The Ultimate Female Training Guide: Weeks 9-12 During weeks 9-12, you will be lifting in the 4-6 rep range. What this means is that you want to complete at least 4 reps but no more than 6 reps for each set. If you cannot complete 4 reps, then the weight is too heavy and you should decrease the load. If you can complete more than 6 reps, then the weight is too light and you should increase the load. This phase of the 12-week program is going to be very challenging and produce accelerated results.
