The available options are:
a) Push-up plus off a wall → shoulder IR/ER → seated DB press
b) Shoulder IR/ER → push-up plus → seated DB press
c) Shoulder IR/ER → seated DB press → push-up plus
d) High-rep bench press → shoulder IR/ER → abdominal crunch
Answer:
A. Push-up plus off a wall -> shoulder IR/ER -> seated DB press
Explanation:
A push-up plus off a wall is an example of a closed chain exercise as the arm is fixated to a stationary surface.
It also make your shoulder blades to move freely, making serratus anterior stronger, a vital muscle that keeps scapula stable and helps it rotate upward. This in turn reduces shoulder impingement when push-ups plus off a wall is done.
Shoulder IR/ER also helps to correct the imbalance in the rotator muscles of the shoulder.
Also, seated DB press strengthens all muscles of the shoulder in a functional way.
