Pilates is wonderful exercise for abs. Running will be best for your legs. Squats as well as lunges will shape the actual outer thigh. I did this particular and with a combination of a weight loss plan, I lost 30 pounds, and started to tone up quick!
A series that I use at home as its free and is quite motivational and at times humorous. So far I have gotten more noticeable abs. Hopefully if I keep at it I will achieve a full-on six pack. This guy has a few videos on workouts so I suggest mixing up which one you do per day
