Hi Dougie, it is actually impossible to lose weight/fat at a particular place since losing weight and fat is a whole body process. Therefore, if you want to lose the fat around your butt and thigh, you will need to lose the overall fat in your body. However, you can improve the fat loss around those parts by building muscles. So, you will need to do some strength and resistance training.
I think some trainings that are suitable for you are :
leg raise (front,sides and behind)
My daily routine :
Diet - Follow the free 7 days diet plan from the Calorie Shifting
website (a very useful diet plan
Exercise - Monday, Wednesday, Friday = swimming,
Tuesday, Thursday, Saturday = jogging (around my house), Sunday = Yoga
