Hey guys whats up. So I weigh about 125, and I'm going to quit bein a lazy stoner and start getting into a good hobby. My goal is to reach 150 and I am going to do WBB1. I have 2 questions

1. What should I eat thats going to help me gain weight?

2. The reps and the sets are pretty low on WBB1...am I just supposed to do the heaviest weight I can do or something?

Thanks for any help guys.
