I have to admit I do not understand at all how we strengthen our rear delts. I know the exercises to do, I just don't get how it works.
My experience with the main compound lifts may actually be getting in my way. For those you have a sustained program of varying intensity and volume and you can measure gains. You know where you are trying to go, a higher 1RM, and you know how to measure it.
So for a move like face pulls, what on Earth is the goal? More and more reps? Pain endurance as you work deeper and deeper into the burn? As I said, I'm probably confused because I think of gains in terms of the big compound moves, and don't know how to measure progress for this small muscle.
Like Jeannay, I once believed that compound movements were enough.
All I did for my posterior chain was compound pulling movements.
After developing shoulder problems, I implemented additional isolation posterior chain movements.
It took some time and experimentation but my shoulders are back to normal.
I have a greater understand the value of isolation movements.
Nowhere did i say compound movements are enough. i said IF he wants to progress in weight he should pick a compound movement with rear delts as having the primal mover (rows with elbows high)for it. I Suggest this because many people like to record their progress in weightincreases and compound movements are better suited for this. Doesnt mean he has to use compound movements exclusively. Isolation has a place and is a very important tool.
sorry maybe i miswrote, english is not my native language.
