Answer 1

When you lift something with your arms, especially something out in front of you, the weight is well in front of your spine. The weight will tend to make your back bend forwards. To support that, you hold your breath to create pressure in your abdomen – this becomes a kind of pressure vessel which helps your back muscles keep that bend from happening.
