"Spark and Alignment..."
Can a car with bad alignment still be driven? Yes - but it will never steer to its potential. How about one running on 5 cylinders instead of 6? Yes, it too can get you from point A to point B - but it will never accelerate to its potential.
In an effort to squeeze every bit of performance out of a car, you can try using higher octane gas, putting on expensive tires and or replacing your brake pads, but if that car's alignment and 'spark' are compromised, it'll never perform to the manufacturer's intended specs...likewise with you body.
Organic food, cross fitness exercising and Pilates training are nice additives to squeeze more performance out of your body, but you'll never hit your potential if your spinal alignment and nerve system 'spark' are compromised (subluxated). To get the most out of those extra-health activities, you should be subluxation free.
