Ab Crunch
Also known as:Sit upTummy CrunchAbdominal Crunch
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
- Lie on your back with knees bent and feet flat on the floor, hip-width apart.
- Place your hands behind your head or crossed over your chest.
- Engage your core and lift your shoulder blades a few inches off the ground, keeping your lower back in contact with the floor.
- Pause briefly at the top of the movement, squeezing your abdominal muscles.
- Slowly lower your shoulders back to the starting position with control.
- 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.
