Why is it so painful to exercise for 3 minutes?
I'm skinny, weigh 120. I used to exercise 30 minutes a day but recently can only go for 3. After every 3 minute exercise , everything hurts and I feel like I'm going to die. All the bones in my body feel like they're going to fall apart and turn to dust. I don't know why I feel bad so much now, I've been exercising 30 min a day for years, I can hardly do 10 push ups now.
