TRX Fallout
The TRX fallout is a standing core exercise in which you lean forward on the straps and reach your straight arms overhead, holding your body in one line, then pull back up. It trains the abs and obliques to resist your back arching, with the lats pulling the arms back down.
Also called: Suspension Fallout, TRX Ab Fallout, Standing Suspension Rollout, Suspension Trainer Fallout · Equipment: suspension · Pattern: compound
Step by step
- Set the straps to mid-calf length and stand facing away from the anchor. Hold a handle in each hand with straight arms in front of your hips, palms down.
- Walk your feet back towards the anchor until your body leans forward slightly on the straps.
- Brace your trunk, tuck your pelvis slightly under and squeeze your glutes so your body is one straight line.
- Keeping your arms straight, let the handles travel forward and up while your body leans towards the floor.
- Reach only as far as your low back stays flat and your ribs stay down.
- Press the handles down towards your hips with straight arms to bring your body back to the start.
- Repeat for the set. Step your feet back towards the anchor to make it harder, then step forward to stand up after the last rep.
- Brace first, then reach
- Ribs down, glutes tight
- Arms straight all the way
- Body in one line, heels to head
- Reach only as far as your back stays flat

What goes wrong, and the fix
Low back arching at full reach
Fix: Shorten the reach to where your ribs stay down and your pelvis stays tucked.
Hips piking back
Fix: Keep your hips moving forward with your body as the arms reach.
Bending the arms
Fix: Keep your elbows straight and move from the shoulders.
Feet too close to the anchor for the set
Fix: Step your feet away from the anchor until every rep is controlled.
Rushing the return
Fix: Take about two seconds out and two seconds back.
What the research says
StrengthGeneral fitnessSport performanceEndurance
- Muscle activity — An EMG study found the standing suspension roll-out produced the highest abdominal activity of four suspension core exercises. EMG measures activity, not growth.
- Lever — The further the feet sit back towards the anchor, the longer the lever. A common approach is to progress foot position gradually while the back stays flat.
- Volume — Research links more weekly sets for a muscle to more growth, with diminishing returns.
- Kneeling first — Many programmes use the kneeling version before the standing fallout. There is no research comparing the two.
