Regular batting donuts focus all the bat weight on the barrel, which can lead to casting and poor swing mechanics. The Hitting Jack-It solves this problem - its design keeps hands from casting while building power, bat speed, and proper form. 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 Super Slugger for building strength & power and improving their hitting skills. Features 9 oz, 12oz, and 16oz weights all available individually Works with all baseball and softball bats Great for baseball and softball players of all levels (age 8 and up) Provides instant feedback Helps build power and bat speed Far superior to regular batting donuts that can cause casting Forces hands to work properly, creating a shorter compact swing Strengthens hands and forearms Use with live hitting, tee work, or as an on-deck weight
