Ab crunches may be simple, but they're a tried-and-true way to wake up your core. Curling your torso just enough to engage those front-of-the-belly muscles helps build strength and stability right where it counts. It's a classic move for bears who want to build a solid middle - whether for climbing, lifting, or just looking strong in the forest clearing.

Instructions

  1. Lie on your back with knees bent and feet flat on the floor, hip-width apart.
  2. Place your hands behind your head or crossed over your chest.
  3. Engage your core and lift your shoulder blades a few inches off the ground, keeping your lower back in contact with the floor.
  4. Pause briefly at the top of the movement, squeezing your abdominal muscles.
  5. Slowly lower your shoulders back to the starting position with control.
  6. Repeat for the desired number of repetitions.

Benefits

  • Strengthens the rectus abdominis (six-pack muscles).
  • Improves core endurance and stability.
  • Helps support better posture and spinal alignment.
  • Can assist in reducing risk of lower back injuries when performed properly.
  • Requires no equipment and can be done anywhere.

Key Points

  • Keep your neck relaxed and avoid pulling on it with your hands.
  • Focus on using your abdominal muscles to lift, not momentum.
  • Keep your lower back pressed into the floor throughout the exercise.
  • Exhale as you crunch up, and inhale as you lower down.
  • Move slowly and with control for maximum effectiveness.

Common Mistakes

  • Pulling on the neck with the hands.
  • Using momentum instead of controlled muscle movement.
  • Lifting too high and engaging hip flexors instead of abs.
  • Letting the lower back lift off the floor.
  • Holding your breath during the exercise.
