Take a regular movement you do like a push up or jumping up or anything that is useful for you and start doing it with deliberation to do the least amount of effort in each movement. Let your breath start each move (up, down, left , right) and continue past your regular amount or time. Now move your awareness through the body and become aware of the tension that builds within the body as you start to get tired (for example when most people do pull ups on a wall or on a bar they tense their necks to brace the shoulders and loose a lot of power). With the Inhale try to pull this tension to the breath and with the Exhale try to send it out and relax so you can move without harming yourself and continue to work. Do not be fanatic and remember the purpose is to learn something about your own way of doing things.
