Swing the System! – Baseball

Baseball players at the highest competitive levels – players like Evan Longoria, Tampa Bay Rays third baseman, and Dustin Pedroia, Boston Red Sox second baseman – are now relying on the Hitting Jack-It^TM System, the leading variable weighted hitting system, for building Strength & Power and improving their hitting skills.

The Hitting Jack-It^TM System is a cone-shaped, rubber-coated carbon steel weight with an open side that slips onto the handle of the bat and fits snugly at the bottom of the bat barrel above the batter’s hands.

The Hitting Jack-It^TM System was developed as a complete hitting system “by ball players for ball players” to provide immediate results, quickly build bat speed and power, and force the batter’s hands to work properly, thus creating improved technique.

The first and only weighted system on the market that can be used to hit “live” (with a pitcher) batting practice, the Hitting Jack-It^TM System comes in four sizes to assist progressive training.

9 oz. – Ages 8 and up – Increase Bat Speed
12 oz. – Ages 12 and up – Increase Strength
16 oz. – Ages 15 and up – Increase Power
21 oz. – Ages 15 and up – “On-deck” size builds Big League Power

The Hitting Jack-It^TM System works with all baseball and softball bats, which enables players to develop their strength and power during live batting practice sessions and when hitting off tees.
