I went for a run for the first time in a while yesterday. For various reasons, I have been to the gym erratically since the beginning of the year, unfortunately. The run (four miles) was good, so I must be in better cardio shape than I thought, and I feel fine muscle-wise today.
I am again perpetually rethinking my exercise regimen. Someone who had not seen me since November had remarked the other day that I had lost weight, and since I have lost a lot of muscle mass that is true. Alas. Really, I simply need to exercise regularly again.
