More often than not a trainee spends too much time bench pressing compared to other variations of pulling and pushing.
It is a shit exercise in relation to the benefits garnered by most other exercises neglected;
it doesn't really biuld good overall pec strength and flexibility
the anterior deltoids do the load of the work
the triceps are worked, but there are safer exercises to load these muscles
the shoulder blades are pinned against the bench inhibiting proper shoulder movement
its and exercise that builds strength, but too much can and will cause a Miriad of shoulder complications down the track, and that's not what exercise is for, to cause injury.
