Question

Name the Antagonist for the following Muscles Pectoralis Major, Adductor Magnus, Gastrocnemius, Erector Spinae, Rhomboids, Rectus Femoris, Latissimus Dorsi, Tibialis Anterior. And name and exercise for each one of these Muscles and regression/progression based on exercise variables on Page 246.

Answer 1

An antagonist muscle opposes the action of the prime mover. The antagonists for specific muscles like the Pectoralis Major, Adductor Magnus, and others are usually muscles with opposing actions, and exercises for these can be tailored with progressions and regressions.

Step-by-step explanation:

An antagonist muscle is one that opposes the action of a prime mover. The antagonists for the muscles listed would be: for Pectoralis Major, the antagonistic muscles are the trapezius and the rhomboids; for Adductor Magnus, its antagonist is the gluteus medius (dissected); for Gastrocnemius, the antagonist is the tibialis anterior; the Erector Spinae is opposed by the rectus abdominis and the obliques; the Rhomboids' antagonists are the serratus anterior muscles; for Rectus Femoris, it is the hamstrings; against the Latissimus Dorsi, we have the pectoralis major; and for the Tibialis Anterior, the antagonists are the gastrocnemius and soleus muscles. Exercises for these muscles can vary, such as bench presses for the Pectoralis Major and deadlifts for the Erector Spinae, with progressions and regressions tailored to the individual's capabilities and fitness levels, as would be elaborated on page 246.
