STACK System Review: It Stacks Up… BUT Is It Worth It?

Swingspeed or club head speed as it is also called is the key factor for determining a golfer’s potential distance.

Each 1 mph increase in swingspeed can add up to 3 yards (2.7 metres) of distance and the stats clearly show that increased distance directly correlates to lower scores.

So its not surprising all golfers want more of it if they can get it. Including me!

And given the Stack System is a scientifically designed swing speed training program that uses variable weight clubs, app-driven workouts and personalised drills to increase clubhead speed I decided to give it a go to see how much speed I could gain with it.

After only 11 weeks of dedicated training with the Stack System, I gained 3-4 mph swing speed and hit my longest drives 13 yards (11.8 metres) farther, both in carry and total distance, than my previous best tee shots.

But these distance gains came with a clear drop in driving accuracy and consistency that left me questioning whether this premium speed trainer truly is worth it for the average time-poor golfer.

So if you too are wondering therefore whether swingspeed training can help you crack longer distances while fitting into a busy schedule, keep reading for my:

Golfing Focused Takeaways For Time Pressed Golfers

• Swingspeeg Gains Are Real: Delivered measurable swing speed gains for me (3-4 mph in 11 weeks, 13 yards (11.8 metres) extra total and carry driving distance).
• Accuracy Impact: Distance gains can initially lead to wider dispersion and reduced driving consistency.
• Cost Considerations: High upfront costs for club ($338 / £250), required radar device ($338 / £250), plus ongoing subscription ($129 / £95 annually after year one).
• Time Commitment: Requires consistent training sessions (60+ minutes per week minimum), potentially challenging for busy golfers.
• Professional Validation: Proven results backed by pros like former US Open Champion Matt Fitzpatrick; clear benefits if you’re serious and disciplined with your training.
• Is the Stack System Worth It? Ideal if distance significantly outweighs accuracy for your goals, less suitable if you’re accuracy-focused, budget-conscious, or severely time-limited.

Stack System Review: My Hopeful Journey to 300 Yards

My goal was simple: crack the 300-yard barrier with my driver!

Having already gained 40+ yards through driver loft and attack angle changes, I needed the final piece of the puzzle — more swing speed – if I was going to have any hope of reaching my longed for goal.

With my baseline swing speed starting at a little over 100 mph producing drives of 270 to 280 yards (247 to 256 metres) in total distance, I needed to push closer to 110 mph to reach that magic 300-yard mark.

The Stack System seemed like the perfect solution.

Used and commended by professionals like former US Open Champion Matt Fitzpatrick, this data-driven approach promised the swing speed gains I needed through scientifically designed training.

And here were my results after 11 weeks:

	BEFORE STACK SYSTEM TRAINING	AFTER STACK SYSTEM TRAINING
Driver swingspeed	102.5 mph	105.8 mph (+3.3 mph)
Longest Total Driving Distance	280 yards	293 yards (+13 yards / 11.8 metres)
Longest Carry Distance	249.3 yards	263.2 yards (+13.9 yards / 12.7 metres)

So the good news is the Stack System absolutely works for increasing swing speed based on my experience.

Here’s the honest truth the marketing doesn’t emphasize however: there is always a downside of any change as there is with everything in golf.

And for me it was that those distance gains came at a real cost to my consistency resulting in:

• Wider shot patterns
• More poor drives
• Need for additional practice to regain accuracy at higher speeds.

This raises the crucial question every golfer must answer when reviewing the Stack System: Is the extra distance worth the temporary (or potentially permanent) accuracy loss?

To decide that fairly though we of course need to look at the overall Stack System package in more detail.

Is the Stack System Worth It? The Complete Breakdown

The Stack System package itself includes a:

• Variable weight training club with interchangeable weights
• Stack App (free first year, then ongoing yearly subscription is required to keep access to the training programs)
• Personalized swing speed training programs based on your individual stats and goals
• Progress tracking and gamified workouts.

It is crucial to note though that the Stack System and App as sold on the Stack website or Amazon by themselves will not let you complete the training programs in full.

The Stack System training also requires a ‘radar’ that can measure the speed of your swings without ball impact.

On the plus side the majority of standard launch monitors and radars on the market today are compatible with the Stack System.

However not all are.

And although you could of course try to use the variable weight training club without one you’ll not be able to track your swing speed progress to see whether it is making any difference.

I therefore bought the Stack Radar separately to keep things simple and also to ensure I was definitely buying a compatible radar device.

But this of course means yet more cost to get the complete value from the training.

Here’s a list of the items you need and the prices I paid for them in the UK.

• ‘The Stack’ Training Club: $338 / £250
• App (including speed training programs): Free for first year. $129 / £95 per year from year 2
• Speed Tracking Device: Radar or Launch Monitor Device. $338 / £250 for Stack Radar

[Editor’s note – Bundle deals for the training club and speed tracking devices in different countries can be cheaper]

The Training Experience: What the first 11 Weeks Actually Looks Like

The foundation Stack System program requires two sessions per week of 30+ minutes each, including warm-up time.

