I agree with the generalizations and will add my own:

Sometimes, the gym sounds like a maternity ward with the grunting and yelling. Come on, if we want to see how much weight you're lifting, we'll watch you!!!

I spend about 30-45 minutes / 5 days/week lifting. Then I'll do about 30 minutes of cardio (step mills are great!) with a good book. Right now, the weather is awful outside, so this is how I get my endorphin fix.

Regarding boredom, if I can get into a very concentrated, meditative state and really pay attention to form - muscles worked, both eccentric and concentric moves - it's almost as good as a yoga class. There is a great website for women who lift:
http://www.stumptuous.com/weights.html. I like the phrase she has: "You're going to hell unless you worship the Goddess of form!".

I do a split routine, right now it is push/pull. I'll be changing again soon. I always build my session around a major lift (squats, bench press or pull ups) and do assistive type lifts (squat day would be calf raises, leg extensions and hamstring curls, for example) around it.

I'll probably be going to a three day split: legs, chest/back, arms/shoulders.

I'm 48 years young, so I'm not into body building, per se. I want to keep strong on the bike (tricep exercises are helpful for keeping a good aerodynamic tuck on the road bike, for example).
