I noticed last week that Busy Body had the new Hoist V-Core home gym on their showroom, so I had to show you all what this machine is all about...- THE CORE!  The big revolution in this home gym is that it has a very unstable seat/foot arrangement that can be used with or without a back support to create a spectrum of instability from a bit unstable to very unstable.  I go through the entire spectrum in this video to show you exactly how this machine works to strengthen your core.  The machine also has a cable system that has adjustable arms and adds some good variation for your workouts. 

Have you tried the Hoise V-Core?  What are you using for your home workout?
