The Sun Salutation is perfect for warming up the body and generating an internal heat to prepare the body from inside out.
The flow of poses also helps to raise the heart rate and add an aerobic element to your yoga practice.
Although they were designed to be performed in the morning, facing the direction of the sun, they are ideal to perform at any time.
There are any number of variations but I prefer to use this version (above) for beginners.
Practising 4-6 rounds of Sun Salutations followed by 8-10 breaths in Downward Dog is the ideal way to start your daily home practice.
For a more advanced version replace Plank with Chaturanga and Cobra with Upward Dog and you will be working your core.
Remembering to use the breath to move through each of the poses.
