Bycicle Twisting Crunch

Instructions

1
Lie supine on the floor with knees bent at approximately 90 degrees, feet flat on ground hip-width apart. Place hands behind head with elbows bent and pointing outward. Maintain neutral spine alignment with lower back in contact with floor.
2
Engage core muscles and prepare for movement. Ensure neck remains neutral with hands lightly supporting the head without pulling. Keep feet firmly planted throughout the exercise.
3
Lower your torso by extending legs and returning to starting position in a controlled manner, allowing abdominal muscles to lengthen. Maintain core tension and avoid excessive lumbar extension.
4
Perform a crunching motion by flexing the spine and drawing ribs toward pelvis, lifting upper back and shoulders off floor. Exhale during concentric phase, contracting rectus abdominis maximally before returning to starting position with control.

Overview

When programming for Rectus Abdominis growth, the Bycicle Twisting Crunch stands out as a highly efficient Strength, Cardio choice. Performing this movement with Body weight forces your stabilizer muscles to work in tandem with the primary movers, translating to functional strength and enhanced muscular endurance.

Benefits

  • Promotes balanced muscular development by effectively recruiting the Rectus Abdominis and associated synergists.
  • Utilizes Body weight to create sustained mechanical tension, forcing deep muscle adaptation.
  • Allows for a natural movement path that closely mimics functional daily activities.
  • Acts as a highly scalable Strength, Cardio movement, perfect for both beginners and elite athletes.
  • Reduces the likelihood of Waist injuries by reinforcing connective tissue strength.

Pro Tips

Control the eccentric (lowering) phase of the Bycicle Twisting Crunch for 3-4 seconds to drastically increase time under tension.

Muscle Anatomy

The primary driver is the Rectus Abdominis. However, the movement also recruits Iliopsoas, Rectus Femoris, Obliques, Transverse Abdominis to maintain control of the Body weight.
