Crunch (straight leg-up)

Crunch (straight leg-up)

The Crunch (straight leg-up) is an effective abdominal exercise that targets the rectus abdominis, commonly referred to as the "six-pack" muscles. This exercise specifically focuses on the upper portion of the abs, helping to strengthen and define this area. By adding straight leg raises to the traditional crunch, you are engaging not only the abdominals but also the hip flexors, giving you a more comprehensive core workout. To perform the Crunch (straight leg-up), you start by lying flat on your back on a mat or the floor. Bend your knees and place your feet flat on the ground, hip-width apart. Extend your arms straight above your head or cross them over your chest if you prefer. As you exhale, engage your core and lift your head, neck, and shoulders off the ground towards your knees. Simultaneously, straighten your legs, lifting them towards the ceiling. Hold for a moment at the top, emphasizing the contraction in your abs. Inhale and slowly lower back down to the starting position. Including the Crunch (straight leg-up) in your workout routine can help you strengthen your core muscles, improve posture, and increase overall abdominal definition. However, it's important to remember that spot reduction is not possible, and to see visible results, you should combine this exercise with a balanced diet and regular cardiovascular exercise.


  • Lie flat on your back with your legs extended straight up in the air.
  • Place your hands behind your head, interlocking your fingers.
  • Engage your core by drawing your belly button in towards your spine.
  • Exhale and lift your shoulder blades off the ground while simultaneously lifting your straight legs towards your torso.
  • Pause briefly at the top of the movement, squeezing your abdominal muscles.
  • Inhale and slowly lower your shoulder blades and legs back to the starting position.
  • Repeat for the desired number of repetitions.

Tips & Tricks

  • Engage your core throughout the exercise for maximum effectiveness.
  • Focus on lifting your chest towards the ceiling rather than pulling your neck towards your knees.
  • Maintain a slow and controlled movement to fully engage the abdominal muscles.
  • Breathe out as you contract your abs and lift your legs.
  • Keep your lower back pressed against the floor to avoid straining it.
  • If you feel any discomfort in your neck, try placing your hands behind your head for support.
  • To make the exercise more challenging, add resistance by holding a dumbbell or medicine ball.
  • Remember to warm up before performing crunches to prevent any muscle strains or injuries.
  • Modify the intensity by adjusting the straightness of your legs – the straighter they are, the more challenging the exercise becomes.
  • Ensure proper form and technique to engage the abdominal muscles effectively.
