Kindly Help me understand these Rear Delt Movements - Side Lying Rear Delt Fly (Powel Raise) Vs Supine Lying Dumbbell Reverse Fly
Hello SBS Crowd! I'm beginning to develop an interest in Kinesiology, and I'm particularly interested in the subtle differences between these 2 movements
Both are Single Arm movements, and both perform Horizontal Abduction due to moving your arm across the body, but in one the body is parallel to the ground and in the other, it's perpendicular
How does this small change in body position affect the deltoid segments being worked?
It's my understanding that in the Flat Lying version, the rear delt is loaded in the most stretched aspect, while in the Powel Raise, it's loaded in the mid range
However, in the Powel Raise, if you raise your arms in the scapular plane, you hit the Lateral Delt. I actually got the sickest pump when I tried these
What is your guys' opinion? What are some other things I might be missing, and ultimately which is better for progressive overload? In my experience, I couldn't use heavy weight on my rear Delts as I feel momentum or other muscles taking over
Obviously, a cable or machine would get the job done easier but I'm purely interested in learning and implementing these free weight versions. I'd appreciate the help, thanks!
