so I started gong to the gym. First it was twice a week, doing 15 minutes on the eliptical and a full-body circuit on the weights. After a few weeks I switched to a 2-day split, pulling exercises and pushing exercises. Then I added a day for legs. I was feeling stronger, my body mass was shifting from fat to muscle, and I was adding weight and resistance to my exercises.
Then one day I found myself having to run three blocks to catch a bus. In combat boots. Pulling a small suitcase.
When I got to the bus there was a great cheer from all the passengers (no there wasn't, but I like to think there was). But I was out of breath, like I had been fighting in armor for a minute or so. In the course of the run my legs got tired lifting up those heavy boots. I realized what it was: I am still out of shape.
I went into the gym his week and decided to do functional movements; the warm-up exercises that we would do in Brazilian jiu jitsu class, for instance. They kicked my ass. These were things that wee never "easy," but in time, I was able to do. Now it's a drag to do more than one or two reps.
All those months of "healing" did my conditioning no favors. We got a lot of work to do.
The good news is that I discovered that yes, I can run again. The knee is no longer the problem. Now I an run every day if I want to. And I think I shall.
Look out world!
