Gym Advice needed!

OK, I need help with my work out regime. We usually go to the gym 3 times a week but are trying to increase it to at least 5. I want to lose 5 or 6 lbs and tone by October, especially my arms/back! I have been eating pretty healthy, and drinking tons of water.
I usually spend 30-35 min on the elliptical, then 4 sets of 12 on the rowing machine (for back/arms, at 30 lbs) Then I do the glute machine (don't know what it is called, but you lie on your stomach and push back the lever with one leg, then switch, 3 sets of 10. What else should I be doing or should I change anything?

Tricep dips off a bench
Push ups
Lat pull downs (I do 90 pounds) the more weight the more calories you burn - you wont bulk up ... Use free weights (I use 12 pounds for shoulders, 15 pounds for biceps)

HTH! Good luck

I would add intervals to your elliptical sessions - short burts of maximum exertion, followed by periods at lower intenstiy.

If you google you can find different suggestions on what will work for you.

If you do the same thing every time you work out your body will adjust to that routine - so the intervals will mix it up a bit.
