Speed Core has helped me lengthen my yards.

I've been using Speed Core 5-10 minutes every other day. Before using Speed Core I was at 105.5 mph and now I'm at 116-117 mph.

When I first started using Speed Core, the first thing i noticed was my accuracy had improved. After a few months of using the Speed Core, I started hitting the driver about 15 yards further.

I really like the Speed Core Training device.

I've worked my way through the resistance bands and have found an increase in my swing speed and an increase in my flexibility. What I have been doing lately is with the resistance band on the lead side going is to go into my backswing pausing for a brief moment and then trying to fire my hips through the swing motion as fast as possible using the resistance band to help accelerate my hip motion. Lot's of fun.

I can play 36 holes and not get tired.

After starting Speed Core, I'm able to hit the ball over 300 yards again like when I was younger and I'm hitting it that far without working hard to do it. It just seems easy to hit it that far now.

After using Speed Core, I went up 8mph. I'm noticing at least 10-15 yards probably. Not only did it help me with distance but increased hip flexibility helped me with accuracy.

Portable and effective way to build strength in the right places.

After three weeks use and trying to turn more in my swing I have added several yards to my drive. I went from an average of 184 yards to 218 yards.
