Do off-balanced or balancing exercises to become aware of your body and also to help warm up:
Stand on one leg and pull knee up with opposite hand in the air. Balancing exercises help you to become aware of and engage your core.
Balance training allows you to fine-tune your senses and your core. For example, standing on one leg without looking down and then extending forward creates a message to your nerve receptors in your muscles and skin to send to your brain telling you if you feel steady or not.
Proprioception also helps prevent sports injuries during working out or even taking a casual stroll through the mall. Without good Proprioception you will lose your balance and be more perceptible to injury.
