Purchasing & Packaging

How long will my GFS Trainer last?

We take great pride in providing our customers with quality products that are built to last! The base of your trainer will last seasons upon seasons. We offer replacement parts and kits under our 'Shop' drop-down if you are seeing ware and tear on your trainer. 

Do I have to purchase a new trainer for each of the trainer models?

Although we won't stop you, you absolutely do NOT need to purchase a full trainer for each version of our trainers. We offer Interchangeable kits under the 'Shop' drop-down to change your Trainer from one version to another. All kits include the proper tools needed to use the kits. 

I train with both baseball and softball players on pitching and hitting, do I need to purchase a King of the Hill, Queen of the Hill, and a King of the Swing separately?

No! You can purchase Interchangeable Kits for each version of our trainers to switch from King of the Hill to Queen of the Hill to King of the Swing under the 'Shop' drop-down.

I just received my package, what now?

Why are there two springs included in my package?

The blue spring that is installed in the trainer upon arrival is the beginner spring. The gold spring included is an advanced spring used once you have completely mastered each level of tension on the blue spring. We HIGHLY recommend taking the time to move through each level slowly and completely to ensure you have mastered and are using the proper mechanics and are not compromising the health of your arm/body.

Why is ground force so important in pitching/hitting?

Great question! We have in depth literature on our site that explains the necessity of ground force and how it will develop you into an elite level player. For pitching, read here. For fastpitch, read here. For hitting, read here. 

Do you have any science or studies to back up your theories?

We sure do! We have listed them on each 'The Science of...' pages under the individual product drop-down's. For pitching, read here. For fastpitch, read here. For hitting, read here.  

How long does it take to see improvement with the GFS Trainers?

Most of our customers see immediate improvement once players are able to feel their bodies in action on the Trainer. In our experience, we can confidently say you will likely see an increase in velocity/bat speed in as little as one week when using the GFS Trainers in a regular training program. 

How much does the trainer weigh? Can I take it with me on the go?

The trainer is built to last at 21 pounds! You can take the trainer with you on the go on nearly any surface, or bolt it to a mound or the ground in a facility. 

Where can I use the trainer?

The trainer has a piece of foam attached to the underside of the base to allow you to use the trainer indoors or outdoors on any flat surface. If you notice your trainer's grip starting to wear after regular use, you can purchase replacement foam to re-adhere. 

At what age can I start using the trainer for my player(s)?

The GFS Trainers are intended for use at any age. One great feature of the Trainers is that it aids in proper mechanics, so we put our entry-level players on the Trainers to teach the feel of proper mechanics.

Do you have drills so I can learn to use my trainer? 

We do! Check out our training pages under each version of trainer. For pitching, click here. For fastpitch, click here. For hitting, click here.
