So if you're interested, my tips for you would be:
- tell your friends/family/coworkers about it! You will not have much time for them during you challenge and you might have to leave work early on occasion to make it to class. If they know that (and why) you are doing this challenge, they will probably be much more understanding/supportive.
- plan your outfits and laundry day! Doing a Bikram Yoga Challenge means tons and tons of laundry. Before you start, figure out how many yoga outfits and yoga towels you have. I personally like to have 4-5 outfits, so I only have to do yoga laundry 2-3 times a week.
- expect dietary changes and plan for them! Even before the challenge starts, stock up for your increased need of water, electrolytes, protein, vitamins, and food in general. You will have less time for quick trips to the grocery store once your challenge starts, so buy as much of what you'll need beforehand. I recommend: yummy spring or mineral water, electrolyte supplements or at least lemon and salt, nuts or whole wheat snacks or protein bars, fruit or multivitamin supplement, snacks to satiate possible increased hunger. Your body needs good nutrition to transform itself!
- plan to concentrate on yourself as much as possible! Don't plan any big trips or changes for the duration of your challenge. It is supposed to be a time to concentrate on yourself (your Self), your body, and your yoga. You will be plenty busy, especially if you work full-time or have other commitments you cannot get out of.
- plan to take class every day; don't plan to do many doubles! I have seen many people miss classes multiple times each week, and then do doubles and triples on multiple (consecutive!) days to catch up. This is not really what a Challenge should look like. A Challenge is meant to be a commitment to focus on your yoga every day, with consistency. No offense to the folks who had to do multiple doubles and triples to make the Challenge. That is great commitment, of course! But is also adds unnecessary anxiety and stress to it, while the point of doing a Challenge is the opposite: de-stressing and adding stability to your life. (This is my understanding of a Challenge, so no offense intended!)
