The Bradford press is a variation of the overhead press and an exercise used to build shoulder strength and muscle.
The exercise is a combination exercise that combines a traditional shoulder press with a behind the neck press. It also uses a partial range of motion to keep constant tension on the shoulders throughout the set.
Behind the neck press variations are often seen as a dated practice since they can put the shoulder in a compromised position, increasing the risk of injury.
If you do not have a fair amount of shoulder mobility, it is not recommended to perform this variation. And even if you do, depending on your reasoning behind the use of this exercise, there may be better variations available for you to use.
