It's not easy to lose thigh fats. Most of my friends already show me their thigh punya fats, they are not fat. So if you have fats around thigh area, is pretty normal. If you are fat, just do jogging cardio. After 3 months, I guarantee your legs are strong. Jogging at least 5 days per week, 45 minutes each.

Jogging = quads, calves, hamstring, glutes (not much)
