I have always lost more consistently and effectively using caloric restriction and a low-carb lifestyle. Exercise is necessary, but all my life it didn't seem to affect my weight loss very much, whatever the "experts" might say.
Then a few years ago, I discovered that, for me, exercise CAN help, but, strangely, not necessarily aerobic exercise, nor the usual moderate weight training recommended for women by the "experts".
That is to say, I still include aerobics for their other health benefits, but the main thing I found that contributed to my weight loss was muscle-building exercise. And by that I mean not regular women's weight training, but heavy weight lifting; high weight, low reps. I have lost a lot of weight on high-protein/low-carb with moderate aerobics and the addition of bodybuilding techniques rather than the usually recommended weight training for ladies.
Weight training will build endurance and a little strength, but it will not improve my metabolism anywhere near what adding real muscle mass will do. And contrary to my fears, I didn't bulk up excessively. Women usually don't unless we decide to do so intentionally, take steroids, etc.
Four years ago, I lost four sizes and didn't lose a pound, at first, as the more compact muscles replaced the blobby fat. Then suddenly the weight started falling off. And I wasn't starving myself, just eating moderately low-carb and high protein.
So if you asked me, I'd say either a) focus on reducing your calories/carbs for a few more weeks and keep up an ordinary "women's" workout to get rid of those last ten pounds, or b) up your protein dramatically and start a serious weightlifting program.
My plan is when I reach my goal, to switch to a high protein plan and start bodybuilding again, so I can add muscle to a slim frame and build back a metabolism which has been destroyed by years of yo-yo dieting. I figure, if I can build a base of serious musculature and then switch to a muscle-maintenance workout, I will be able to maintain my weight easier without worrying for the rest of my life about every bite of food I take, because my BMR will be way, way higher than it was before.
That's my goal, anyway!
Good luck an congrats on almost reaching yours!
