First I would like to thank you for providing some of your videos on lifting technique hosted at crossfit.com. Your deadlift starting position video was enlightening to say the least.

I got into lifting around age 18 weighing a skinny 150lbs. Over the next few years I gained 40-50lbs of decent weight through lifting and eating somewhat well.

I got married a few years ago and magically sled into physical decline. Recently, however, I have started crossfitting and trying to get my strength back up. Today I am 31 years old, 215 lbs, ~20% bodyfat based on the weight/height/wrist/waist method.

I regularly do calisthenics but have not lifted seriously in years. Here are my current abilities on some lifts:

deadlift - worked up to a triple with 305lbs. I have never trained the DL seriously.

bench - set of 10 reps with 200lbs. Normally when I bench with any regularity I shoot up to 3x8-10 with 225lbs.

squat - have not tried any "heavy" weights in the squat recently nor have I ever. The squat is by far my weakest lift in terms of ability and understanding of technique.

power clean - triple with 185lbs. I just learned these this week.

My question is - would a Starting Strength routine serve me well in helping to get my poundages up? I ask because I imagine I am older than the routine's target demographic and am not exactly a beginner but far from intermediate level, especially on the squat.

Also, since I am already relatively heavy for my height, would I expect to gain weight on the SS program but just less and slower than a skinny teen?
