Does anyone know really good exercises for lower abs and upper inner thighs?

I’m pretty lean but have my curves. I have a big butt and curvy thighs but I only weigh 123 lbs. I have a bit of a roll on my lower abdominals and haha, kind of flappy thighs.

I would like exercises for my lower abs, upper/inner thighs, tone calves, and upper arms. I can’t do a full sit-up but I can do a curl up.

Also any foods I NEED to stay away from will help too!

Thanks soo much!!
I would also like some exercises I can do for my lower back sides of my back just a little bit of a muffin, haha.

OH AND BY THE WAY ALL THESE EXERCISES NEED TO BE “AT HOME” EXERCISES.

Thanks!
