After sitting down and figuring out my schedule vs. the OPT program, I decided to go with something similar to what you suggested, Dianas.
The original OPT is written so that you alternate A1 and A2 4x/week for 3 weeks, then rest for a week. You do the same thing with B1 and B2 (4x/week for 3 weeks, then a rest week). C1 and C2 are only to be done 2-3 times a week for 3 weeks, and that's the end of the program. -- A total of 33 lifting workouts for the program.
I'm going to work out 3x/week (Mon/Wed/Fri), still alternating A1, A2, A1, A2, etc. However, I'm going to tack on a 4th week onto the A and B workout periods before the rest weeks. That way, I'm still getting the same total of 33 lifting workouts in the program. It's extending the program by 2 extra weeks, but I think that will ultimately work better for my lifestyle.
I've always lacked consistency when it comes to workout programs. I knew that 4x/week involving Saturdays wouldn't work, and I'm sure after several weeks, lifting 4 times in 5 days would begin to wear on me.
I'm sure that altering the program in this way isn't the OPTimal way to do it, but for me I think it is the way that will keep me the most sane and consistent. I can work with my life schedule AND still get all my workouts done. My goal is to FINISH A PROGRAM for the first time ever. It should put me VERY close to my ultimate goal weight, too.
Thanks again for tossing out ideas/opinions for me--I appreciate it!
