Answer:
vastus lateralis
Explanation:
Based on the information provided within the question it can be said that in this scenario the trainer should recognize the vastus lateralis as needing static stretching. This is because this muscle's only task is to extend the lower leg and thus allowing the body to lift itself up from a squatting position. Which is exactly what the client is currently doing in this scenario.
An example for life for an animal and plant are that the both require foods to live. Animals hunt there own food but plants make there own due to photosynthesis. But they are similar because they both require food to continue living. There are many more characteristics but that is just one common one.
