ELI5: Why is it so hard throwing an object straight upwards when lying down?
gpt
When you were a child you took a long time to learn how to throw properly, moving your body in just the right way. Throwing (well) is actually quite a complex action, using lots of muscle groups, and if you try to throw in a particular way without having practiced a lot, for example with your non dominant hand, or lying down, you will tend to just use your arm which gives you far less power and just feels wrong.
