He's just like a doctor -- sees tons of different people all the time, it's a job to him -- I doubt he will walk away saying "what a bunch of crazy questions" -- remember, all the "hot" people at the gym probably spent their first week asking him questions to. And, why pay the membership fee and miss out on using the equipment you want. If you try to figure it out on your own, you risk looking lost anyway and wasting time you could use for a good workout. Besides, now that you are lifting weights, you get to hang out with the "beautiful people" too -- which makes you one of them!! Make yourself a role model for the next person who is too shy to ask for help!! Good luck.
