Outer Chest Sore After Rear Deltoid Fly Machine

[Andrew]

Any tips on how to prevent my outer chest from being sore after a heavy seshion on the rear deltoid fly machine?

IMO muscle soreness is no type of sign of muscle growth. Muscle soorness is only tiny mico-tears inside the muscle. Once you start working out week by week soreness seems to go away. Pumps aren't really a sign of gains either, pumps are just fluids pumped inside your muscle.

If your outter chest is being worked perhaps you should switch to a closer grip. Wide grip is gains to the "outter portion" of the chest which pushes, and if you would go a closer grip perhaps shoulder width it would be more inner chest.

I think that for flyes, the further back you go, the more your body will use the outter parts of your chest to bring it in initially, and then will switch the stress to a different area of your chest as you come in closer.

So, it could be that the outter area of your chest just isn't as strong yet and can't handle the stress that the other parts of your chest can at the time.

Just a thought tho from how I've felt training, not a scientific reason
