I've been noticing that they are lagging behind the rest of the deltoids. I usually try to do them when I work out my back.
Does anyone have any good exercises for the posterior delts? The traditional bent over ones just don't do it for me.
Normally the go-to exercise would be bent raises, but if you have a hard time feeling them try bent cable raises, using a single rope handle and a neutral grip.
Focus on form-if you go too heavy you will work the surrounding muscles at the expense of your rear delts.
You also might consider doing them with shoulders. This will give you better focus, and a little more frequency (indirect with back, plus shoulder day).
Delts are a high percentage of ST fibers and can take frequent work and recovery.
