I wouldnt say that,abs are just like the other normal muscles.Every second day is fine.Do a day in between as a rest.
Doing p90x ab ripper x every other day?
Doing just the ab exercises won't do much. You need to be eating right and burning calories. That's why the ab ripper x workout is set up for you to do after your body is warmed up 3x a week. find out more from my website
Your muscles build when you rest,therefore I say do it everyday. Doing it everyday will be good for you.
Best of luck
You can get insane results, yes.
Can I get good results if I do it every other day. Like do it one day and rest the next day ? Just that exercise alone
