Yes, this job affords me the ability to try almost everything. My basement is a gearhead’s dream. However, no matter how many times I get gear, get fit by the best in the world and see how all the soup is cooked, etc., I’m still a 48-year-old, wanna-be-good golfer in decline. So what do I really want for the holidays? To build speed.
I’ve played a few times this year and it pains me to get out-driven by some people, especially when I spent a large portion of my life being the longest hitter in the group.
So what is my big request for Christmas? Something I want and can’t get my hands on? Easy: TheStack speed trainer.

I have had so many friends dig into this and 100 percent of them got faster.
With the sticks and training protocols (and, if you really want to go deep, a radar device to chart speed) TheStack will help you build speed, sequence and flexibility incrementally over the winter. As we all know, players on Tour are getting faster and faster, and this product is of the main things I see trainers use with players. Keep in mind that just getting fast is good, but it’s not the whole story. It’s how you get fast and how you maintain the speed that’s the secret sauce.
TheStack system gives us a plan and a digestible way to build speed across the bag and keep it with simple maintenance. At my age, with two kids and 100-plus travel days a year, I’m not in a position to be in the gym or on the range for hours on end to dial it all in. This system gives me a foundation that’s easy to follow.
So to all of Santa’s helper out there, all I want for the holidays is TheStack. Let’s hit 170 mph in 2026!
