Hi, I have only just started going Bikram (hot yoga) last week, but will only be able to get to classes once a week after the initial 30 day trial is over. I am just wondering is it beneficial to practice the pranayama breathing in a normal room or is it only beneficial in the hot yoga room? I also go to a gym that has a sauna & steam room, would it be beneficial to practice the breathing in there? That way I could practice 4 – 5 times a week. Thanks.
