I'm currently cutting right now and have gone from about 20% body fat down to 18% in 7 weeks. Most of my fat is in my gut/stomach, I weigh 163 and have a 33 inch waist (slight beer belly). I've read on here that it's basically pointless to do any ab workout until bodyfat % is low, otherwise I'd be wasting my time due to the fact that my ab muscles would still be hidden underneath all the fat. Is this true? At what point (body fat %) should I start to workout abs?
