It is all going to come together girl you are still 8 weeks out 12.5 % is a great postion to be in. Your calves look fab. Back is my strong point and I love working it. Make sure you are doing pull ups both closed and wide grip if you can't do body weight do assisted I find pull ups way better then pull downs for developing lats and back width. Also don't for get to deadlift that is going to hit both back and your hams. Tries are always a hard spot for woman. I have been trying to work mine twice a week one heavy session with close grip bench, french press and skull crushers. Then one light seasion rolling DB's press downs etc tons of reps light weight do it tell the muscle burns out.
