Broken Jam Balls
While the jam balls have been very effective in our speed and strength program, 3 out of the 4 25lb balls broke 14 months after they were purchased. The manufacturer has only a year warranty. With them being $45 a piece, they don't seem to be worth the money if they need to be replaced every year.

Great Workout Tool
I have incorporated this ball into my personal workouts as well as with my clients and it has proved to be a useful tool.

SLAM

Best all around workout!!
"I've found slammer ball workouts to be exhausting, And just about the most effective core-strengthening exercise I've done. Similar to kettle bells, but Unlike kettle bells there's less momentum to help You. I'm a very fit 220lbs guy, after a few minutes with A 30lbs ball, I'm winded!"
