Performing the: A Step-by-Step Tutorial Janda Sit up
Have a partner hold your feet down or hook your feet under a sturdy, weighted object. As you do this, you should try to pull your feet up, creating tension in your hamstrings and glutes.
Place your hands behind your head, keeping your elbows wide. This is your starting position.
Begin the exercise by performing a traditional sit up, using your abdominal muscles to lift your upper body towards your knees. Remember to keep your neck relaxed and not to pull on your head.
Lower yourself back down to the starting position slowly, maintaining the tension in your hamstrings and glutes throughout. This completes one repetition. Repeat for the desired number of reps.
