The Smith machine decline bench press is a machine-based exercise targeting the chest muscles, particularly the lower pectoral muscles. The Smith machine mimics a barbell but provides more stability. This movement is often performed for moderate to high reps, such as 8-12 reps per set or more, as part of a chest or upper-body workout.
Adds size and strength to the pecs
Targets the lower chest
The bar moves on a track making it easier to get into position and control
May be more shoulder-friendly than a flat bench for certain lifters
Place a decline bench underneath the Smith machine. Now place the barbell at a height that you can reach when lying down and your arms are almost fully extended. Using a pronated grip that is wider than shoulder width, unlock the bar from the rack and hold it straight over you with your arms extended. This will be your starting position.
As you inhale, lower the bar under control by allowing the elbows to flex, lightly contacting the torso.
After a brief pause, bring the bar back to the starting position by extending the elbows, exhaling as you do so.
Repeat the movement for the prescribed amount of repetitions.
When the set is complete, lock the bar back in the rack.
