Speed Training with The Stack System
I'm a big fan of speed training: if you don't use it, you lose it and I personally use The Stack System. To get started you need The Stack System Equipment and App is for IOS Devices only along with swing speed measurement. I use the Voice Caddie SC200 Plus.
This system is one with artificial intelligence, modeled after years of study by one of golf's leading PhD's (Dr. Sasho MacKenzie), and engineered by one of the smarter guys in club manufacturing/design (Marty Jertson,).
The Stack System is a 42" (hybrid length) shaft with a removable screw-on cap with a series of interchangeable weights. The program has an app (IOS Only) that will dynamically and intelligently change what it asks you to do — the weights and reps it asks of you each day you train — and the feedback is cycled back to the creators so that they can continue to refine their algorithms.
I can't say it much better than Dr MacKenzie himself, so:
