Dumbbell Floor Fly
Description
The dumbbell floor fly is a chest isolation exercise performed lying flat on the floor instead of on a bench. The floor stops the dumbbells from descending below your torso, limiting the bottom range and providing a built-in safety stop. It is an excellent variation for lifters with shoulder issues, beginners learning the fly pattern, or anyone training at home without a bench.

Dumbbell Floor Fly Instructions
- Lie flat on the floor with a dumbbell in each hand. Bend your knees with feet flat on the floor.
- Press the dumbbells straight up over your chest with arms fully extended and palms facing each other (neutral grip).
- Brace your core and pull your shoulders down and back into the floor.
- Set a slight bend in your elbows and lock that angle in throughout the lift.
- Lower the dumbbells out to your sides in a wide arc until your upper arms touch the floor.
- Pause briefly with the dumbbells touching the floor — this is the safety stop the bench would not provide.
- Reverse the arc by squeezing your chest to bring the dumbbells back up over your chest.
- Squeeze your chest hard at the top. Repeat for the desired number of reps.
