The Power Bag is a tool no hitter should train without. Lance Berkman (pictured) credits a similar device his father made with much of the power he has in his wrist and forearms. This power and strength at contact result in more spring off of the bat head. Bat speed is crucial for hitting the ball a long way, but if there is give in the wrist at contact much of the benefit of bat speed is lost. Strengthening the hands, wrist and forearms by using the Power Bag will decrease the amount of recoil and cause the ball to JUMP off of your bat.



The Power Bag was specifically designed to allow the hitter to swing through the bag. The bag has a 1/2 steel cable that runs down the center. This gives the bag flexibility and allows the hitter to begin moving the bag at contact. Hitting a sturdy tire or similar device can cause a hitter to develop the bad habit of not finishing the swing. A ball is in contact with a bat only 1/2000 of a second and some will have you believe any energy spent after contact is wasted. In theory this may be correct, but how many times as a coach or parent have you noticed players of all ages give up on a swing? By teaching players to always finish their swing when using a heavy bag you help them develop good habits that eventually translate into harder hit balls and sound muscle memory mechanics.

The power bag comes with everything you need to mount to a pole 3 ½” diameter or smaller. You get the top arm and u-bolts to mount to a pole. The bag can be removed from the arm after use for safe storage.

Our bags consist of polyurethane molded around a light foam. Polyurethane is the same material used in pitching machine balls. It is tear resistant and absorbs impact extremely well. We use a lower durometer material to make the bag flexible enough to absorb bat impact and cushion the blow when being hit with a bat. It also comes with a two year limited warranty.

We feel it is best to follow these guild lines. If you are unsure, please call us. 888-766-8772. We have received input from many coaches over years and can help you make the best decision possible based on what your needs are. The guidelines below are what we recommend.

Large Power Bag 7.5 lbs – Average size boys 15 and over, High school baseball, college baseball and pros. A college player should be able to hit this bag all the way around. We have had a few HS baseball coaches say they prefer the medium bag since it is easier to hit through. We feel this bag is best for most HS programs. The more you use it, the stronger the kids get and the easier it becomes as the season goes along.

Medium Power Bag 5.5 lbs – Smaller boys 14 and over, All high school and college girls. We have had several HS fastpitch coaches inform us that by the end of their first year using this bag, 4-6 of their girls were hitting this bag all the way around. Zero were at the beginning of the year.

Junior Power Bag 3.5 lbs– Most all players 13 and under. This bag is somewhat closer to hitting a deflated basketball though heavier. As a coach it depends on what you are after. This bag does not hang as far from the top arm as the other two making it easier to hit around. Most 9 year old boys will get it around once with practice, 12 year old boys 2-4 times, average 14 year old 5-8 times. This bag is perfect for teaching the younger kids why good mechanics lead to more power.
