to move arm upwards, the biceps contracts. Triceps don't do any work here~

Outwards and upwards
only move upwards
Because when the sun's rays hit the Earth's surface, they make it hot. As we, by whatever means, move upwards, the heat of the Earth's surface will decrease because we move away from it. The higher the altitude, the lower the temperature, up to a certain height, and from there it stabilizes. And this within the terrestrial domain
Downwards
Mount Everest is cold because of the altitude it stands at. The higher you go upwards the colder it gets.
the wind

The load will move upwards.
It's hot, thus less dense, so heavier & colder air pushes it up.
in an upstroke the birds wings move upwards
