How many reps should be in each lunge set?
This is really a matter of personal preference, although there are some general ground rules that you should follow. For example, sets are meant to be high intensity and short so that you can specialize and concentrate all of your effort into the muscle groups that you are trying to work. For this reason, 5-10 reps per set are usually called for, although experienced trainers might recommend more to people that have shown a particularly impressive ability in endurance.
