Working out really doesn't take that long. Most studies have shown that a typical non-steroid using weight training session only needs to last 45 minutes to an hour. After that time period, unless you consuming calories during the session the results you can get drop off dramatically from diminishing returns.
I agree that the biggest hurdle with people going to a gym is the intimidation factor. I'm in the gym 4 times/week and love seeing people who start and keep going. I want to tell them how awesome it is that they are doing it, but am never sure if that's the right thing to do some stranger lol.
If you can afford it the personal trainer is a great idea. The only problem is that many PTs plain out suck. I would try to do a session with one before committing to anything long term with a particular person. There are personality and knowledge factors that as a client you want to find out early.
Your story is also very common and is why a friend of mine is opening a gym that will cater to people who need a PT and are generally intimidated about the process. Obviously it will be a smaller niche gym, but I think it will work out pretty well.
General heuristic: If you are not sure, if it is right to approach a stranger, just do it. Really. Talk to them next time.
And don't end your sentences with "lol", please.
And in general your heuristic is correct, but the gym is an odd place. I'm pretty social, but would prefer no one talk to me while working out. I'm usually so busy watching the clock and focusing on the task at hand that I don't want to seem rude to someone by having to eventually ignore them to finish my workout.
(I fear that all the image-substitution of smilies will create a generation of internet users that can't read the original ascii ones...)
As for the complements to a stranger, I did have a couple of random people at the gym say 'you've been working your ass off' or 'you've lost a lot of weight' in a non-creepy way when I was in line at the juice bar and I definitely appreciated it. But everyone's different.
When it comes to random complements it's really me projecting my anti-social tendency while at the gym. I'm there for one reason and it's to work out. I put headphones and generally don't talk or interact with anyone the entire time I'm there. I guess if the opportunity presents itself I'll try and offer a complement in a non-creep way :)
In lower middle class neighborhoods of Jersey City (JSQ), you can talk to others. Ask for a spot or advice on form, tell them "bad form, watch out", whatever. In Manhattan gyms (at least the 2 or 3 I've used), no one talks to anyone else. Ever.
My new gym is a big box gym. It's super nice, and I keep telling a friend of mine that really it's too nice. The people aren't very friendly, but I think that's because there are so many more people working out here that you rarely see the same person enough times to form any relationship. Plus, many people are there to just hang out and act like they are working out. One time I actually overheard a guy ask another guy for a spot and the guy told him no and then walked over to another bench and just sat down. I was stunned and in all my years of working out had never seen someone not help another when asked.
Even in their most competitive days I couldn't imagine Arnold telling Lou no if he needed a spot.
While sudden drops of weightloss right at the start of a major lifestyle change are pretty normal, if you continue at this rate you should talk to your doctor.
When I cut soda from my diet I lost 10lbs in a month. In a month! And then it tailed off and I was depressed because I couldn't sustain it, I had unreasonable expectations. And if you're losing 2lbs a week for a very long period of time, it can be an indicator of underlying medical issues.
I would say 10 lbs a month is about average for someone who is motivated and losing weight.
Much like matwood, I was ~205 at 6' with an athletic build. I wasn't overly fat, but hefty (ok, kinda fat). Running and working out six mornings/week and basketball in the evenings allowed me to drop 2 lbs/week, to a much leaner 165. Coincidentally, I had a doctor visit or two during that time and the doctors never expressed any concern over it.
Fortunately, and I believe this generally for healthy adults, you will reach a plateau. I did so at 165 and never fell below that, even when I increased my running, lifting and other recreational activity.
In short, don't get depressed about the scale. Look in the mirror and keep making body composition changes.
If personal willpower isn't getting it done, I'd suggest team sports. I got into rowing a few years ago, and it's been great. Basketball, soccer/football, tennis can be great sports for consistent quality workouts.
The only thing I'd add - working out is time-consuming, and getting started at a gym is both hard and intimidating. Gyms themselves are counting on you to stop going - that's how they make their money. If you're having trouble getting started, consider saving up your money and getting a personal trainer for a few months. The personal trainer will teach you how to use the equipment properly, get you more comfortable around the gym, and, most importantly, will be so godawful expensive you won't shrug it off and not bother to go to the sessions - the pain of wasting all that money will be too much.
Yes, I know this is silly - but I was getting chunkier and chunkier over the past couple of years and for me that was the only thing that worked. Personal willpower just wasn't getting it done.
