Useful
I have used Bullworker, or like exercisers, for twenty years.  My Dad's best friend carried a Bullworker with him around the Middle East working for Bechtel.  The Iso 7x is obviously another brand of the Bullworker.  I have had several Iso 7x.  I usually have one in my classroom.  Usually a student wants one.  At the end of the year I give him/her mine and buy another.  Personally I prefer the nylon strap over the cable.  I have had one break, fortunately at the time my reflexes were still good, I avoided any injury.  I think the key to these type of exercisers is using the isometric option.  Isometrics are effective and using this isometrically is your best option in my opionion.  A seven second push or pulled hold is good.  If you are having wrist pain, or other physical issues, back off on your compression.  I believe building strength with the Iso 7x helps build strength for skiing.  Enjoy yours!
