Seated crunches are a convenient and effective way to strengthen your abdominal muscles without the need for a mat or lying on the floor. This exercise targets the rectus abdominis while engaging the core for improved stability, posture, and overall functional strength. Perfect for home workouts, office breaks, or gym sessions, seated crunches can be performed almost anywhere.

Instructions

Setup

• Sit on a sturdy chair or bench with your feet flat on the floor, about hip-width apart.

• Sit up tall with your back straight and core engaged.

Hand Placement

• Place your hands lightly behind your head (elbows out) or cross them over your chest for reduced neck strain.

Engage Your Core

• Tighten your abdominal muscles by drawing your belly button towards your spine.

Perform the Crunch

• Lean slightly back, keeping your back straight and avoiding excessive arching.

• Contract your abs to curl your upper body forward, bringing your chest toward your thighs.

• Avoid using your arms or neck; focus solely on engaging your abdominal muscles.

Return to Start

• Slowly return to the starting position without fully relaxing your core.

Repetition

• Perform 12–15 repetitions for 2–3 sets, depending on your fitness level.

Tips for Proper Form

• Maintain Control: Move slowly and deliberately; avoid jerky motions.

• Breathe Properly: Exhale as you crunch forward and inhale as you return.

• Avoid Neck Strain: Keep your neck neutral and avoid pulling on it with your hands.

• Engage the Core: Use your abs to drive the movement, not your hips or back.

• Adjust Difficulty:

  • Beginners: Keep hands on your thighs for support.

  • Advanced: Hold a weight plate or medicine ball at your chest for added resistance.
