After meeting with a personal trainer, who is also a nutritionist, I'm following a balanced eating plan (protein, carbs and good fats at each meal) and lifting weights six times a week (splits) instead of my twice a week full body workout. I also do hydrofit (deep water aerobics) four times a week plus walk the dog. Walking the dog is kind of a start/stop sort of thing mostly--he's male ('nuf said, right?)--but sometimes I can yank him away from a bush and go at a good clip.
I was hoping this was going to kickstart my weight loss, but after one week of my new weight lifting regimen, I've stayed the same on the scale. I'm hoping it's muscles retaining water, but, frankly, I'm getting a touch discouraged. Any helpful hints? Words of encouragement much appreciated! I really would like to reach my goal of 100 lbs. lost by the end of the year, which, unfortunately, is approaching pretty quickly.

Give yourself 8-10 weeks. I know...patience.....
Weight lifting definitely has made me look a lot smaller than my weight indicates, and my clothing size reflects that. But. . .I so badly want that danged scale to move.
