I am relatively new to lifting weights, only been lifting for 3 months and have put on 4.4 pounds of muscle (yay me) and I have some Dumb Questions:
1) My gym programme includes 1 lower body weight exercises and 3 upper body ones. I do it three times a week. Can I then add 1-2 further sessions a week at home lifting dumb-bells on different days or would that be too much of a strain on my upper body muscles? Should I isolate the muscle groups and work them on different days? Note - I never get any residual pain in my arms or upper body when I do work them hard - they can take it!

2) Is it true that you shouldn't lift before doing your cardio at the gym? I read somewhere that it renders your weight workout useless. That sounded spurious to me, but I am concerned enough to check it out ...
3) Strange as it may seem, I WANT lovely plump muscles! Most women are afraid of bulk, but it doesn't scare me - I like the nice curvy muscly look. Any tips?
4) What's this whole working to failure thing? Does that mean working heavy enough weights that you can barely do the last rep?! If so, I've got THAT down pat LOL!
Thanks gals!!
Tam
