Once in a while when I'm training for Iron Man, I'll start fitting in three workouts a day on certain days. But I usually make up for it and only do one on the following day. Lots of people enjoy sports, especially when they're in school. I've gradually discovered that I'm definitely suited for endurance sports. The more distance that I do, the better.
Some people have the knack for that.
I've had to take off time for my child and injuries and various things. I know that I have to work at it to be good. I'm not a natural at anything. I'm slow when I first start back. So I guess I am a mere mortal that just works hard at it.
