Generally people prefer an outdoor spotin the park, in the yard, or on the patio but a spot in your bedroom or den may be best for you. Only you know where to be. Set yourself up to succeed. If going outside seems a strain, then know that your perfect spot is inside. Experiment with different times throughout the day for your primary practice.
Most people find it easier to do it first thing, before the busyness of the day takes over.
If this or that does not get done, then you will never practice. Thirty minutes early in the day and then little bits of practice integrated here and there can equal an hour of practice. More is better for improving health or healing an illness. If you are ill, please start slowly. Do not leave the comfort zone.
