I think the "coaches" here will tell you to just follow the program as written.
It's designed for untrained novices and, if you start at low weights for each of the lifts and allow for a modest linear progression in the weights added, you'll have sufficient time to gain strength and improve your lifting technique until the weights become challenging. You'll ultimately reach your stall weights at some point during the program, which will require to you to deload and reset the weights used to get past your particular lifting plateaus.
If you haven't found it yet, check out the Starting Strength Wiki website at: http://startingstrength.wikia.com/wi..._Strength_Wiki. There's a lot of additional info posted there that's not made clear in the book or this forum. A good place to start is the Starting Strength Wiki FAQs page at: http://startingstrength.wikia.com/wiki/FAQ:The_Program. You can also find a link to the Logbook Calculator in the FAQs which is useful to planning out your individual lifting "program."
You can also ask for help in the one of the "Programming" forums (there are 2 of them -- one for Starting Strength and one for Strength & Conditioning) but, if that doesn't work, you'll probably need to buy Rip's other book "Practical Programming" to get more information: http://aasgaardco.com/store/store.ph...on=show_detail
Good luck!
