Dear Sir Shri S Haque. I think, from the timing you have given, you have lot of time; hence this suggestion. Try to view programmes of Live Pranayam & Yoga under the able guidance of Swami Ramdevji of Pathanjali Yoga University, Uttaranchal. In the morning between 6.00 to 8.00 and in the evening between 20.00 to 21.00 Hrs. daily on AASTHA CHANNEL. Please have patience; try to see, listen and understand what Swamiji says and does; also listen to the reactions from hundreds of people who have already benefitted from Pranayam & Yoga under swamiji's guidances. My experience says, for you Sir, it is better to begin with atleast 5 to 10 minutes "Bhatsika", 15 minutes each daily "Kapalbhathi" & Anulom Vilom", and 5 minutes each "Bhramari" and "Udgeeth"; all are Pranayams. If possible, try to reduce intake of Non-vegetarian items; instead have more fruit salads and milk without fat daily. I am 60 Years old and have been practising "Pranayams" since last fifteen months. I could avoid taking diabetics pills since last 6 months and I am perfectly alright immune to any disease in the world; this much confidence I could gain just by practising "Pranayam" regularly. God Bless u Sir..
