Great post indiblue
Strength training at a normal healthy weight is basically identical to maintenance in that you don't "see" daily results. You may feel them (feel good, feel 'healthier', more energy, even muscle soreness in the beginning) but you won't see it. I recommend a good front/back/side bikini/undies pose when starting. Now, stay on plan for a full year, take your pics again, and WOW, you will really see it.
With weight loss, you "see" results every day on the scale, whether they are real or not (ie. a 1-2lb weight 'loss' is very likely just water fluctuations). This is what pushes many people through weight loss. You can see in the weight loss support section that people who don't see this change often give up and throw in the towel - even though they can 'feel' daily changes (ie. better nutrition).
This focus on the # at YOUR size is what holds a lot of girls back. Yes, at 300+lbs, seeing weekly/monthly scale weight changes is important, but girl you are NOT overweight! So it's time to brave strength training. Remember that this is for the long term - if you can push yourself to do strength training and stick with it, no matter what the numbers say (I mean obviously if you gain 10-15lbs there's a problem but a 1-2lb fluctuation here & there is no big deal) then you will really thank yourself.
And you will be much better prepared for maintenance. I've maintained for 8 years and trained through 2 pregnancies - believe me, training will help you get through maintenance, which many are sorry to say is actually a lot harder than weight loss.
