It looked like a long tough spring with two handles on each side. This one time I went to a compactor room in my appt building and saw that someone threw out a peculiar item. I am glad someone started this thread, because I have a chance to chime in on my power twister that is designed to work in a very similar way to the ISO 7x. This device is sort of like a bullworker or a power twister. Triceps and Biceps is where i'm feeling the largest difference at the moment. Upper back+ shoulders (Like pulling a bow) Right now, i'm doing the following things they list on their chart om top of 50 push ups+50 sit ups:Ĭhest (Doesn't seem more effective than push ups)

You think it might be worth to take either protein shakes or bar to compliment the exercise? True what you said though, soreness is not the most accurate indicator. I'm trying to push myself a bit considering i had a 4 month run in with a gym a while back(6 months ago?), so it's not like i'm starting from complete zero. This one has increased resistance up to 165LBs. Mostly just a redesigned version of the bullworker from back in the 80s. I knew it wasn't anything amazingly revolutionary. It does have advantages for working certain muscles(Biceps for example, when you can't afford to purchase and maintain a full set of dumbbells) or working your back a little bit along with chest and shoulders. The $10 i paid for is worth the extra convenience i would say. Click to expand.Yea, I was reading at the store while sitting a shoes measuring bench.
