Looking at the pictures of Sigs gym the barbells are the same as the one sold on Ebay. I just did not remember the knobs on each end. I recently found a picture of myself using two 80 lb. dumbells on the incline board. The board was attached in the barbell rack shown in the pictures above. These dumbells I believe are the same ones seen in many pictures on the net that Sig is lifting. I have read that they weighed 75 lbs. but Sig said they were 80 lbs. Sig had 75 lbs. dumbells already in the dumbell rack. So 80 lbs make sense. The next pair of dumbells were 100 lbs, abit to heavy for me on the incline board, but not on the flat bench.
