You are right about ignoring the scale. As long as jeans are loose, I don't worry much any more. When jeans get tight, it means I have slacked off and have to get serious again. An old country boy likes to eat. :^)
Although it has been maligned, is old and stodgy, the Mediterranean Food Pyramid has worked for me for many years. Although not the best diet, it is easy to follow, and does not impair one's ability to eat "regular" food when that is what is available. Many places where we eat when biking don't cater to a healthy life style. I have eaten so many bananas over the years I simply do not like them any more. I will gratefully accept them on a long ride, but would rather have most anything else.
At 160 lbs, and having biked pretty hard for 20 years, the upper body gets tired with the weights way before the legs when I do squats. I mainly use the weights to balance so I don't get knees in front of feet. Not a good thing at my age. A life time paying dues at the gym is paying off big time now.
When younger, I trained Sport Shooters, and worked with many National Champions. I still train Armed Professionals and Citizens in Armed and Open Hand Defensive Techniques, and think a good trainer should be able to demonstrate techniques they teach. Staying in shape is a tremendous edge at any age. I can still handle most folks half my age. This pays the bills, but cycling is the passion.
I loaded up on Powerbars at Krogers tonight. They were on sale for fifty cents. I guess I will go back for more tomorrow, sure am ready to ride.
Ride well, and often, my friends.
