The StrongerGrip Grip Balls were one of the first products available.  They continue to be popular and with good reason.  These gems are so versatile and functional.  The uses are only limited by your imagination. Here are a few ways to use them.

*Hook them to any gym pully machines.  Pull downs, low pulley rows, cable crossover machine where you can do an amazing amount of work with them, different angles, exercises and not only will your grip get worked, your core will kick in as well when trying the different exercises while holding on to them!

*Hook them up to a pull up bar and see what a challenge these provide!

*Hook them up to pulling sled.  So much to do with the sled.  Curl and pull,press and push, pull and row. My favorite, hook them to the sled with a exercise band.  This adds a real deal twist and gives your grip a relax/tension workout like in any sport where your grip is essential. 

*Hook them up to loading pins and do simple deadlifts or farmers walks.

You get the idea.  Simple, yet incredibly effective.  Add them to your training now!
