Also, others have mentioned getting a trainer. That's probably a good investment. I didn't but it was because my lifting buddy's wife is a trainer for athletic teams and helped me with my form the first month and she still works out with us from time to time. Her input was invaluable in helping me maintain my training. I had a bad back for a very long time and lifting has helped tremendously but only because she was able to instill proper form in me early!
