This bench press variation is highly recommended for anyone with sensitive shoulders or previous injuries.
Unlike a barbell, the arms are not locked into one position with dumbbells, which allows them to move freely about the shoulder joint in their natural path.
In turn, this takes a lot of pressure off the shoulder capsule as well as creates the ability for slight customization for individuals with minor aches and pains.
How to Perform the Dumbbell Bench Press
I prefer to keep the dumbbells at a 45-degree angle to insure that the arms track properly as they lower down to the chest.
Once the inside bell touches the chest, explode back to the top starting position.
Remember this is a Press, not a Fly, so make sure the dumbbells are going straight up and down not flying out wide.
