I have in the past trained rear-delts with back, as Lush said Rowing exercises, pull-downs to the rear to name but a few bring the rear-delts into play.

I'm a great believer in efficient training, previously I have trained

Chest
Shoulders
Tricpes

Legs
Back
Rear Delts
Biceps

Only two sessions aweek but optimises recovery and ensures that smaller muscle groups are not over-trained. Training related muscle groups makes for a super pump.

As with everything, I keep things moving and change my routine around to add variety.

Off on one there sorry guys

Love
