Many lifters never had someone to teach them the power clean (myself included), but still do it fairly successfully. It isn't that hard and it wouldn't have been included in the book if it was impossible to teach it to yourself. Infact, the technical difficulty of the lift is part of the reason it is so useful: the coordination/balance/timing you develop from doing it is actually quite applicable to using your strength/power in real life. Also, if we are going to mention the SS book, you may want to pay attention to what Rippetoe actually says about substituting the row for the the power clean (pg 289):
"If you are avoiding the clean because you don't want to have to learn how to do it, it is suggested that this might not be the best way to approach your training."
Obviously, it's not going to kill you, but as a beginner in your first weeks of SS, it isn't a great idea to get in the habit of tweaking the programming whenever you feel like it. The programming is setup the way it is because this scheme has proven to work best for the majority of people - any changes to it will most likely be less effective. An occasional 1RM is no big deal, but twice in your first 3 weeks seems excessive.
At any rate, good luck with the program!
I'm definitely with you on the PC thing, and I'm trying to learn it...but for now I use my rows as my heavy worksets. I'm having a lot of trouble doing everything smooth...it's jerky and my hip "thrst" after the initial pull is very awkward....I don't feel like I'm getting power from it.
And for the deads....the first 1RM was after my 5 rep sets. The second was after a warmup of 275(ish??)x4....which is still higher than my last workset.
That's the only change I have made to the program, I'm sticking to the T for the rest of it really. One day of extra deads did nothing but boost my confidence and give me more inspiration. Not what Mark says to do, but it felt good and made me feel strong. The 365 after 3 weeks was pretty awesome for me. I don't like tweaking the program, as the idea gets shot down often, but sometimes i don't feel tired yet after my dead lifts, so I do more. Eh, oh well.
The only other thing I do is sub in some dips or maybe some pullups, and I love to do lateral raises with dumbbells because my shoulders need a lot of work, and they aren't interfering with my progress, so I should be alright. I'm keeping an eye on everything for now.
Thanks man. Eventually I'll learn how to clean. =/
