Hi Rhonda,
On tricep exercises, I think I'm the one who wrote (in my letter to the new gym member) that kickbacks are a waste of time. I vaguely recall a follow-up exchange laying out why. I won't replicate it again, but it has to do with the limited range of the motion in which you are actually putting tension on the muscles that you are trying to target. Plus the fact that most people tend to do them incorrectly: see
http://www.exrx.net/Kinesiology/Erro...l#anchor973147. Even if done correctly, though, kickbacks are simply an inefficient way to work tris. Yes, you can get a good "pump" with high rep kickbacks, but pump /= hypertrophy (growth).
However, and this is a big however, kickbacks aren't the same as extensions. See
http://www.exrx.net/Lists/ExList/ArmWt.html for a list of tri extension variations.
Another comment on the upper body routine: pulldowns are great for lats and upper back, but don't hit the mid-back all that effectively. You don't have any mid-back exercises in the list. Maybe add some low cable rows or bent-over barbell rows?
If you needed to excise an exercise to fit in rows, I'd eliminate one of the two isolation tri exercises -- facepulls work tris, as do the tri extensions. Or, shrugs. If you're also deadlifting, you're probably hitting your traps pretty hard anyway. And, maybe this is just me, but it's easy to get overdeveloped traps (relative to the other muscles in the back and shoulder). IMO, this not only looks funny, but makes my bra straps slip down all the time.
And, here we are, back to Tomato's suggestion of toplessness.
