I'm 15 years old and I'm 5'4. I weight 132 pounds and I'm not sure my body fat %. I've been working out for a few months now and I wanted to know what i could do to work out my back (lower back to be specific) because it seems out of shape compared to the rest of my body. Here are the pictures of my front and back. Thanks
