Can I Reach PGA Tour Swing Speed Ep 2 | TheStack System!

Welcome back to Episode 2 of the “Can I Reach PGA Tour Swing Speed? Winter Speed Challenge” 🏌️‍♂️💨

In this video, I’m jumping straight into a live training session using The Stack System — showing you exactly how I train to gain speed and how the system tracks progress.

We’ll take a deep dive inside The Stack app, exploring:
📊 The key data it collects during each session
⚙️ How it analyzes your swings to suggest personalized training protocols
📈 What my current numbers look like halfway through a protocol
🔁 How I’m restarting training after a few weeks off

If you’ve ever wondered how The Stack System actually works or what speed training looks like in real time, this episode breaks it all down.

My goal remains the same — reaching 167+ MPH ball speed, putting me right in line with PGA Tour players like Russell Henley and Brian Harman.

Hi everyone and welcome to episode two of can I reach PGA Tour swing speed win winter speed challenge. In this episode we will take a look at the stack system for speed training and complete a return to form session. If you missed the first episode and what this is all about, you can find that here. I’m Graeme. Now let’s get stacking. So, as you can see here, the stack system consists of what is basically a golf club about the size of a hybrid with a screw thread at the end and obviously the bright yellow holder. And inside this little pouch, there are a bunch of weights. And the weights are 100 g, 75 g, 60 g, 45 g, and 20 g. And multiples are used each session. Okay. So, we’re going to jump straight into the app here and we’re going to head to special session. And at that point, we are then going to be selecting a return to form and then just setting it to start. That’s going to then link up to our launch monitor. And we’re pretty much ready to go. Prepare for set one with 195 g. These are full effort swings. Swing one was 91. E speed is 100. Distance potential is 269. Swing was 91. E speed is 100. Distance potential is 269. Swing three was 90. E speed is 99. Distance potential is 266. Swing four was 93. Especial is 276. Swing five was 90. DP speed is 99. Distance potential is 266. 36 was 94. EP speed is 104. Distance potential is 279. Swing seven with 93 speed of 103. Distance potential is 276. Swing 8 was 92. E speed is 101. Distance potential is 273. Review set one swings. Then prepare for set two with 240 grams. These are full effort swings. Heat. Heat. Now’s a great time to subscribe so you don’t miss anything in this series and any other exciting content that I’ve got coming up in the near future. Okay, so now you’ve seen what a return to form session looks like. Let’s have a little bit more of an in-depth look at the app itself. So, obviously you can see across the bottom there, you’ve got the options for speed training. There’s also a new wedge training function, but I believe that requires a special radar. There’s a putting solution, which allows you to practice your putting out on the putting green and record some data. Obviously, some learning functions and a main menu. If you look then at the general screen, you’ll see from the top that obviously within this protocol that I’m running, you’ve got my highest stack speed today at 102, which equates to a driver E speed of 112. Now, you got to bear in mind that this is full out trying to just swing it as fast as possible. So, it’s not really a playable speed on the golf course at that current point. That’s giving me a distance potential of 304 based on a normal temperature and where I am based at about sea level. The grit score is basically how regularly you’re performing. So obviously if you’ve doing your speed training as you should do, then expect that to be nice and high. If you’re missing lots of sessions and not doing as you’re supposed to, that will gradually drop. So if you then look under the distance potential and grit score area, you’ll see separate sections where you can share your progress, the special session, one of which we’ve just done today, any completed sessions, you can change your program at any time, and then completed programs. and we’ll have a look at that very shortly. You can see underneath that then that there’s the full speed spectrum and you can see that I’ve already done 11 of 24 sessions completed. Now, like I say, I’ve had a little break, hence why I’ve just done that return to form session and then I’ll be beginning the speed training again and I’ll expect to start that in the next couple of days as per the schedule says there to say I need to start it Friday, Saturday or Sunday. So from that point there, what we can do is we can have a look at what the data is actually recording across some swipe screens. So if I just swipe across on the app here, you’ll see that this then gives you your training speeds for the protocol that you’re doing at the moment. And you can filter that by what speed you want. You can filter that by your intent, which is full, which is what we’ve been doing in the return. So that’s a full swing, as in if you were going to hit a hard golf shot on the golf course, but try and keep it in play. You’ve got max, which is what we will be doing as we go through the training session, which is basically all out power. We’re not worrying about what the swing looks like or what would happen if ball was in the way. We’re just swinging it as hard as we possibly can. And step, which is a max swing, but with a step forward during the swing. So, think of it a little bit like a mini Happy Gilmore. So, then obviously if we were to scroll across again, you’ll see the personal best speeds from this set of protocols. And this is marked out by the weight that you’ve been asked to swing. So, as you can see there, 195 g at 102. Now, 195 g is the main metric that the stack uses for a reference to swinging a normal driver. And you can see that I’ve obviously been up at 102 at the moment, and I would hope to obviously begin to increase that. If we then scroll across another page, you’ll then see what they call the driver E speed. So that’s where they take the calculation of the 195 g stack swing and they then put that into their system that brings up a driver head