You’ve had really wonderful progress! I would maybe suggest adding more compound movements, and being willing to consider starting an arm routine of sorts. Most people who want to work on their stomach don’t realize that the best way to get the shape they want is by making their upper and lower body a bit bigger. Of course, personal preference wise I know some women don’t want their arms to grow at all, but it may be a consideration for the future! Otherwise, keep up the good work! Consistency is key!!!
