which exercise works the abs the most? Sit-ups or crunches?

Question

I want to put an ab exercise into my weight sessions, but I'm not sure which one of the THOUSANDS of ab exercises there are to use...I just want to build the ab muscles, I will lose the fat later after I'm done bulking up. So..which exercise would be best for stimulating the abs the most? Or, should I cycle between sit-ups and crunches?

I have an ab lounge 2 and I can feel my abs burn after about 30 of those, so if I can achieve a burn faster on the lounge than normal crunches/sit-ups, then I'll do that. HOWEVER, I DON'T WANT ABS THAT ARE WEIRD LOOKING (ie, wavy instead of two by two like abs should be)

Thanks much.

Answer 1

crunches works more.
sit-ups dont work that much because sit-ups definitely strengthen the abdominal muscles more.
if yooh want to know what kind of crunches are good, try these.
1. Crunches: Lie down on a soft mat or carpet.

Bend your knees so that your feet are flat on the ground. With both hands clasped behind your head, slowly bring your head straight up (not forward), pulling from your abdominal area. Your head only needs to come up far enough for you to feel a complete contraction of the abs. Then allow your head to slowly return to the floor. Repeat. Be sure to do each repetition slowly, with controlled exhalation on each contraction. Do as many crunches as you can in 60 seconds.

2. Reverse Crunches: Start in the same position as with the crunches, but this time cross your legs and slowly bring the knees into your chest as your arms lie flat on the floor. Make sure you feel the lower abs working and not the momentum of your legs moving too fast. A harder, modified version is to take your legs straight up into a 90 degree angle with your body, and push your pelvis upward from the lower abdominal region. Do as many crunches as you can in 60 seconds.

3. Oblique crunches: Start lying on your back with feet flat on the floor. Take one leg and cross it over the other leg, so the ankle of the crossed leg is resting on the thigh of the other leg. Bring the arm on the side of the uncrossed leg behind your head while the other arm rests on your stomach or the floor. Slowly bring the arm behind your head up and twist so the outside of the elbow goes to the outside of the opposite knee. Come down and repeat. Do as many repetitions as you can in 30 seconds. Then switch sides and repeat.

Answer 2

I'm not sure which works abs the most, but I do know that sit ups are bad for your back. So if you don't want back problems later on, stick to crunches.

Answer 3

crunches are toning so they are more for women because we dont want big cubes
sit ups build muscle so do that but not more than 3 times a week
