If the ballerina wants to improve her leg extension, she should focus on both flexibility and muscle strength. These two should go together. Flexibility alone or the latter will not help improve extensions. Higher extensions are more dependent on the muscles of your legs.

Wide base support will provide you with lower center of gravity, (think how it is easier to stand with two legs compared with standing with one leg)</span>
The options are likely positive or negative. I believe the answer is Positive.
They both will be in the THRZ
175-20=155 which fits in both THRZ
