I would like to get 7% of bf
Maintaining 7% for longer than a few weeks is an unrealistic expectation. 7% is typically around the range that competitors are at toward the end of a prep, and this level of conditioning is incredibly hard to sustain. If you plan to reach body fat this low, prepare mentally for a very challenging diet and low energy levels the last 4-5 weeks of dieting, and keep in mind that you most likely won't be able to maintain 7% for very long if you reach that goal.
Unless you're competing, I think ~10-12% is a more realistic goal. At this bf you will look lean and you'll have great definition, but you won't be suffering from low energy levels and feeling depleted all the time. Do you know your current appx. body fat?
