You're tired! Take a couple of days off and then you'll be amazed at how fast you can go.
Well I'll concede that I feel tired. But isn't that part of building a base? That is, pushing to exhaustion to build endurance? However I'm definitely going to follow your advice before my 2k record attempt next month, and take a couple of days off.
Sorry to hear of your latest back spasm in the middle of the night. Are you sure your bed and mattress is giving you adequate support, and allowing those lower back muscles to fully relax and rest?
I think we are getting a new mattress soon. However, when I had the spasm I was napping on the massage table, which usually is more comfortable for me when my back is hurting.
Pushing to exhaustion is only part of it. Adequate recovery is just as important.
I guess I just can't adjust to getting older. I think you're right. I'm going to have to learn to do less; expect less. Somehow this last year, my 76th, has seemed to slow me down much more than past years.
It is an accelerating process, this aging. This has certainly been my most difficult year so far, although I have hope for improvement.
What you are facing with rowing is not necessarily age related. A person can grind along doing long workouts, getting some grudging improvement, but without adequate rest and recovery, you won't reach your maximum potential. Just try staying away from the rower completely for say, three days, and then see how it feels on the 4th day. I would bet you go quite a bit faster. You can look for the signs of growing fatigue, and take a day or two off to build your strength back up. I think you'll be surprised by how much faster you can improve.
But was the golk course closed??
