When this exercise?

The dumbbell floor fly is used to develop chest strength with limited shoulder loading. The exercise is suitable within strength training and can also be used in mid-stages of shoulder rehabilitation, when controlled horizontal movement is again possible.

Due to the limited range of motion, this variation is often safer than a fly on a bench. Application, loading and progression should always take place in consultation with a physiotherapist or other qualified professional to ensure that the exercise is safe and tailored to individual load capacity, symptoms and recovery status.
