Don't worry about it! I did the same thing when I started less than 2 weeks ago. I think the program is popular enough that most people in the weight room can guess what you are doing. Even if they are not familiar with the program they will just assume you are working on proper form.

For me, starting this way really helped me feel better about my form being correct and with 5 pounds being added each workout it won't be this way forever.

I'm 6'4 330lbs. If you think the empty bar is bad, wait unit you look at it with those itty bitty 2.5 lb plates on either end! It's not about what it looks like, it's what you end up with. Stick to the guide. It'll get hard soon enough.

If you read Rippetoe's stuff, he says if you have experience lifting or it’s just ridiculously easy, you can increase by 10 lbs instead of 5 for the first few weeks or so.

@RmeDude I hear ya on feeling kind of silly. I just finished week one and feel like the biggest challenge was finding the 2.5LB plates at the gym. But I do like the idea of it being a process, reminds me of when I started running; walk first then run.
