text: ab training? how often should you do abs? what is a good workout or what some good exercises to build up the abdominal muscles? for the upper, lower, and side abs? do your abs every other day fully and every day do a half workout a full workout should be about 35 to 40 mins. and a half no less than 15 try and go full out for 1 min. intervals with maybe 10 to 40 second rests in between depending on your ability. my favorit's are partner leg throws, and abc leg lifts this is where you lay on your back with your legs straight out in front of you and you spell the letters of the alphabet as far as you can go in capitols try and keep your legs straight and your neck flat on the ground. also do crunches to the sides with your hands across your chest so you dont pull on your neck and make sure never to jerk up your head. otherwise any basic abb workout will probably suit you. just make sure its something you will enjoy doing otherwise you wont get as much out of it. i am a highschool athlete who puts a lot of time into the abs and works with the trainer at my school personely.
