Overview

If you want to isolate and overload the Rectus Abdominis, the Twisting Crunch Straight Arms is an excellent addition to your routine. The mechanics of this Strength exercise specifically bias the Waist, while the use of Body weight allows for a smooth, natural resistance curve.

Benefits

  • Acts as a highly scalable Strength movement, perfect for both beginners and elite athletes.
  • Significantly enhances the structural integrity and power of the Rectus Abdominis.
  • Utilizes Body weight to create sustained mechanical tension, forcing deep muscle adaptation.

Muscle Anatomy

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