If you are a beginner, please start on a low key , rather than to jump to an highly ambitious program like an upstart practicing so many yoga practices one at a time or to practice the tough ones requiring days of practice and skill. You will invite problems then than to enjoy and/or continue yoga. Firstly warm-up exercises are a must before you go for yoga. Suppose a person with no previous experiences of practicing yoga is going to practice head-stand for the first time , that also without any warm-up exercise and who is obese and ‘aged’. Just disastrous! For one having high blood sugar this can be all the more disastrous or even suicidal! So this a word of caution for such
people! You have to take help . Use your common sense that you do not fall and get injured. Your head should be placed on a ‘soft’ surface, like a folded piece of cloth so that your skull is not injured. Before you go for headstand practice the easier forms of exercises!
