The first "5" in the equation represents the 5 people that you call our friends, associates, etc. I suggest that you make a list of the 5 people that you associate with on a regular basis, and then take a good look at it to see if they either have goals similar to yours or are progressing towards the achievement of a goal similar to your 5-year vision. A major key to unlock the secret to your future is to be 110% conscious of the fact that you will ultimately become who you associate with.
The usual lightweight clothing, anti-sweat athletic wear that dries quickly will do just great. For men its light tees with shorts and women can wear a tank top or sports bra with shorts or lightweight pilates memphis yoga-style pants.
There are a few other choices that exist to cover your Bikram yoga needs. There are cotton yoga rugs that are apparently quite good in these types of conditions. And their history substantiates this too given they have been used longer then anything else on the market, and in places like India and abroad. The cotton yoga mats are woven. They give good cushioning combined with good traction. Once there is a bit of moisture your hands and feet will adhere really well. The other mat that may work well for you is the Lululemon Hot Yogi Mat. This mat, although not specific to Bikram yoga, would work well. It is priced really well at $35 for all the great qualities that it has to offer.
There are more people enjoying Bikram yoga because it can help people get exercise, but it also release toxins from the body. It's done in a heated room, which means people sweat in excess amounts. A big Bikram pilates mat is needed to handle all of the moisture.
Let me assure you, building a successful hot yoga business already has a long held proven formula. It has a blueprint that is easy to follow, and if you follow that blueprint step by step you will attract Yoga students, have a healthy flow of income and still have time for yourself and loved ones. This is the right way, the ethical way!
This is especially true for those who live in very cold climates. Get there at least 10 minutes earlier than the scheduled time of the class so you'll have plenty of time to sit in the hot room. This is necessary for warming up the muscles. As you know, warm ups are very important during workout as they prepare the muscles to minimize injuries. For a quicker warm up, do a few sun salutation poses.