swing speed. And obviously you can see that I’ve been hovering around 109 110. The last session before I took my little break, I managed to get up to 112. And again, just remember these are full out maxed swings. So there’s no potential really at that point to hit that on the golf course. I’m looking at dropping sort of down to 108 or so at the moment um for actual playable golf swings on the golf course. And again, you can then see that they’re then creating a distance potential, which is how far they’re suggesting that they think that you can hit the golf ball given the temperature and the altitude that you’re actually playing at. And you can see that’s obviously including with roll out. So it says that if I could manage to get to 112 head club head speed, then I would have the potential to hit the ball 304 yards on a regular basis. We then come into the grit score. And again, as I mentioned, the grit score is basically a way of motivating you to continue to follow your progress and continue to do the work. And obviously, you want that number to be up as high as possible well into the ‘ 90s. And then you’ve got the health and energy, which you saw me put in on the back to form session. And that’s pretty much about it. So if we then take that back to home, we can then have a look at what I’ve been doing and how I’ve been progressing through here. So if I click on completed programs, you can then see that my speed training programs all appear as per when we started. Now you can see that I started in February 2024 and that my first starting speed with my driver was 97 mph. And you can see in that first session I gained quite a lot. Now I was a little bit quicker than 97 mph before that but I dropped some swing speed. So I was keen to get that back to 103 104 where I had been but I obviously also picked up a little bit in that. Now you can see then when I went into my second session which is my full speed spectrum. You can see then in that through that protocol I gained a couple of miles an hour extra. The next one I gained a couple of miles and extra, but then you’ll see I had a drop and that was last summer where I had a back injury and I was out of golf for around about nine weeks. So I couldn’t do any physical activity particularly. Couldn’t play golf and certainly couldn’t swing speed train for a good 10 to 12 weeks. But you can see then that as I gradually got back into it, my speed’s gradually increased again. And my most recent ones have been about 110, but I’ve kind of plateaued over the last couple. So I’m keen to see if we can again just push on. So that’s basically what the app does. So as you can see here from this screen, the start of each new protocol, you’ll be asked to create a baseline and you can see that from here where you have to swing the driver as if you were out on the golf course and then you have to swing the specific weights in the way that they’re shown there. That then provides the information where then the stack system goes away. It checks how you’ve done this time against last time and then puts that all into the system and produces a training regimen for you. Now, as you can see, I’ve been doing full speed spectrum all the time, which is the recommended protocol for me. But each one of those four speed spectrums is actually slightly different. So, the weights are different and the way it works is slightly different. So, it’s really interesting that it’s picking the data, looking at what we’ve gotten there. So if I then just go back to there, you can see then that at the end of a protocol, you also then do a progress check. And that then will check that against your baseline of where you started at to see where you’ve gained speed if you have and that will then form part of the analysis which will then produce the next session that it suggests for you to do the speed. So, in essence, it’s basically looking at the data you’re producing, looking at how quickly you’re improving, baselining that against other players that are doing the same thing, seeing what’s making them progress better, and then suggesting protocols that it thinks are going to be better for you. So, all in all, it’s quite an encompassing app. Also, additionally, it links to my launch monitor, which is a Flight Scope Meo Plus. Obviously, if you’d like me to show you more of that or give you a review on that, then stick me down in the comments. That allows me then to automatically capture this data. So, there’s no manual keying for me. And I find that really, really important and really useful. I can just make my swing, the launch monitor records the information, the stack picks that up, and obviously all my data is recorded. So, I don’t have to worry about any keying or anything, which is really, really great. It’s a system that I’ve been using, as you can see, now for more than 18 months. I’m not sponsored by the stack. This is a system that I purchased and also I pay a subscription for each year to maintain its service. But I’m quite happy with it. Hopefully you’ve now seen it in action and hopefully you can see the sort of work that I’m going to be doing to try and increase my swing speed over the winter and get myself up to PGA to a standard. So what happens now? So now I begin my speed training trying to do two to three sessions every single week. And at the end of each week, I’ll produce a YouTube short that will explain what I’ve been doing and how I seem to be progressing on that week. Additionally, each month, I’ll be producing a fulllength video, giving you a full update, having another look at the app, and seeing how I’m progressing, so we can see whether things are going well or if I’ve had any issues. It’ll be great to hear from you guys as to if there’s anything that you’re doing over the winter around your golf. Are you going to speed train? And has this video helped you to get an idea of things that you can do? or perhaps you’re going to be doing some technique work. But pop that down in the comments. I’ll be pleased to see what everybody’s up to. So don’t forget to like, subscribe, and leave a comment down below. And if you missed any of the series, you can catch it right here. I’m Graeme, and I’ll catch you on the course soon.
