Losing weight and creating a better bum

Hannahjane123456

I'm 4 foot 11 female and 9 and a half stone and I've got around 2 stone to lose. I do the 4.3 diet but add and another day in and eat 800 calories on them fast days and everyday I eat about 80g of protein.

I do a hour of bike everyday and workout a different body part each days lifting weights. I do my bum twice a week,arms, chest and back.

Anyway is they any point in concentrating on building my bum up so it looks better? or Should I wait till I reach my target weight and cut down on the protein?
