Before you begin
Useful tips for practising Hatha – yoga

Wait for 4-5 hours after a heavy meal or 2-3 hours after a light snack. Be realistic. You do not need to wait so long if you feel empty on your stomach earlier, than recommended above.
If possible, go to a toilet before you start.
Practise in loose-fitting clothing and bare feet.
Use a non-slip mat or floor. The floor should not be too cold.
Fold blankets neatly when preparing to use them, as any creases will disturb your practice.
When the weather is warm and pleasant, try to practice outside, in your garden or in a park. Choose relatively even ground. You may be surprised by how fresh air makes you feel more relaxed, which quickens your progress.
Seek advice if you experience difficulties in practice. Your difficulty may be a common one and there is likely to be a solution. In the meantime, avoid straining too much.
Good luck!
