Why can't I feel the soreness after ab workout?
After a heavy workout session my arms etc all feel the fatigue, but not the abs. During the workout I could feel it, to the point where I maxed them out and could do no more reps. I also tried adding resistance weight (those crunch machines in gym) but it seems I could only take so much without being forced to stress other body parts such as waist.
Then after like 20 minutes the abs just don't feel that soreness any more while the arms can feel it for easily a couple of days. Is this normal? I really want to improve my abs but it seems I'm stuck here.
