Description

Frog Crunches is an effective abdominal exercise performed with soles of the feet touching in a frog position. This movement reduces the effect of hip flexors, allowing abdominal muscles to work more in isolation. Targeting the rectus abdominis and lower abdominal muscles, this exercise also helps stretch the inner thigh muscles. It is an excellent movement for developing core strength while increasing hip flexibility. Can be performed by everyone from beginners to advanced level. When done regularly, it provides noticeable tightening and strength increase in the abdominal region.

Step-by-Step Instructions

  1. 1

    Lie on your back, open your knees to the sides and press the soles of your feet together

  2. 2

    Keep your arms extended overhead or crossed in front of your chest

  3. 3

    Exhale, engage your abdominal muscles and lift your upper body off the floor

  4. 4

    Simultaneously pull your knees toward your chest so both upper and lower body work together

  5. 5

    Make a momentary pause at the top of the movement and fully engage your abdominal muscles

  6. 6

    Return to starting position in a controlled manner and repeat

Key Points

  • ✓Bring soles together, open knees to sides into frog position
  • ✓Arms straight overhead or crossed on chest
  • ✓Lift shoulder blades off the floor and squeeze abdominal muscles
  • ✓Leg position should remain stable, only upper body moves

Common Mistakes

  • ✗Moving legs - focus shifts away from abdominal muscles
  • ✗Using momentum to swing - no isolated work
  • ✗Pressing chin to chest - neck muscles get fatigued
  • ✗Half movement without fully lowering down - reduces range of motion
