TRX tricep extensions use suspension straps to create a bodyweight skull crusher variation. You face away from the anchor point and lower your body by bending your elbows, then press back up. The further you walk your feet back, the more horizontal your body becomes and the harder the exercise gets.
When to use it
Use for bodyweight tricep isolation.
Who it's for
Intermediate lifters comfortable with TRX.
Face away from the anchor with arms extended, hands at about forehead height. Keep your body rigid like a plank. Lower by bending only at your elbows—do not let them drop or flare. Extend back to start. Adjust difficulty by walking feet forward (easier) or back (harder).

We slot it into the right day with sets, reps, and progression you can follow.
Hold TRX handles facing away from anchor.
Walk feet back to create angle, arms extended forward.
Keep body straight, hands near forehead.
Lower body by bending elbows, keeping them fixed.
Extend elbows to push body back up.
Squeeze triceps at full extension.
The more horizontal your body, the harder it is.
Keep core engaged throughout.
Dont let elbows flare.
Use TRX extensions for bodyweight tricep isolation, during travel, or as part of suspension training circuits. They provide an excellent skull crusher alternative without equipment. Include them when you want strict isolation with scalable difficulty.
Dropping hips - this is a common issue that reduces exercise effectiveness.
Losing hip position during the TRX Tricep Extension shifts the loading pattern away from your Triceps and can compress your lower back. Stay planted and let your Triceps do the work.
Moving whole arm instead of just bending elbows.
Letting your elbows drift wide during the TRX Tricep Extension shifts load onto your shoulder joint instead of your Triceps. Keep them tucked at about 45 degrees to protect your rotator cuff and keep tension where it belongs.
Going too fast which reduces muscle tension and control.
Rushing through the TRX Tricep Extension reduces the time your Triceps spends under tension — which is one of the main drivers of growth. Aim for a controlled 2-second lowering phase on every rep.
Intermediate lifters comfortable with TRX.
Lower reps with heavier weight builds raw strength. Your muscles and nervous system adapt to handle more load over time. This range is best for strength-focused goals.
This rep range keeps your muscles under tension long enough to trigger growth. Most people see the best muscle-building results in this zone. It balances strength and muscle size.
Higher reps with lighter weight builds muscular endurance and improves conditioning. This range is good for joint health and building work capacity.
General guideline: 3 sets of 12-15 reps. Rest 60 seconds.
