Step-by-Step Instructions

1. Starting Position

Lie on your back with knees bent at 90 degrees and feet flat on the floor. Extend your arms straight up towards the ceiling.

  • Maintain a neutral spine
  • Press your lower back into the floor

2. Simultaneous Movement

Simultaneously lower one arm towards the floor behind your head and extend the opposite leg straight out towards the floor. Maintain a controlled movement.

  • Engage your core to prevent lower back arching
  • Keep your movements slow and controlled

3. Return to Start

Return to the starting position by bringing the arm and leg back to their initial positions.

  • Maintain core engagement throughout
  • Avoid sudden jerky movements

4. Alternate Sides

Repeat the movement on the opposite side, lowering the other arm and extending the other leg.

  • Maintain a consistent pace
  • Focus on proper form over speed

5. Repetitions

Continue alternating sides for the desired number of repetitions.

  • Listen to your body and stop if you feel pain
  • Maintain deep, controlled breathing

Form Tips

Maintain Neutral Spine

Keep your lower back pressed into the floor throughout the exercise to prevent arching and protect your spine.

Controlled Movement

Avoid jerky movements. Lower your limbs slowly and deliberately, engaging your core to control the movement.

Proper Breathing

Exhale as you lower your limbs and inhale as you return to the starting position. This helps maintain core stability and control.

Common Mistakes

Arching the lower back

Engage your core more intensely and focus on pressing your lower back into the mat. Reduce the range of motion if necessary.

Lifting shoulders off the mat

Keep your shoulders relaxed and gently pressed into the floor. This helps stabilize your upper body and protect your neck.

Using momentum

Perform the exercise slowly and deliberately, focusing on controlled movements rather than speed.

Insufficient core engagement

Focus on tightening your abdominal muscles throughout the exercise. Imagine drawing your navel towards your spine.

Holding breath

Maintain consistent breathing throughout the exercise. Exhale during the exertion phase and inhale during the recovery phase.
