i never felt the burn with abs for a long time. a lot of ab machines do nothing for me, as well... i would recommend doing at least 3 sets of 3 exercises. i do this 3 times a week, and im finally seeing results. ive even seen people swear by doing 3 sets of 5 exercises!granted, i need to get my bodyfat level down to see a really nice 6-pack, but i definately notice a difference.
first off, make sure you are changing the exercises you do! i change them every 2-3 weeks.
this is what i did today:
3 sets of straight leg raises - 48,42,38 reps
3 sets of double crunches - 40,45,33
3 sets of side leg lift things - 9,8,8
i dont really know the names of these exercises but illt ry to explain: double crunches is where i do a crunch, but let my legs go down and up with the crunch, not just my upper body. the side leg lift thigns are like a leg raise, but if you were looking overhead, my legs will go to the right, middle, left, middle, right etc. so it would look like this, \|/ if i had 3 sets of legs. thats the best i can explain it. i just started doing this one, usually i swear by bicycle crunches, if done slowly enough.
you might want to try going slower on the abs. also, sometimes i used to stop working the abs before i had really exhausted the muscle, because at least for me, my abs feel like they are exhausted when i can still do like 10 or 20 reps! as far as "going numb" i know what u mean, i would just do more sets, personally.
i also make sure im focusing on my abs, not the obliques. i get some oblique work in (bicycle crunches usually) but i concentrate on the muscles in the middle more. this workout takes me like 15-20 minutes, but its the only way i can get any results. some times i put in weighted crunches on a machine, but not usually. im not sure if this is what you were looking for, but this is what works for me, i hope it helps...
