Answer:
B. It can cause the muscles to tighten up rather than relax
Step-by-step explanation:
Ballistic stretching is where you stretch the muscle as far as it go (comfortably), then, you bounce, causing that joint to tighten and go even further.
------------------------------------
Ballisitic stetching can tear and damage your muscles. It is not the most recommended at all.
Like stated before, ballistic stretching can cause tearing and damage to our mucles and joints. There is more risk for injury in it than with regular stretching.
Ballistic stretching does the exact opposite of relaxing your muscles. Therefore, the best answer is B.
hope this helps!
