| I'm a member of the YMCA across the street from where I work and I think it's great. But I agree that gyms vary a lot in their services and attitude. If you're looking for a gym, I wouldn't bother as much with going on line as going to a number of gyms in your area and checking them out. Ask for a free tour. If you can't imagine yourself ever wanting to go back to a particular gym, write it off your list. Ask about programs for new or returning exercisers if that applies to you. You'll find a place that fits.
I like my gym because it has a lot of programs (including, years back, one that I participated in for returning exercisers). Also, unlike a lot of gyms in LA, which seem cater to the steroid-induced (west side, I'm talking about you), my gym welcomes all sorts of ages and body types. It's also in a location and has hours that are convenient to me.
I prefer exercising in a gym because it's more social. Plus, I figure if I have a heart attack, someone will be there to call 911 right away (not always the case with home gyms). Perverse but true.
One final thing: if you're self-conscious, believe me when I say that no one cares what you look like or what your current fitness level is. It doesn't take long to figure out that no matter what your current fitness level is, someone is more fit and someone else is less fit than you. The important thing is to do what you can, which is what every gym goer, regardless of physical condition, is doing. Have fun with it!  |
