Instructions: How To

Sit Up is one of the most common exercises out there. It’s a bodyweight exercise that targets your core. Sit Ups are very similar to Crunches, however, rather than raising just your shoulder blades off the ground, you raise your entire upper body. This gives you a bit more range of motion than Crunches, however you’ll start to lose some tension in your core at the top of the movement.

  1. Lie on your back with your knees bent and your feet flat on the floor either underneath a stable object or from the assistance of a partner.
  2. Place your hands behind your head and keep your torso braced by breathing into your stomach and flexing the abdominal muscles.
  3. Maintain a neutral spine as you flex your hips and lift your back off the floor until your torso is in an upright position.
  4. Keep tension in your abdomen as you lower your torso back to the ground.

Common Mistakes

  • Resting Between Reps

    Keep your core engaged for the duration of the exercise, even between reps. This exercise is designed to add instability that your core needs to compensate for. Keeping your core engaged throughout the exercise will improve the effectiveness of the exercise.
