TRX Fallout
The TRX Fallout is a suspension trainer exercise that challenges core stability and anti-extension strength by mimicking the movement of an ab wheel rollout. It requires you to maintain a rigid plank position while extending your arms overhead, heavily engaging the abdominals and lats.
This movement taxes the core through anti-extension while heavily engaging the lats, so Iridium checks fatigue levels in both muscle groups to ensure you can maintain stability without compensating. The algorithm tracks your performance relative to your current body weight to distinguish true strength gains from body mass fluctuations. If your anterior deltoids or lats are exhausted from recent heavy compound lifts, Iridium may rotate this exercise out to avoid limiting your effective core training volume.
Form Cues
- Squeeze your glutes and brace your abs before starting the movement
- Maintain a perfectly straight line from your ears to your heels
- Keep your arms straight and elbows locked throughout the entire rep
- Exhale forcibly as you press down into the handles to return to the start
- Keep tension on the TRX straps at all times
- Don't allow your lower back to arch or sway towards the floor
- Don't bend your elbows to pull yourself back to the starting position
- Don't let your hips piked backward before your hands return
- Don't shrug your shoulders up towards your ears
- Don't let the straps go slack at the top of the movement
Common Mistakes
- Hyperextending the lumbar spine
- Bending arms to initiate the return
- Leading the return with the hips
- Standing too far forward (insufficient load)
- Holding breath during exertion
Muscles Worked
This exercise primarily targets the rectus abdominis and deep core stabilizers by forcing them to resist spinal extension as the lever arm lengthens. Secondary emphasis is placed on the latissimus dorsi and the long head of the triceps, which must work eccentrically to control the descent and concentrically to pull the arms back down.
