Hammer strength jammer

i just youtubed it beause i had no idea what the jammer was

looks good for sports and power purposes. i guess it depends on the goal
 
Never bad to have an extra option in the routine
 
The jammer is great for explosive strength. It is also pretty easy on the joints for being an explosive movement. Used the hell out of it when I was in high school. Does your gym have one?? I haven't seen one outside of a high school or college gym!

I work at a used sports store so I set up my whole basement with equipment I come across in the store and I'm considering getting a jammer
