TRX Plank Fallout: how to do it right
In short: The TRX fallout is an anti-extension exercise that loads the rectus abdominis in the lengthened position, as your arms move away overhead.
How to do it, step by step
- 1Standing, TRX handles in hand, arms straight in front of you, body leaning forward in a braced plank.
- 2Slowly move your arms overhead, belly tight, glutes squeezed, without arching your lower back.
- 3Go for the maximum range where you keep your back neutral, that's where abdominal tension explodes.
- 4Brake the opening phase over 2 to 3 seconds, no jerk or bounce.
- 5Return by contracting your abs to bring your arms back toward your chest.
The mistake to avoid
Don't let your hips sag or your back arch: keep your body aligned.
Other common mistakes
- You arch your lower back at the end of the range: reduce the opening and keep your pubis tucked toward your ribs.
- You open too fast like a free fall: slow down to 2-3 seconds to really load the stretch.
- You bend your hips to cheat: keep a straight line from shoulders to pelvis to knees from start to finish.
- You go down until you lose the bracing: stop the range where your back stays neutral.
Muscles worked
- Main:
- Abs
Rectus abdominis: prime mover, it resists extension of the spine. Transverse abdominis and obliques: lock the trunk and stabilize the pelvis. Lats and rear delts: co-contraction to brake the arms on the straps.
What to replace it with
Same muscle, same part of the movement: these exercises do the same job.
Frequently asked questions
How do I do the fallout well?
Standing, handles in hand, arms straight in front of you, body leaning forward in a braced plank. Slowly move your arms overhead, belly tight and glutes squeezed, without arching your lower back. Go for the maximum range where your back stays neutral, then return by contracting your abs to bring your arms back toward your chest.
How far do I open my arms?
You open to the point where your back stays neutral, not one centimeter more. The real criterion isn't distance but keeping your pelvis in place: as soon as the pubis goes forward and the lower back arches, you've passed your range for the day.
Where should I feel it?
You should feel the whole front of your belly, the rectus abdominis first, which resists to keep your spine from going into extension. The obliques and the transverse lock the pelvis, and you'll also feel your back and the back of your shoulders braking the straps. If you feel your lower back, reduce the range.
How fast should I do the movement?
Brake the opening over 2 to 3 seconds, no jerk and no free fall. The whole exercise is in this braking: if you drop fast and catch yourself, you're not loading the abs, you're just playing with momentum.
