I went to a PT for a while a few years ago, and when I started working out myself I kinda wanted a workout partner. Then I realized how hard it was to find someone who wanted to lift on my schedule, then I realized some other things I am finnicky about with my weight lifting. I'm very strict on my rest periods, I don't like to talk between sets, I like being able to concentrate very hard on exactly what I am doing, and most importantly I feel that lifting alone forces me to be more aware of my real limits so I am more inclined to use less weight and better form than count on someone being able to save my ass when I go past "pushing myself" and start being stupid. The other thing is, when people comment about how much you workout, how often do you hear them use the excuse that they don't have a workout partner? How many of these people who want a workout partner are going to be dependent on you for their motivation??? Screw that. I'm not saying I never work with partners, and I have spent time showing friends how to workout, but I cringe at the thought of "training" with those same friends. Anyone else feel the same?
