Question

If you're trying to get to sleep, you should NOT __________.

Answer 1

D. ) Spend 10 minutes doing yoga before getting into bed

Answer 2

Well for me it always depends to a person. What applies to me doesn't apply to everyone.
But base on this question, spending your 10 minutes doing yoga before you go to bed is not a good practice. Yoga must be done in the morning after you wake up to give your body the energy you need.
