Well, the subject about says it all. I purchased the adhesive backed seat pad when I bought the Model C and soon discovered how ineffective it was for me. So, then I bought a "rower" gel seat that was touted as being the seat pad to end all seat pads. A bit of an exaggeration I'm thinking since I still have the issue of tush sensitivity about 15 minutes into the row. At the 20 minute mark, in addition to the tush discomfort, I can feel numbness creeping down my left leg. At the 30 minute mark, I'm thinking I should quit. At the 45 minute mark, the leg isn't dead but the tush is definitely sore and I have to sit on the rower for a moment until good circulation is restored to the left leg. Hmmm, me thinks this is not the exercise scenario I envisioned. Oh, this has been evolving for a few years now and other than the fact I've slowed down a little for the last 66 years, no other machine related exercise has the same effect. I've also tried the towell trick for padding and quite honestly, all shifting cloth does is contribute to the problem. Any further suggestions would be appreciated. Thanks.
