This ball can withstand a few heavy workouts. It gets slippery though, so that's something to watch out for, which is why I say the quality is good (as compared to Muscle Driver). However, the price for this product can't be beat and this is an excellent addition to have in a home gym.
So far so good with this 'No Bounce' Slam Ball. Great for indoors as well as out. I have the 20# & it is challenging when used in a Tabata type workout. Another great fitness tool to use in the arsenal! If you're looking for a training tool w/ multi use: slams, abs.... This is it w/ great quality & price.
