the abdominals muscles is to stabilise the pelvis and the lower back region to protect the lower back from injury.
you do not need to work ure abs everyday,if ure a gym person your already working ure abs.exercises like squarts,deadlift,lunges,push ups,chin up's and dips..all you need to do is learn how to activate your core.you can do this by pulling ure
belly button toward your spine while breathing out and then maintaning this abdominal position while controlled breathing.if you ask me il say do a full body workout program that targets all the major muscle groups and also include regular cardiovascular training.and remember to activate your core...set up's are a waste of time
if you have any other questions please feel free to ask me?
