The trap-3 raise specifically targets your lower trapezius fibers through an angle between Y-raises and T-raises. Lying face-down on an incline bench, you raise dumbbells at about 135 degrees from your body. This angle isolates the lower traps better than other variations.
When to use it
Use for shoulder prehab and scapular stability work.
Who it's for
Anyone with shoulder issues or seeking prehab work.
Set the bench to about 30-45 degrees. The arm path should be between a Y (straight forward) and a T (straight out)—roughly 135 degrees from your torso. Keep thumbs up. Use extremely light weight, often just 2-5 lbs. You should feel this deep between and below your shoulder blades.

We slot it into the right day with sets, reps, and progression you can follow.
Lie face down on an incline bench set to 30-45 degrees.
Hold light dumbbells with arms hanging straight down.
Turn thumbs up and slightly outward.
Raise arms at a 135-degree angle from your torso (between Y and T).
Squeeze your lower traps at the top position.
Lower with control to the starting position.
This targets the lower trapezius muscle fibers.
Use very light weight as the lower traps are relatively weak.
Essential for scapular stability and shoulder health.
Keep your neck neutral throughout the movement.
Use trap-3 raises when standard Y-raises or T-raises don't seem to hit your lower traps effectively. They're excellent for physical therapy and rehabilitation, or as part of a comprehensive shoulder health routine. The specific angle targets fibers other variations miss.
Using too much weight causing upper trap dominance.
Loading more weight than you can control on the Trap-3 Raise forces compensatory movement patterns that bypass your Lower traps. Drop the weight until you can perform every rep with clean form — your results will actually improve.
Raising arms too high or too low (incorrect angle).
On pulling movements like the Trap-3 Raise, this mistake typically means your arms are doing work that should come from your Lower traps. Initiate every rep by engaging your Lower traps first, then let your arms follow.
Not maintaining the thumbs-up position.
On pulling movements like the Trap-3 Raise, this mistake typically means your arms are doing work that should come from your Lower traps. Initiate every rep by engaging your Lower traps first, then let your arms follow.
Lifting head and losing neutral spine.
Craning your neck during the Trap-3 Raise compresses your cervical spine and can cause nerve impingement. Keep your head in a neutral position — pick a spot to look at and hold it through the set.
Anyone with shoulder issues or seeking prehab work.
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: 2-3 sets of 12-15 reps. Rest 45s.
