Question: how many sets of reps should you do for toning?
Answer: Females trying to tone should do two sets of 10 to 15 reps each at a "Moderately Heavy" weight. You will build muscle tone, but the high number of reps will keep you from loading on excess weight, which would make you bulk up. If you are a female who tends to bulk up, increase the reps to 15 to 20 per set .
