I am going to have to suggest perhaps a crossfit type routine where you hit multiple muscles with the routines. Don't be afraid to build leg muscles, often women are afraid of getting bulky from lifting weights and building muscle but it's very difficult to get bulky lifting weights unless you're taking illegal supplements and testosterone boosters. As you build muscle in your legs, the skin will tighten up giving you a much leaner tone look. If you don't want to join a gym, lots of bodyweight Squats and lunges, try high intensity intervals. Try jump Squats and jump lunges. If you're capable, try holding on tothe wall and do iisolated single leg Squats. 15-20 reps is more for a burn and tone type exercise but I recommend heavier weight, maybe wear a backpack with cans of soup or something for extra weight and try and get 10-12 rep range with no more than 30-45 seconds of rest.
I am doing some thigh "thiner" exercises i got from youtube.. the cannel is called XHIT theyre all for women. Im doin the ab one and its working. GD !
Try yoga. It concentrates on stretching and toning muscles. It can make your muscles feel "long and lean".
You may do jogging every morning it will help you a lot. Good luck to you!
