The TRX Reverse Crunch is an excellent variation to the traditional reverse crunch movement and can provide for improved trunk stabilizer activation leading to increased effort. Specifically, the exercise has the potential to enhance the strength and endurance of the rectus abdominis (lower fibers), deep core musculature such as the transverse abdominis, external and internal obliques, hip flexors, as well as the shoulder and scapular stabilizers. Due to the increased stabilization demands of the activity, the participant can anticipate improved motor recruitment from core musculature. With regular employment, the exercise can promote improved force coupling between the hips and trunk and as well as enhanced force transfer during compound dynamic exercises. The complexity and challenge associated with maintaining proper form can provide for improvements in total body coordination, balance, and kinesthetic awareness. As with many TRX exercise variations, for a given movement, the total quantity of musculature addressed increases as the movement challenges the transfer of force through multiple segments of the body. The variations to the TRX reverse crunch will further add to the stabilization demands while increasing activation of either the hip abductors or the internal and external obliques, depending on the variation performed. The exercise will potentially improve hip stability and balance by aggressively addressing the commonly weaker segment of the rectus abdominis which can translate to a lower risk of back pain and greater pelvic control.
