Broccoli? And Shoulder/Back Stability

Firstly, whats the best way to prepare broccoli, as far as keeping in nutrients?

Also I used to be able to do a stradle-planche, but because of my recent weight gains I am unable to hold the position withoutmy shoulders collapsing from their foward position. Is there any extra excercise I could add onto my program to keep up my strength as far as keeping my shoulder from collapsing back (stopping the shoulder blades coming together in my upper back)?

i just eat my broc. raw. Crunch it.
