Difficulty: Moderately Easy
Step1
Situate yourself on the floor and lie down with your back flat against the floor.
Step2
Bend your knees until they form an inverted V. You may want to experiment with the degree of knee bend until you are comfortable in the position.
Step3
Place your feet firmly and squarely on the floor. It is important to have the feet planted correctly to provide a proper base for the sit-up. Some people use a partner to hold their feet in place and others place the feet into sit-up bars or under something else to make sure they remain planted on the floor.
Step4
Position you hands to side of your head but do not grab or pull the head during a sit up. Some people grab their ears but just placing your hands near the ears should suffice.
Step5
Raise your upper body towards the knees. Move the body slowly and do not use a sudden abrupt movement to raise the upper body.
Step6
Touch your elbows to your knees, hold that position for a second or two, and then lower your upper body back down to the floor. The lowering should move as slowly and carefully as the raising of the body. That way a person does not risk injury and works his abdominal muscles raising and lowering during the sit up.
Step7
Repeat Steps 5 and 6 as desired. Remember to listen to your body and stop if there is pain.
