Hello Jenn, I had my L4 and L5 vertebrae's fused about 6 years ago. I used to have a very active job, and now I have been setting behind a desk for about 5 years. I am wanting to start training for for playing pool tournaments. I have noticed lately that I am starting to get very tired in my legs after about an hour and a half of practice time. With your background I was wondering if you could give me some advise on how to get started with a training program. Also congratulation on a great 2004 and I am looking forward to seeing you have a better 2005 year.
