Muscles PULL on bone to make them move.
When muscles are over-worked and there is not enough oxygen available to make enough energy to
keep moving they produce lactic acid.
This will allow your muscles to
keep working with low levels of oxygen for a few more minutes.
Lactic acid is responsible for
burning sensation in
active muscles
