment serves multiple purposes, so I have only one pair of kettlebell handles there. When I want to adjust the weight, I want to do it quickly. Speed of adjustment is the one down side of the Allen Collars. While they hold far better than any wrenchless screw collar, I want my workouts to be fast and efficient. I don't have all day to lift.
All the best,
"Today is a good day to lift."