Miss a week?

You’ll need to complete a “return to form” session to let the app recalibrate things before restarting the program.

And the key training insights from my experience?

• Learning curve: It took me several sessions to get comfortable the concept of swinging at maximum speed without worrying about balance as you would on the course
• Warm-up is critical: Both for injury prevention and achieving your highest speeds during sessions
• Technical issues: Bluetooth connectivity with the Stack radar was patchy, though the dictation feature helps solve this when it happens.
• Focus point essential: I used a knot in my deck wood as a target to simulate me looking at a normal tee on the course or in a golf simulator and I would highly recommend having something to aim at if there’s no tee in front you.

The app’s voice function that calls out your program as you go is also genuinely helpful.

And being able to record notes between sessions proved valuable for keeping track of what worked in an individual session and carrying that learning to the next one.

How Much Speed Can You Gain With the Stack System?

My own 11-week experience provides clear evidence that golfers can expect an increase of between 3-4mph with the foundation program.

But were my results a one off?

Conversations with other users I know, and the results of non-other than a US Open Champion, show this is definitively not the case.

Indeed a friend of mine at my local golf simulator club has recorded even bigger gains than I have through longer term, more consistent use.

Having started the program with a swing speed of 95mph he has now achieved a remarkable 13mph using the Stack System.

And for him this has delivered approximately an extra 30 yards off the tee and at least a whole iron club for his approach shots into greens.

There is also of course the pro flagship user of the Stack System – 2022 US Open Champion Matt Fitzpatrick – who credits it with giving him the distance he needed to win that first major.

Averaging 288 yards in 2019 on the PGA Tour Fitzpatrick used the system consistently over the next 3 years to enable him to add 4mph to his swingspeed and deliver now over 300 yards of distance on average.

Taking about the Stack System following the biggest triumph of his career Fitzpatrick simply stated – “I’ll be honest, it’s worked wonders.”

So while how much speed any individual can realise using the Stack System is of course down to them these examples highlight the key factors that would affect your potential gains:

• Consistency with the program (missing sessions requires restarts)
• Physical preparation (a proper warm-up is essential)
• Time commitment (60+ minutes per week minimum)
• Starting baseline (lower starting swingspeed golfers may see larger gains).

“I say to my amateurs, at least 20 balls a
week, you should be swinging really hard. Really, really trying to push it up there, and
then play within yourself. You don’t have to swing as hard on the golf course, but you
should sometimes in practice just to get a feel for it.”

Who Should Consider The Stack System?

And based on this complete list of pros and cons drawn from my own experience of extensively reviewing the Stack System here is whom I would say are ideal candidates to use it:

• Competitive golfers serious about significant distance gains and who are happy to spend $100s to achieve that.
• Disciplined trainers who can commit to consistent 2x weekly sessions
• Players with time to work on any negative accuracy impact at higher swing speeds
• Tech-savvy golfers comfortable with app-based training.

I would recommend switching your ‘Golfing Focus’ elsewhere though if you are:

• A casual golfer prioritizing fun and consistency over raw driving distance
• Time-constrained players when it comes to practice (like many juggling family and work commitments to schedule normal golf play and general practice time.)
• The Budget-conscious ($100s of upfront and also an ongoing cost with the yearly software subscription)
• Golfers already struggling with accuracy (system will likely make this worse initially)
• Android cell / mobile users (currently not supported)

The Bottom Line: My Honest Assessment

After 11 weeks with the Stack System, I must confess I remain genuinely conflicted.

The speed gains are real — I measurably increased my swing speed and got tantalizingly close to that 300-yard goal.

But the accuracy trade-off and the consistent training time required on top of everything else I need to practice, in and amongst normal family life, has me questioning whether it’s worth continuing.

And that’s before also I factor in the time to actually get out onto the course and play a round or even a few holes.

I suspect therefore I will focus my attention elsewhere when it comes to my golf for now.

But having spent the vast majority of the money now required to use the Stack System on a long term basis I do know I have a clear path back to more potential distance gains should I choose to return to it in the future.

The system works as advertised for speed gains. 

The question each golfer must answer is whether the time commitment, cost, and potential accuracy impact aligns with their golfing goals and available practice and playing time.

If you’re a competitive and/or serious golfer with time to practice the answer is clearly yes – the advantages of more distance in golf are undeniable.

But for time-poor recreational golfers like many of us? The equation becomes much more complex.

[Editor’s note – One option you could choose is to test it out for a couple of weeks to see what you think. The Stack System offers full refunds (minus shipping costs) within 30 days if you are not satisfied!]

What would you choose—the extra distance or maintaining your current accuracy?
