Pure ShadeZ

Hello! I just recently go back into play Runescape 3 after a long and hard break of not playing for almost a few years now. A lot of friends seemed to get back into after the Evolution of Combat update came into play and enjoy it, and of course they talked me back into making an account and joining them on their adventurers. So from that I created a new account just today and everyone told me to go Range Pure, I've never had a pure before so I decided to accept the challenge and go on with it. I just began the first quest/tutorial stage and it seems that you're automatically given a bronze sword. And from that I hit a giant brick wall. Be main goal is to strictly keep my Strength, Defense, and Attack at level 1 and boosting my Constitution and Ranging levels to the max. I can't seem to access my backpack/inventory during the beginning stage and this leads my to gaining my Defense level to level 2. I hate to have it had level 2, yes, a bit OCD with numbers. Is there anyway that you could not gain any Str, Def, or Att XP during the starting stage?
