Ok. Here's how to do a crunch:
1. Lie down on the floor on your back with your knees bent.
2. Place your hands behind your head with your fingers interlaced so that they support your head.
3. Keeping your feet on the floor, use your stomach muscles to pull your upper body towards your knees.
4. Relax your stomach muscles and let your back slowly lower to the floor.
5. Repeat however many times you want!! :D
Tip: The slower your raise and lower your upper body, the better workout you'll get.
Oh, and for a sit up, it's the same exact thing, except you pull your upper body all the way up until you're sitting upright.
When you do a sit up, you sit all the way up, so that your back is off the floor. When you do a crunch, you only go far enough for your arms to touch your legs, so your lower back will still be on the floor.
Sit up
You have to lie flat on the floor, preferably with a matress below to support your body. Then fold your legs in an inverted V shape. If you cannot let your legs remain on the ground throughout doing the sit-up, you should ask somebody to hold them for you or clasp them against a pole or something like that. Then have your palm clasping your ears (not behind the head).
Crunch
The best form for a crunch is to cross your arms on your chest, grabbing your left shoulder with your right hand and right shoulder with your left hand. Bend your knees and, if necessary, have a partner hold down your feet. You could also hook your toes under a bed or couch. As you use your abdominal muscles to raise your torso, keep your chin pointing up. Raise your torso to about 75 degrees, then slowly back until your shoulders are 1 inch off the ground, and repeat. You don't want to "rest" on each repetition by bringing your torso to vertical on the crunch or back to horizontal on the ground on the release.
GOOD LUCK HOPE THIS HELP!!
lay on your back on the floor with your knees bent and slightly out in front of you. Make sure your lower back is pressing to the floor. Think of trying to press your belly button to the floor. Put your hands behind your head with only your fingers touching your head. With your neck up, like you have a ball under your chin, raise your upper body off of the floor as high as you comfortably can. your arms should be out flat against the floor as well. this is a sit up. you can also use this position to raise your knees up to meet you as well, but make sure your arms/elbows do not come forward, it's really important that your lower back remain pressed to the floor.
Alright, you need to lie down on the floor. Make sure it is a comfortable surface like a carpet or a mat. Now, adjust your feet so they are bent. Feet flat on the floor so you can see your knees right in front of you. You back is on the floor along with your head. Now, fold your arms in an X across your chest. Don't put them behind your head. Try and have your hands touching your shoulders when you cross your arms. Now to do the actual crunch you want to move your body so that your elbows go to your hips. That is the crunch motion. You want to do this motion, the crunch until you feel you can't do another one at all. remember to breathe! Feel good. Be healthy, have fun!
Sit up- Lie on the floor with your knees bent. Your feet should be held down by a friend or a machine at the gym. Your arms should be criss crossed on your chest. One sit up is when your arms (which are flush to your chest) meet your legs.
Crunch- Same position on the floor as a sit up. Hands behind your head this time. With a crunch, only your head and shoulders should come off the floor. I hope that helps.
You need to plant your feet on the floor shoulder width apart with knees in the air for sit up and crunch. For sit up put your hands behind your head or across your chest and find a spot on the ceiling and stare at it to prevent from straining your neck. Then you sit up until your chest almost touches your chest. For crunches do the same only you just lift your shoulders down to your shoulder blades off the floor. On both of these you want to tighten you abs while doing them.
