AdamFin, thanks for your posts in this thread. They have been encouraging to me!
OK, here goes my story. I've been a member here for several years, but have never posted on the forums until now. First, let me say that I have never worked out at a gym in my life. I was a chubby kid and have always had body issues. The gym, the thought of getting naked in a locker room, and people who were fit and went to the gym, terrified me. In my late teens and through college I started running and maintained a decent weight, but still I wouldn't set foot in a gym. After a back injury, I pretty much gave up all exercise because of the pain and used that as an excuse for my couch potato lifestyle and my weight gain. Since then, I have been fairly healthy yet 20-30 lbs overweight. I am now 50 and I went to the doc 3 weeks ago for a physical and found that I had high blood pressure and my blood sugar was up significantly. The doc wanted to put me on meds right away, but I resisted and cut a deal with him. He told me I had 4 months to lower my weight (at least 30 lbs) and then we would re-check my bloodwork and proceed from there.
I sucked up my fear and embarrassment and joined the gym 2 weeks ago. I had read this thread and it helped me to make the decision to to take the plunge. My heart was literally racing when I went in to join and when I went into the locker room to change for the first time. I've never really understood why I have felt this way about being in a gym, except maybe that I wasn't an athletic kid and always felt inferior to those who were. But I took your advice and decided I was going naked in the locker room and I wasn't going to make that another issue to overcome. The showers are individual stalls and after only 2 weeks I don't give it a second thought walking from my locker to the showers naked or for that matter going into the steam room naked after my workout.
The thing that I have noticed at my gym is that many of the guys do look half-boned and they could care less about it. The first time in the steam room one guy, who looked about 30, got a noticeable erection and the conversation didn't lapse and it really wasn't an issue for anyone. Personally, I don't think I could ever get boned up in the steam room even if I wanted to because of the heat, but that's just me. I also found out (pleasantly) that I am not as small in comparison to others as I always assumed I was-probably on the larger end of average.
I am happy to say that I have lost 5 lbs and I am really enjoying the workouts. I have found that others have been helpful on figuring out the weight machines and the cardio machines. My lifelong fears were completely unfounded.
Sorry this post is so long but I wanted to say thanks for your help in unknowingly overcoming this fear and giving me what has become a great life experience for me. If there are any other guys out there experiencing this kind of fear I would encourage you to take a step out of your comfort zone and just do it!
