Question:
I do 400 situps a day (along with other abdominal exercises). i also play tennis, ride bike+jog 3 X's a week.
if i continue, is this enough for a six pack?
Answers:
Try to cut fat out of your diet, because in addition to beefing up those "six-pack" muscles -- the obliques, I think they're called -- you also want to burn away any ab fat that would hide the definition.
