What are common Decline Dumbbell Tricep Extension mistakes to avoid?

Letting elbows flare out wide.

Letting your elbows drift wide during the Decline Dumbbell Tricep Extension shifts load onto your shoulder joint instead of your Triceps (long head). Keep them tucked at about 45 degrees to protect your rotator cuff and keep tension where it belongs.

Moving upper arms during the exercise.

During any pressing movement like the Decline Dumbbell Tricep Extension, this mistake reduces how effectively your Triceps (long head) can produce force. Focus on the muscle you're trying to work — if you can't feel your Triceps (long head) driving the movement, something is off.

Using too heavy dumbbells.

Loading more weight than you can control on the Decline Dumbbell Tricep Extension forces compensatory movement patterns that bypass your Triceps (long head). Drop the weight until you can perform every rep with clean form — your results will actually improve.
