Personal Trainer Questions, please chose ONE of the following ONLY, 250 word essay, ORIGINAL WORK ONLY

 
Choose one of the learning experiences below and write a 250-word essay response.
1.  Perform a chin-up (palms supinated) and determine which muscles are the  prime movers, stabilizers, and synergists. Is there a difference with a  pull-up (palms pronated)? If so, what are the differences? Do as many  chin-ups as possible. Which muscles inhibit your ability to perform more  repetitions? What does this say about the chin-up as an effective  exercise for the latissimus dorsi? List as many variations of pull-ups  and chin-ups as possible. Describe how what you have learned during this  experience will help you in your future training.
2.  Identify and perform ten resistance training exercises. Describe which  phase of the exercise is the eccentric, concentric, and isometric phase  of the movement. At which phase is the muscle the strongest? Why?  Describe how what you have learned during this experience will help you  in your future training endeavors.
3.  List the six fundamental movements of major body segments (Unit 4).  Give an example exercise for each. In addition, identify an exercise  that combines three or more of the primary movements. List the exercise  as well as the movements involved. How will an understanding of  fundamental movements help you in your future training endeavors?
4.  Perform a posture test on yourself and a friend. What deviations do you  observe? What exercises and stretches can correct these deviations?  Discuss the procedure(s) you used, your findings, how you came to your  conclusions, and what your recommendations are. How does an  understanding of posture, posture assessment, and posture correction  help you in your future training endeavors?
Note: If  you find that everyone you test passes the posture test (perceiving  that they have perfect posture) you need to go one step farther. Observe  the person in everyday activity. How does the person stand while  waiting for something? Does the person slouch? Is the person tilting the  pelvis or rounding the shoulders? Perfect posture is quite rare; be  sure your assessment is thorough.
