Sit ups or Crunches

Which is more effective, 500 sit ups or 500 crunches?

Get or make an incline board for sit ups. Then do crunches in sets
of increasing elevation. It'll give your gut a workout you'll never get from
regular situps or crunches.

Neither.

500 of either is a waste of time. If you can do 500, you need to challenge yourself more. Try weighted crunches, slow crunches, incline crunches.

The pros say no more situps, as it can damage your lower back.

I use the George Forman approach - legs at right angles with heels resting on a chair seat.

After an extensive physiological study, the three most effective ab exercises were found to be the following:

Hanging leg ups
Lying bicycles
cruches lying on a medicine ball

Hence, given the choices you give, crunches is the way to go.

BTW, I am 64 and have a six pack and a 30 inch waist.

I shovel snow in the winter, so me back is already in poop shape. Ive been doing situps, but i dont think im doing them right. How exactly do you do a Lying bicycle? Should my hands be somewhere, behind my head?

Basically you lie on your back, put your hands either behind your head or alongside your head (don't pull on your neck with your hands - it can strain your neck), you raise your legs, and alternately bring on knee back as far as you can with lower legs parallel to the floor, and bring the opposite elbow towards the knee - ideally touching. You continue to alternate legs and arms. Your upper back, neck and head are off the ground. I have a delicate lower back, and have never bothered it doing any of the three exercises I allude to. Regular situps, however, can in fact strain the low back.

500 is way too much. try 3 sets of 25 or 30, and if that gets easy, start adding in the bicycle crunches and hanging leg raises. stay away from sit ups if you have a bad back, crunches get the same work accomplished

This is a concept many do not understand. The abs are no different than any other muscle group. Do you do 500 reps of curls - I don't think so! Muscles also need time to respond to stimulation - that means that you don't do abs every day. I work mine twice a week - sometimes once with great results.

A legup or kneeup is accomplished by hanging from something and either bringing your knees up as high as possible for repetitiions or bringing the legs up as high as possible. I have two devices that hang from my Smith Machine, and my upper arms fit in them supporting my body. It is a great lower ab workout - the area probably most neglected.

Some 15 years ago we upgraded to a particular cable weight machine because it had a cable right behind the head area when your in the sitting position. I use that to do sitting-crunches with 80 pounds. You not only build muscle mass with weight, but you gain almost as much endurance as the high rep/low-weight regime. It does bulk-up the mid-section, but I've never been into the body-beautiful thing.

My objective to build core-strength to protect my spine/back when lifting awkward things like an 80 lb canoe in high winds or carrying two portage-packs some times weighing over a hundred pounds total. Though we haven't taken a wilderness canoe trip in some years now, I maintain the program to keep me well when I do silly things like go over the handlebars.

They work the complete ab area, but favor the lower abs. After completing those, do a couple sets of scrunches just bringing your upper back off the floor, don't bend your neck. It is like trying to bring your face towards the ceiling. Do not pull on your neck - gently rest your hands either alongside your face or on the back of your head without exerting any force with your arms. That will favor the upper abs, and give you a complete ab workout. The ideal would be to do all three exercises when you work abs, but sometimes the leg or knee ups is not practical without proper equipment.

Interesting - I have been doing ab work for years, and just recently have I experienced the same phenomenon when doing my ab work.

It's best to exercise in the AM if you can, according to the research types. Exercising too late in the day interferes with sound sleep. Exercising too soon after a meal will upset the stomach. In Chris Carmichael's new nutrition book, he provides recommendations on meal size vs. time before exercise.

Before retirement, I got up @ 0430 to exercise and get to work before 0700. I exercised before I ate breakfast, but I did gulpdown some fast burning carbos like jam. Now, I still get up the same hour, but I have time too eat and digest a little. That raises the energy level somewhat.

Too maximize rest which is a critical element in any training program, it's best to rise at the same hour every day, seven days a week. If you stay up late the previous night, you'll still have the max energy during the day if you get up at the same time. The extra fatigue will best be handled by going to bed earlier the following night.
