While we are on the topic of skinny people, I have some questions.

Im 6', 133 lbs. Im looking to be stronger, and gain muscle.

Ive been doing 70 pushups a night, 3 sets of curls 10 reps (28lbs), and 70 crunches.
Sound like a decent workout?

Ive been drinking Whey and I cant really tell if its working. Could Creatine benefit me more?

Any tips?

PS. After doing pushups for 3 months now, I have boobs, but my arms arent any bigger.
