Ask anyone who has a regular Yoga practice that if they have time away from their regular practice, the difference of how they feel.
This difference is not usually a positive difference. The mind can get lazy, more easily irritated and the bodies energy flow gets blocked which can show up in the form of pain, or unwanted sensations in certain areas of the body.
The breathwork involved with Yoga and the Asanas work together for the full body mind connection. The common cry from people when you ask them about starting Yoga is 'I'm not flexible enough to practice yoga', that's why we do Yoga:)
If you never start you will never have the calmer mind, flexibility with the strength you are seeking, along with the awareness to utilise the tools that Yoga gives you.
Yoga helps to promote the calm mind, and the mind can be a complete minefield sometimes. Imagine the mind being a wide open and un-touched field, now it becomes a 'mindfield' where anything is possible.
These tools from Yoga range from conscious breathing when an apparent crisis arrives, to getting up out of a chair or out of a car and engaging the correct muscles to perform these tasks.
Yoga teaches us many, many useful tools which are to be utilised daily for skillfull living.
