If exercises (Dand, Surya namaskar, etc) and yogasanas are to be performed in the morning, which should be done first?
Exercises involve exertion and one necessarily gets tired. Therefore, the evening time is good for exercises as one gets plenty of rest afterwards. In the morning, light exercises such as Surya namaskars, Sarvangasundara Vyayam (free hand exercises) etc. are beneficial. Hence you may practice such light exercises first and Yogabhyas afterwards, keeping a gap of 20 minutes or so between the two. For Yogabhyas, any time is suitable. Nevertheless, the morning time is better. If both strenuous exercises and Yogabhyas have to be done in the morning, it is advisable to do Yogabhyas 20 to 40 minutes after finishing the strenuous exercises.
