Wow! So much information! Thanks everyone.
HRBabe, thanks for the book recommendation. I’ll look into it—I can definitely use all the help I can get!
Ok, Depalma, you’ve convinced me to do not to the splits and to focus instead on large muscle groups. I like it!
I’m trying to understand the principles at work here, so please bear with me. I’ve translated your suggested upper body workout into terms that make sense to me, and it looks like this:
Upper Body, Variant One
Bench Press (push; chest)
(Assisted) Pull Ups (pull; back)
DB Military Press (push; shoulders)
Bent Over Row (pull; back)
Upper Body, Variant Two
DB Decline Bench Press (push; chest)
Lat Pulldowns (pull; shoulders)
Incline Bench Press/DB press (push; chest)
One Arm DB Row (pull, back)
Now my questions:
Am I to conclude that you’ve given me the variant so that one day I slightly emphasize my back and the other day I slightly emphasize my chest? Is that the principle at work or is it just the need for variety?
I notice that all the chest exercises are pushes and all the back exercises are pulls; shoulders are the only ones that have push and pull exercises. Can you tell me why that is? I thought you were supposed to do a push and a pull on each muscle group; is it rather than you’re just supposed to do general pushing and pulling regardless of the muscle group?
Are you sure that these chest/back/shoulders exercises are going to be enough for tightening up my arms? Beyond building muscle mass for calorie-burning purposes, and giving myself goals that will keep me going to the gym now that I’m maintaining, one of my primary reasons for weight training is to have nice arms for tank tops this summer. (Lame, I know, but there it is!)
Finally, I work out alone—no spotter. Can I really do bb bench presses (flat and incline) by myself without hurting myself by dropping a bar on my head? Is there any reason not to use dumbbells instead for all those exercises?
(I’m going to skip the supersets for the time being—there are A LOT of new exercises here for me—the only ones I’ve ever done are the assisted pull ups and the lat pulldowns—and I’d rather get comfortable with the general form and weight levels before I start messing around with supersets. Sound cool?)
I think the “2 for 2” method of progression might make more sense for me than the decreasing weight/increasing reps method, just because I don’t want to be messing around changing the weights all the time. I’m going to give it a shot and see how I go.
Thanks again for all the help and suggestions! It’s great.
I did my first day of the lower body workout today and my legs feel stiff, sore and wobbly despite stretching out before and after—so it probably worked.

I wound up doing (unweighted) stationary lunges rather than regular lunges because my knee began to twinge after the first set and one of the trainers showed me the alternative. I used super-light weights on the deadlift and complained later to the helpful trainer that I didn’t feel I had really gotten a proper workout—he put me up on a stepper and handed me a 25lb barbell; I think both of those things will help when I do lower body again later in the week. So, hooray! (I have to say, I love that there’s a trainer at my gym who always comes to help me when he sees me messing something up—poor form or not enough weight or whatever. I would probably feel much more wary about trying so many new exercises if I didn’t know that the-guy-who-always-helps-me was going to help me. One of these days I’ll have to start paying him

Cheers!
