First day of weight training (routine content)

So I've been doing cardio every day for a little over a month and have lost 13 lbs but started incorporating weight training today. In terms of routine I was thinking:

Monday: arms/core followed by 30 mins of cardio
Tuesday: legs followed by 30 mins of cardio
Wednesday: arms/core followed by 30 mins of cardio
Thursday: legs followed by 30 mins of cardio
Friday: yoga (followed by maybe some cardio?)
Saturday: off

I'm new to weight training so I thought I'd ask here if that's a workable routine. I'm trying to just burn fat right now (need to lose 40 more pounds), and my problem areas are my butt, thighs, and stomach. From the chest up I look really thin (I have a small frame, tiny wrists and fingers and small chested in the boob area) and my calves are pretty thin and toned as well.

Also does anyone have tips on what cardio to do following a day of legs? I usually do treadmill or elliptical but that seems a little daunting on the legs. I was thinking maybe rowing machine but I want my arms to rest that day. Any ideas?


Edit: any tips on workouts that target thights/butt please feel free to post!
