After 8 sets of various exercises & two previous sets in this machine, I could only do 10 reps....& then I had a memorable experience. This is how it is...every time I work out. I call it the "Neck Bone Machine" because that's where I feel the most tension every time I curl my legs. I think the machine is supposed to develop strong neck bone muscles. I feel maximum stress right on my brain stem in the back of the neck. But, it's always a nonstop party at the gym. You'll see me naked soon....as soon as I get in shape. Probably in 2016. That's when I'll share my before and after pics.
