How many six up per week does it take to get a six pack?

Depends on what type of body you have and what type of body you are looking for. If you are looking to get BIG, I would suggest lots of weight exercises (cable crunches, machine crunches, weighted leg raises, etc.), however if you want the six pack abs, stick to high repitions lower weight. Make sure that every rep you feel in every fiber of your upper and lower abs! Hope it helps!
