Now where are my gains? I still have a weak and slow stroke. I typically do my steady state work at 20-22spm at 2:20 pace. I will admit to being in the best shape of my life at 55 years old. Very lean with minimal body fat, but I've lost so much weight from all of this rowing that I am now down to my lowest weight in 40 years (154lbs). My endurance for other sports (skiing, biking and tennis) has improved significantly.
However, I still have poor power on the erg. Take a look at my power curve. Long, low, smooth curve. This is my typical steady state pattern.

Any thoughts or suggestions?
Sorry for the rant, but it sucks being so weak!
