Pam I hit the gym 2 days 1 day 2 days my split is like this i found it seems to work the best Legs+Abs, Shoulders+calves+obliques, REST, Back+biceps+abs, Chest+triceps+Obliques REST and i rotate Heavy legs light back Heavy Shoulders light chest and swap the next cycle. I also walk every day steady start cardio 35 min fasted. Will increase this as time goes on. If you are lean you need to concentrate on heavy compound exercises to get some muscle (make sure you up your protein as well) i would also not walk if you want to stock up let your muscles heal, dont be afraid to go heavy and dont forget the big exercises Squats, deadlifts, incline bench, bench (especially for women) shoulder press (both) to make sure you get your rear delts. Also I always include (never miss them) Walking lunges mid weight to light weight unfortunately us women tend to hold junk in the trunk, I also do lots of crap for my hamstrings they just never want to be seen. If you want my routine I can post it up for you but i really like to mix it up alot to shock my muscles.
