Decline Dumbbell Bench Press
Chest


Chest / Beginner / Compound (multi-joint)
A bench exercise for the chest, with the front delts, triceps and serratus assisting.
Loads the wrist. Use a load you can control and skip it if it causes pain.
Why it hurts: The lower back hangs into extension and the core stops protecting it.
✓ Instead: Squeeze the glutes and brace as in a plank; the body moves as one piece. Elevate the hands if you cannot hold it.
Why it hurts: It puts the shoulder in an impingement position, especially for many reps.
✓ Instead: Point the elbows back at about 45° so the body and arms form an arrow shape.
Why it hurts: Strains the neck and hides a partial range of motion.
✓ Instead: Keep a neutral neck and lower the chest, not the nose, to the floor.
