Don't worry about ab training. Yeh come on and flame me; bastards . It really isn't necessary, since most compound movements recruit the abs to a fair degree; squats, deadlift, pull-up, chin-up, even push ups. If you have good variation in your routine then you really do not need direct ab-work.
And just incase you are a n00b who thinks 1000 situps is the key to a six-pack: it isn't. 2000? No, that wont work either.
However, I also hate the people who say "It's diet, it's diet, do the abs diet, its ace!" They are just rebranding the phrase "toning up" and we all KNOW that that's an evil word.
But it can be done...........
It's just as well that proffessor X can't jump in half way through posts because he would now...
Little would he know that i was going to say:
But it can be done........... by losing fat, and/or gaining muscle.
P.S I sincerely hope you arn't the kid who's 120lbs 15% 5ft 8, wanting to get ripped; because your really bulky now.
Also if you are making time for situps in your workout, you obviously are not working hard enough, or cant be bothered to work hard, or spending TOO long in the gym.
