I’ve decided to end my experiment with the 100Up exercise. Today would have marked the end of the fourth week of doing it on a daily basis, except that I stopped doing it four days ago.
For the first three and a half weeks, I think it was doing some good. I saw (or was willing to believe that I saw) some improvements in leg strength, form, and ease of motion when running. However, as I moved from doing all minor sets (walking in place) to including more major sets (running in place), my left hip began to hurt. That’s the hip I broke six years ago. I had hoped the 100Ups would strengthen the chronically weak soft tissue there, but, in the end, it was doing more harm than good.
I still think the 100Up exercise is a good one. It just doesn’t work for me. I can run long distances, and am running more quickly than I used to, without any trouble at all. But lifting my knees as high as is needed in the 100Up exercise seems to place an undue amount of stress on my hip, and the results aren’t good. It may be that I can strengthen the hip by doing deep squats, and so might try that. Or it may be that I’ll simply leave well enough alone, and continue what I’ve been doing so far.
As I’ve said before, the “experiment of one” continues…
