I just completed my second week, and I feel really good.
I have never been a regular at the gym, I have worked out a little from time to time, but never followed a program or had any long time commitments.
My work is both day and evening shifts, and since I also work some weekends with 2X12 hour shifts I even have some weekdays off from work. I have a gym membership at the local public swimming pool, so in addition to normal weights, treadmills and other normal gym equipment I also have access to a 25m swimming pool, sauna and steam room. The sauna is what I normally use as a "reward" after a gym session.
The "month 1" program works really well with my weekly schedule. Most Mondays I have about an hour by myself in the morning from the kids and my fiancee leave for kindergarten/school/work and until need to go to work myself and that is just about enough time for 3 sets of warmup and three sets of the upper body workout routine, a little cool down and a shower. Most Wednesdays I work the late shift and have more than enough time for leg day. At the moment I'm doing strength workouts at home and do the cardio days at the gym. I would go outside running for cardio, but it's winter here and really terrible weather conditions.
