Answer:
B
Step-by-step explanation:
Dynamic stretching examples: lunges or even walking lunges
do it now to understand the defination
controlled movements that prepare your muscles, ligaments and other soft tissues for performance and safety. used in warm up
thats why the answer is B
you control your range and may you feel stretch at specific range of motion and your friend do it with either more or less ROM and feel stretch - so the degree is you feel stretch according the tight your muscle is ... but if you do lunges with repetition may be at the end of a program you can not feel any stretch if you do the same range (you can simple mark it with a distance on your mat ) so you will expand your leg or increase your ROM to feel stretch .
dynamic stretch is moving your joints through their full range of motion.
Static stretching requires you to move a muscle to the end of its range of motion, and to maintain that position without pain for 20 to 45 seconds.
