TRX Oblique Crunch

Girl Performing TRX Oblique Crunch

The TRX Oblique Crunch is a very dynamic, somewhat pendular exercise, obviously working the core, along with shoulder stability. The bonus of this exercise is the pendular type of movement, that places more emphasis on the Frontal/ side-to-side axis of movement, rather than just the Saggital /front-to-back direction. The movement can be somewhat dynamic with momentum ensuing, that you can work more on decelerating the movement as opposed to just a regular concentric movement, which is very beneficial in the event of sudden movements be it in sports, or in life, that requires your body to react in this type of manner.

Primary muscles worked

  • chest

Body Part

Body Part:




Step 1: With the TRX straps set at three inches above the ground, place your feet in the stirrups so the tops of your feet are facing the floor.

Step 2: With your hands placed on the floor at shoulders with, begin this exercise from the plank position (abs and glutes engaged, shoulders stacked above wrists, keeping a straight solid line).

Step 3: Begin the movement by engaging your shoulder girdle stability with your scapulae depressed.

Step 4: Shift your weight slightly forward so your shoulders are in front of your hands; at the same time, proceed to bring your knees towards one shoulder, in an arc motion parallel to the floor, focusing on engaging the abdominals (not the hip flexors). You are still maintaining a strong plank position with your core and glutes tight.

Step 5: Return back to the starting plank position, then bring the knees towards the other shoulder, in an arc motion once again.

Step 6: Repeat this arc motion from shoulder to shoulder several times.


How to progress the exercise

A progression of this already advanced exercise would be to hold the pike position longer. This will put more stress on the shoulders, wrists, and hands, as when holding a handstand. Try placing your hands on a balance disc or BOSU for a shoulder stability/balance challenge!

Additional Information

Strong abdominals are needed for this exercise, to avoid overcompensating with the hip flexors.

TRX Body Saw with Crunch

The TRX body saw with crunch may look easy but this subtle movement will make your core burn. It will help you to develop the perfect plank as you rock forward and backwards. You’ll feel your core, abdominals and shoulder muscles working more when you slide back.

TRX Anti-Extension Fallout

The TRX Anti-Extension Fallout is precisely to avoid spinal extension by maintaining a very strong plank throughout the movement. The TRX Kneeling Fallout is an easier version of this exercise and should be mastered before performing the straight legged Fallout.

TRX Mountain Climber

The TRX Mountain Climber exercise begins in a similar position as the Suspended Jackknife. The difference is you are performing a ‘Mountain Climber’ which is alternating knees to chest, as opposed to both at the same time. Great exercise for explosive training, which working shoulder and core stability.
