You're right. Who cares? Get on with the tip already!
If you're anything like me you struggle to find time for everything that needs to get done in your day. And I'm guessing that even if you ARE like me, voice practice might not be at the very tip top of your to-do list. So how can you keep caring for your voice without booking off an hour a day to do warmups and relaxation exercises? Well, how much time every day do you spend waiting? For the bus, for your partner to get ready, for school to be over? Use that time!
Maybe you won't be able to get on the floor and start stretching while you wait for the bus (Especially in Vancouver, it's wet! Ick!) but you can absolutely check in with your posture. In fact, that's my favourite way to wait for the bus. I do it every morning and every night. I check the weight distribution on my feet, are my knees locked or soft? Where is my sacrum at? And are my shoulders tensed or hunched? Is my sternum collapsed? Can I lift and open it? I mindfully adjust my posture and then challenge myself to stay aligned until the bus comes.
Or on the bus I practice my breath support exercises: breathing to capacity into my belly and side ribs and out to a very quiet "fff" while I count in my head. Or I just practice breathing deeper. (See how I'm referencing previous tips? They're all relevant people!)
At the office in front of that computer check in with your head/neck relationship. Is your head off your spine, conked off forward or are you balancing your skull lightly on that atlas vertebra? Is your back hunched or straight? Is your jaw clenched? Can you relax it while you work? Working at the office could become relax your jaw time!
These seem like tiny things, but they add up. If you check in with your body regularly, in the little breaks while you're waiting for that page to load, that bus to come or that clock to strike leaving time, you'll be amazed at the cumulative difference in your life. Give it a try! And please, if you have positive results (or negative results, I don't want to discriminate here) please post your findings below. :)
