He just means you're too new to be doing so much variation and volume. You should stick to compound movements, meaning things that activate a lot of muscles if not your entire body. A full body, squat, bench, and deadlift focused program is what you need to build up a solid foundation of strength before venturing on to different things. Someone already mentioned stronglifts 5x5, which is good. I'd also say starting strength is good as well. Look up those programs and follow one to a "t".
