Why oh why do I torture myself?

Since the beginning of the new year, I have been painfully torturing myself at the gym. I can start to see the results, which is satisfying, but damn the pain! I always thought of myself as a strong person, some what athletic...but I guess that was 10 years ago, when I was actually playing soccer. Nope, I am a lazy sack of shit, that would rather sit my ass on the couch watching a hockey game. I manage to get up and go work out either before or after work, roughly 3-4 times a week. I have also managed to reject the mouth watering cheese cake that my mom keeps making. Unfortunately, my knitting has some what suffered. I am tired all the time and again...I would rather sit my ass on the couch watching a hockey game! With that said, I have started on a jacket! So far I only have about 75% of the back completed, and hope to finish it and start on the front panel this weekend.
