I want toned, sculpted legs and butt…please help :)?

I am female weighing 139 lbs. I have just started working out again (4 weeks so far). I have lost 9 pounds by doing 30 min of cardio (elliptical or stationary bike) mixed with some lower body strength exercises (leg presses, leg lifts, some squats). Also, I have been increasing the resistance on my bike to the point where I can feel the burn. My question is, what is the best thing I can do to sculpt my legs and keep my butt firm and raised. I have been blessed with a "bubble butt" but I would like to tone it some more.
Oh, and running is not an option…I have accepted that I am just no runner. Thanks for any tips or suggestions!

I can answer this!! I used to have a hella cute shape but 2 babies flipped the script. but hey for the butt muscles do a squat with both your legs together and have your arms stretched out in front of you after you come up from the squat kick back your left leg to where your butt muscle tightens you want to alternate between your legs and do a set of at least 20 or a even amount for each leg. for your legs do lunges as well as continue with what you are already doing!
