This is one of the many things that we humans have forgotten to do as we've evolved, but stretching regularly is really useful - it eases out the joints, loosens the muscles and helps the circulation.
One of my favourite stretches is the Cat Stretch; it's quick and easy to do and loosens up the entire back, stretching out all the long muscles that run parallel to the spine and mobilising all the little joints between each vertebra. I encourage most of my patients to do it every day, morning and evening - those that do generally feeler looser and easier with less stiffness and fewer aches and pains.
Start off on all fours, hands below your shoulders, knees below your hips. Make sure you're evenly balanced, keep your arms straight and strong and draw your belly button in towards you spine so your tummy doesn't 'sag' down to the floor.
Gently arch your back, pushing your rib cage up to the ceiling, tucking your chin to your chest and your bottom underneath you (think of a dog tucking its tail between its legs!). Hold for a count of three, then gently lower back down to the starting position.
Don't be tempted to arch the other way, sagging in the middle and sticking your bottom and head out, as this can over-arch the lower back and jam all the joints together - keep your back flat with your tummy muscles gently supporting your spine.
Repeat this whole sequence 10 times or so, and do it every morning when you're getting up and last thing before bed. It only takes a couple of minutes and will really help to keep the spine healthy - a bit like cleaning your teeth twice a day keeps your teeth healthy!
Sore knees? You can easily do this kneeling on your bed or on a couple of cushions. If it's still too much for your knees then you can do a 'half cat' - stand facing a wall, place your hands on the wall at shoulder height with your knees slightly bent and gently arch your back. Repeat 10 times, morning and evening.
Obviously, if you find this stretch uncomfortable, painful or difficult to do, please be sensible and don't do it! Email me, or give me a call and we can work out what the problem is.
