Only times I have missed in 8 years.
My sons arrival in the world,(10/02) 2 weeks off. Felt great when I got started back.
Thanksgiving, Easter and Christmas day, although I did work out on Chrstmas day one year, 01 I believe....
I usually don't work on Wed and Sun, therefore I ALWAYS take Sunday off. I usually have a light day on Wednesdays.
I remember back in 03 when I was in training for a job, they sent me to SC for 1 month put me up in an APT, meal ticket, etc. I bought a 1 month membership to Powerhouse GYM in GREER, SC. I was in training with 30 other people, they all said "why did you pay for that for 1 month" I proceed to look at all of them, who ALL were 50-100 lbs overweight. I just laughed and said 'becasue I dont miss the gym, no matter what" I was up at 5AM the entire month while they all went and had hamburgers and beer til 1AM
