The past several years I've been adamant about getting to the Y two or three times a week to play racquetball. It's been great exercise, and for someone with a "sedentary" kind of job, and who is past 50, it has been great. I always felt better, was in relatively good shape and kept the pounds off.
Then in January our family turned it's attention to more pressing matters, and because I couldn't commit to regular times at the Y, I canceled my membership and stopped playing. Actually I stopped exercising altogether.
This morning I renewed my membership. Soon I'll be back on the court and for a while suffering due to using dormant muscles. But I look forward to feeling better and my pants not fitting so tight.
