3/4 Sit-up

3/4 Sit-up

The 3/4 sit-up is a fantastic exercise that targets your abdominal muscles, primarily your rectus abdominis (the "six-pack" muscles), and also engages your hip flexors. As the name suggests, the 3/4 sit-up is a variation of the traditional sit-up, providing a challenging twist to your core workout routine. Unlike a full sit-up, where the movement involves lying flat on your back and sitting all the way up to touch your toes, the 3/4 sit-up involves raising your torso only about three-quarters of the way. This partial range of motion intensifies the contraction on your abs, making the exercise more effective in targeting those muscles. By engaging your abdominal muscles in a controlled manner, the 3/4 sit-up helps build core strength and stability, enhancing your overall athletic performance and reducing the risk of lower back injuries. Additionally, the exercise also activates your hip flexors, which play a crucial role in various functional movements like walking, running, and lifting. To maximize the benefits of this exercise, it is essential to maintain proper form throughout the movement. Remember to keep your feet flat on the floor, knees bent, and place your hands by the sides of your head. Avoid pulling on your neck or straining your lower back. Instead, focus on using your abdominal muscles to initiate the movement and lift your torso off the ground. Incorporating the 3/4 sit-up into your core workout routine can add variety and challenge, helping you progress toward your fitness goals. However, it is essential to ensure you have a strong and stable core foundation before attempting this exercise to prevent any potential strain or injury. Start with a few repetitions, gradually increasing the intensity and volume as your abdominal strength improves. Remember, like any exercise, it is crucial to listen to your body and avoid any movements that cause pain or discomfort. Enjoy the burn and the results that this powerful abdominal exercise can deliver! Keep challenging yourself to achieve a stronger and more defined core.


  • Lie down on a comfortable exercise mat with your knees bent and your feet flat on the ground, keeping them hip-width apart.
  • Cross your arms over your chest or place your hands behind your head, avoiding interlacing your fingers.
  • Engage your core muscles and slowly lift your upper body off the ground, bringing your shoulder blades off the mat.
  • Continue the movement until you reach a three-quarter seated position, where your torso is about 45 degrees off the ground.
  • Hold the contraction for a brief moment, focusing on squeezing your abdominal muscles.
  • Control the movement as you slowly lower your upper body back down to the starting position, keeping your core engaged throughout.
  • Repeat for the desired number of repetitions, maintaining proper form and control throughout the exercise.

Tips & Tricks

  • Use proper form to engage the core muscles effectively.
  • Start with a shorter range of motion and gradually increase it as you build strength.
  • Incorporate variations such as adding weights or twists to make the exercise more challenging.
  • Focus on breathing control to engage the diaphragm and stabilize the core.
  • Combine 3/4 sit-ups with other core exercises for a complete abdominal workout.
  • Progress gradually by increasing the number of repetitions and sets over time.
  • Maintain a consistent exercise routine to see improvements in core strength.
  • Ensure a neutral spine position and avoid rounding the back during the movement.
