Frog Crunch

Description

How to Do Frog Crunch

1. 1
   Setup

   Lie supine on the floor, flatten your lower back, and bring the soles of your feet together. Let your knees fall open to the sides in a 'frog' position, and place your hands lightly behind your head or crossed over your chest.

2. 2
   Setup

   Engage your core slightly, ensuring your lower back remains pressed into the floor throughout the entire movement to protect your spine.

3. 3

   Exhale as you slowly curl your head, shoulders, and upper back off the floor, drawing your rib cage towards your pelvis.

4. 4

   Focus on contracting your rectus abdominis, maintaining the 'frog' leg position with knees wide and feet together.

5. 5

   Inhale as you slowly and with control lower your upper body back down to the starting position, maintaining core engagement to prevent your back from arching.

Tips

• Maintain the 'frog' leg position throughout the entire movement to maximize adductor engagement and stabilize the lower body, preventing unnecessary movement.
• Focus on initiating the crunch from your core, imagining your belly button pulling towards your spine, rather than pulling with your neck.
• Control both the upward and downward phases of the crunch; avoid using momentum to lift or drop your torso, which reduces muscle activation.
• Keep a slight space (about the size of an apple) between your chin and chest to prevent neck strain, especially if your hands are behind your head.

Common Mistakes

• ×Arching the lower back during the crunch reduces abdominal engagement and can strain the spine; ensure your lower back stays pressed into the floor by actively engaging your core.
• ×Pulling on the neck with hands behind the head can cause cervical strain; instead, use your abdominal muscles to lift your torso and keep a neutral neck position.
• ×Rushing the movement and using momentum diminishes muscle activation; perform the crunch slowly and with control, focusing on the mind-muscle connection to target the rectus abdominis effectively.
