Final Answer:
Lat pulldowns engage the serratus anterior, addressing scapular winging during push-ups by promoting scapular retraction and protraction, making it the most effective corrective exercise in this case. The option B. is corret.
Step-by-step explanation:
The client's right scapula winging during the lowering phase of a push-up indicates a potential weakness in the serratus anterior muscle, which is responsible for stabilizing the scapula against the ribcage. Lat pulldowns would be the most beneficial corrective exercise in this scenario. During lat pulldowns, the serratus anterior is engaged as a stabilizer, promoting scapular retraction and protraction. This helps address the underlying weakness causing the scapula winging during push-ups.
Firstly, scapular retraction exercises (Option A) primarily target the rhomboids and middle trapezius muscles, which may not effectively address the specific weakness in the serratus anterior associated with scapula winging. Secondly, shoulder shrugs (Option C) mainly target the upper trapezius and levator scapulae, providing limited benefit for the serratus anterior. Lastly, bench press exercises (Option D) primarily involve the pectoral muscles and triceps, with minimal emphasis on scapular stabilization.
In summary, lat pulldowns are the most suitable choice as they specifically engage the serratus anterior, addressing the scapular winging issue during push-ups. Incorporating lat pulldowns into the client's exercise routine can help strengthen the serratus anterior, ultimately improving scapular stability and enhancing overall push-up performance. Therefore option B. is correct.
