The Bicycle Crunch is a highly effective abdominal exercise that targets multiple muscle groups in the core, including the rectus abdominis (front of the abdomen), the obliques (side of the abdomen), and the transverse abdominis (deep core muscles). It is a versatile and challenging exercise that can help strengthen and tone your midsection. In this comprehensive guide, we will explore the technique, benefits, and alternatives to the Bicycle Crunch.

Instructions for Bicycle Crunch


  1. Starting Position: Begin by lying on your back on an exercise mat or a comfortable surface. Place your hands lightly behind your head, elbows pointing outward, and your fingers gently supporting your head. Keep your lower back pressed against the floor by engaging your core muscles.


  1. Leg Movement: Lift both your feet off the ground, bending your knees at a 90-degree angle. Your thighs should be perpendicular to the floor.
  2. Crunch Motion: Simultaneously, perform a crunch by lifting your head, neck, and shoulders off the ground. Your shoulder blades should barely clear the floor.
  3. Bicycle Motion: Begin the “bicycle” motion by extending your right leg out straight while bringing your left knee toward your chest. At the same time, rotate your torso to the right, bringing your left elbow towards your right knee.
  4. Alternate Sides: Reverse the motion by extending your left leg out straight while bringing your right knee towards your chest. Simultaneously, rotate your torso to the left, bringing your right elbow towards your left knee.
  5. Continue: Alternate sides in a pedaling motion, similar to riding a bicycle. Your legs should mimic the pedaling movement while your upper body performs the twisting crunch motion.
  6. Breathing: Exhale as you twist and bring your elbow towards your knee, and inhale as you extend your leg out straight and switch sides.
  7. Repeat: Perform the desired number of repetitions or a set time interval while maintaining proper form.


  • Keep your elbows open and avoid pulling your head with your hands; your hands are there for light support, not for neck pulling.
  • Focus on the quality of the movement rather than speed. Ensure you are feeling the contraction in your abdominal muscles with each twist.
  • Keep your lower back pressed into the floor throughout the exercise to protect your spine.
  • Engage your core muscles continuously to stabilize your torso and support your lower back.


  1. Core Strength: The Bicycle Crunch is one of the most effective exercises for strengthening the entire core, including the front, sides, and deep abdominal muscles.
  2. Oblique Development: The twisting motion in this exercise targets the oblique muscles, helping to create definition and tone in the waistline.
  3. Improves Flexibility: The pedaling motion of the legs helps improve hip flexibility and mobility.
  4. Enhances Coordination: Coordinating the movement of the upper and lower body in a fluid manner can enhance overall coordination and balance.
  5. Calorie Burn: It’s a dynamic exercise that engages multiple muscle groups, making it effective for burning calories and promoting fat loss.
  6. Low Impact: Unlike some high-impact exercises, the Bicycle Crunch is relatively low-impact and places less stress on the joints, making it suitable for a wide range of fitness levels.


While the Bicycle Crunch is a highly effective core exercise, there are alternative movements that can target the same muscle groups and add variety to your core training routine:

  1. Russian Twist: Sit on the floor with your knees bent and feet flat. Lean back slightly and lift your feet off the ground. Hold a weight or medicine ball and twist your torso from side to side, tapping the weight on the ground next to your hip.
  2. Plank: Assume a push-up position with your arms straight and your body in a straight line from head to heels. Engage your core and hold this position for a set time or repetitions.
  3. Leg Raises: Lie on your back with your hands under your hips for support. Lift your legs off the ground while keeping them straight, then lower them back down without letting them touch the ground.
  4. Side Plank: Lie on your side with your elbow directly beneath your shoulder. Lift your hips off the ground to create a straight line from head to heels. Hold this position on each side.
  5. Hanging Leg Raise: If you have access to a pull-up bar, hang from the bar and lift your legs straight up towards your chest, then lower them back down.
  6. Cable Woodchoppers: Stand beside a cable machine with a handle attached to the high pulley. Hold the handle with both hands and twist your torso while pulling the handle diagonally across your body.
  7. Plank with Leg Lift: Perform a plank with your arms extended and your body in a straight line. Lift one leg off the ground and hold it for a few seconds before switching legs.

Incorporating a variety of core exercises into your training routine can help you achieve a well-rounded and strong midsection. Depending on your goals and preferences, you can rotate through these exercises to keep your workouts challenging and effective.

In summary, the Bicycle Crunch is a versatile and effective abdominal exercise that targets the entire core and helps improve strength, flexibility, and coordination. However, it’s essential to perform this exercise with proper form to maximize its benefits and reduce the risk of injury. If you’re new to core training or have any concerns, consider consulting with a fitness professional or personal trainer for guidance and a customized workout plan.
