I just found this news article which explains why you should make balance exercises a part of your workout routine:
A key fitness component often overlooked: balance
A well-rounded fitness routine typically includes three main pillars: cardio (walking, biking, etc.), strength (using machines, dumbbells, bands, etc.) and flexibility (stretching, yoga, etc.)
Balance should be considered the fourth pillar – a “non-negotiable” component of every regimen.
Balance and proprioception are intrinsically linked. Proprioception is the feedback loop between the body and brain; it’s the mind-body connection that allows your brain to know where you are in space and thus how your body should appropriately react. By challenging and training your balance, you also fine-tune your proprioception.
This proprioceptive neurological feedback loop is vital for everything from athletic manoeuvres, to fall prevention, to improved posture, to injury prevention and foot strength.
Improved balance will increase your margin for error with everything – from negotiating uneven terrain as you run, to weaving around another athlete on the field, to picking up heavy objects, to stabilizing yourself so that you don’t fall.
I plan on adding balance board work into my workout starting this coming week.
