Whats the difference between crunches and sit ups??

Answer 1

A sit up is when your upper body rises off the floor completely and you are sitting on your bottom and a crunch is when only your shoulders come off the floor approx 4- 6 inches. Crunches use only your abdominals and situps use your hip flexor muscles as well as your abdominals.
your abdominal muscles only have a small range of movement and therefore cannot lift your upper body completely off the floor without the help of your hip flexors.

Answer 2

In sit down-up your ft stay on the floor and also you bypass from the floor for your knees. This oftentimes calls for some thing conserving your ft down. Crunchies are even as your ft are interior the are and also you roll as a lot as meet your knees. the suited weight for women that are 5'2" is supposedly everywhere between 103-136 pounds. It relies upon on a lot of diverse factors and it must be good to search for suggestion from a school nurse to grant you the perfect theory specifically for you.

Answer 3

In doing sit-ups your feet never come off the floor and your back comes up completely. In doing crunches your feet come off the floor and your back while it does come up off the floor it does not come completely up as in sit-up. They also both work in different ways as in muscles building and toning.

Answer 4

in crunches your lower back never comes off the floor...in situps it does

Answer 5

They both work your abs, but full sit-ups are bad for your lower back.
