Hello! I'm in need of a little advice re: my strength training routine. (i'm female)

In the past year I've lost about 70 pounds, but almost 50 of its since October 2006. I eat between 1450-1750 calories/ day which puts me at about a 2lb loss per week. Thankfully I have yet to plateau, and all seems well diet wise.

My question deals with my workout routine. I do cardio each time I go to the gym (anywhere from 30-45 mins of running/walking, intervals, treadmill incline, etc 4-5x/week). I sweat like a pig. I vary lifting my arms and legs-one or hte other each time I go.

When it comes to strength training I use almost exclusively free weights, lunges, squats, pushups, medicine ball toss ,etc. But its gotten to the point that I'm getting strong-weirdly strong. I feel a bit like the amazon woman at the gym. Yesterday I was doing my lunges with free weight bicep curls and the trainer asked me how long I'd been training to get to this point. That isn't flattering-it concerns me.

Should I actually continue to UP the weight I'm using as I improve? I know that I cannot really BULK up-i'm in a calorie deficit and lacking the testosterone for it- but lifting really heavy weights makes me nervous. And i REALLY don't want to gain a frickin pound. Should I spend less time on the weights?

Thank you for your help!!

If you feel your muscles are getting to big and you don't like the way they look then focus a little less on weights or keep doing the same weight.

I just recently increased the weights I am doing and decreased the reps. I'm doing 3 sets of 4-6 reps with higher weights and am also in a caloric deficit. (Per one of the more knowledgeable people on the board) I haven't really seen much as far as changes (bulking), but I am seeing weight loss.

Curious, how much weight are you moving with your strength training? What is your routine?
