Correct answer choice is :
A) Do performance testing prior to setting up your workout routine, stretch before and after each workout, get the proper amount of rest and nutrition, and modify your workout as needed
Explanation:
Strength training increases the power of the muscles, tendons, and even the ligaments and bones. The powerful muscles and tendons help hold the body in precise adjustment and defend the bones and joints when moving or under influence. When you begin a workout routine or start a new exercise plan, start slowly. Then slowly build up the intensity, duration, and frequency. If there is an inequality of agonist and opposition tissues, such as the hamstrings and quadriceps, there is an even more improved risk of injury.
For a warm up during track I usually stretch. I do lunges which help with preparing my legs to run. And for a cool down I stretch again, and do some yoga poses. Cool downs and warm up's are important to prevent injury, or dizziness.

It is important because acupuncture points are places where nerves, muscles, and connective tissue can be stimulated. The stimulation increases blood flow, while also triggering the activity of the body's natural painkillers.
Acupuncture has also been proven effective to help the following conditions:
High and low blood pressure, painful periods, morning sickness, dental pain, tennis elbow, inducing labor, reducing the risk of stroke etc.
It also helps knee, back and neck pain, as well as headaches and migraines.
