Lying Bicycle Crunches are a great exercise to target your abs and obliques. Here are the steps to perform them:

  1. Lie on your back with your legs extended and your hands behind your head.
  2. Lift your shoulders and head off the floor and bring your right knee towards your chest while twisting your left elbow to meet it.
  3. Switch sides and repeat the movement with your left knee and right elbow.
  4. Keep alternating sides in a fluid motion, as if you are pedaling a bicycle.
  5. Do as many reps as you can in a set time or until you feel the burn in your core.

Introduction

The Lying Bicycle Crunch is a core exercise that targets the abdominal muscles, specifically the obliques. Its primary benefit lies in strengthening and sculpting these muscles, as well as improving stability and balance. It's particularly effective for those seeking to build a strong, defined core, and it also helps reduce the risk of lower back pain by engaging the abs during movement. The exercise involves lying on the floor with legs extended and cycling them in a pedaling motion while simultaneously twisting the upper body sideways.

Muscles Worked

  • Primary: Abdominals (Rectus abdominis, Transverse abdominis, and Obliques)
  • Secondary: Hip flexors (Iliopsoas), Lower back muscles (Erector spinae)

How to Do It (Step-by-Step)

  1. Lie flat on your back with legs extended and arms behind your head.
  2. Lift your shoulders, upper back, and legs off the ground while simultaneously twisting at the waist to bring your right elbow toward your left knee and vice versa.
  3. Keep your core engaged throughout the movement, maintain a small gap between your low back and the floor, and avoid pulling on your neck with your arms.

Tip: Maintain slow and controlled movements for maximum effectiveness and to prevent injury.

Rep & Rest Guidelines

  • Strength: 4–6 reps, 2–3 min rest
  • Hypertrophy: 8–12 reps, 60–90 sec rest
  • Endurance: 12–20 reps, 30–60 sec rest

Form Tips

  • Maintain a flat back: Keep your lower back pressed against the floor throughout the exercise to avoid injury and ensure proper spinal alignment.
  • Bend elbows and bring hands close to the head, but not pulling on it: This helps engage the abdominal muscles more effectively during the crunch, reducing strain on the neck and shoulders.
  • Exhale while contracting the abdominals and inhale while relaxing them: Proper breathing during exercise can help you perform each repetition efficiently and effectively, reducing fatigue and improving overall performance.

When to Use It

  • Improving Lower Abdominal Strength: Lying bicycle crunches focus on the lower abs, making them an effective exercise for strengthening this area.
  • Enhancing Core Stability: This exercise helps improve core stability by engaging multiple abdominal muscles simultaneously.
  • Targeting Oblique Muscles: The rotational movement of lying bicycle crunches targets the obliques, aiding in side-to-side core strength.
