As an airline crew member, I had irregular working hours and I appreciate the wide range of Bikram yoga classes, several times a day, seven days a week. There are also Bikram yoga studios at practically every destination. Bikram yoga is an extremely effective way to balance out work, a way to recharge your batteries and helps you "digest" time differences and sleep better. Bikram yoga helps me maintain and improve my flexibility and strengthens my muscles, especially my back. The 90 minutes of Bikram yoga are also good training for concentration and a good portion of meditation training. I feel full of energy after every class - and have been doing this for more than ten years.
