Love your post. It's such a cute ode to back fat
Im sure you heard this before, but you cannot spot reduce fat. Back fat is no different. You have to keep reducing overall body fat and it will eventually come off from the back.
With that said... typically the area we want the fat to melt away from is the last area to go. Our body just like to play games with us

It likes to store fat in its own unique area. For some of us...it's the thighs. Others it is the gut.
You can spot tone your back though. But it does not melt the fat from there. It simply strengthens the muscle (a majorly positive thing!).
Bent Over Rows
Good mornings
Shrugs
Lat Pulldowns
Cable Row
Back Extensions
... all help strengthen the back. But to rid yourself of body fat we must:
1) Eat 5-6 small meals throughout the day. Each meal should be 2-3 hours apart. Each meal should contain one protein and one carb. The first meal should be eaten within an hour after waking.
2) Drink lots of water
3) Rest properly. This means taking at least 24-48 hours between strength training the same muscles, and it also means getting at least 7-8 hours of sleep per night. Lastly, it means taking 1-2 days off from exercising per week.
4) Cardio. This should be done at different intensity levels and different session lengths. Consider doing a low intensity/long session, a high intensity/short session and a few medium intensity/medium length sessions.
5) Strength Training. Strength train each muscle 1-3 times per week. You should lift a proper weight and perform the proper amount of sets/reps for your strength training method.
All of the above things combined will result in fat loss.
