So, how much "stuff" is really necessary to practice yoga? The basic answer: Nothing. You can do nude yoga if you wish (at home, of course). In fact, there's a surprisingly large group of nude yoga enthusiasts.
The more elaborate answer: What you need to feel comfortable and safe. Technically speaking, anything that you bring into the Group X room when you practice yoga is considered to be a "prop," an aid to help you perform your asanas comfortably and safely. What props you need and/or want are entirely up to you. Here are some of the more common props:
A mat. 24 Hour Fitness provides mats in the Group X room. Those mats serve to cushion your elbows and knees from the hardwood floor. They can be very slippery when you are doing standing or balancing poses, so work "off the mat" when you are working with your feet on the floor. Of course, the Group X mats are communal mats; if you feel any reservation about lying on a surface that a strange (or two, or three) has used before you, bring a towel large enough to cover the surface of the mat. Better yet, consider purchasing a "sticky mat" for your own personal use, one that you can bring to class with you and take home to clean as needed. Inexpensive sticky mats can be found at sporting goods stores (they run more money there), in sporting goods departments of major chain retailers (mid-priced), and in second-chance retailers such as TJ Maxx or Marshalls (inexpensive). Ironically, the same mat can cost anywhere from $25.00 to $8.00 depending on the retailer. If you want a special color, a printed design, a longer mat, a softer mat, an eco-friendly mat, you will most likely pay more than the usual sticky mat price. It's your call. Because mats are so frequently used in yoga, there are even secondary items for mats: shoulder straps, shoulder straps with velcro, shoulder bags, waterproof bags, organic mat cleaner, biodegradable mats. The American marketing imagination appears to know no boundaries.
Something to extend your reach. Can't get your fingers past your kneecaps when reaching forward from staff pose? It's helpful to have a device that can act as your arms' extension. The inexpensive solution is to use your hand towel, placing your feet in the loop formed by holding the towel in each hand. If you wish, you can purchase a yoga strap, a sturdy cotton strap several feet in length; there's no more straining to reach those far extremities. Yoga straps can be expensive for what you appear to be buying. If you have a woven cotton belt at home or some wide nylon tie-down straps from a hardware store, you can use these as a strap. Remember, yoga's not about looks, it's about alignment. If a strap or other extension device helps you get into the feel of the pose, then it's helpful for you. Like a personal yoga mat, your strap (or belt, or towel) is only for your use.
Something to cushion your hips. Do your hamstrings and/or inner thighs protest when you are seated in "easy pose"? Just because Sukhasana is called "easy pose" doesn't make it easy if you are used to sitting in chairs most of the time. It's close to impossible to have a good experience if you are feeling discomfort. Create a make-shift pad for your hips with a soft Group X foam mat. By placing the pad under your sit bones, you lessen the tension on your hamstrings. At home, consider sitting on a small cushion.
And then, there are the "built-in, no cost to you" props. Within the Group X room there are several props that you can use to your advantage. Feeling shaky or unsteady doing balancing poses? Move close to a spin bike and use its sturdy frame and handlebars for support. Place your back against the wall to give yourself a solid surface when you do Trikonasana; the firm wall surface will give you a sense of what it means to really move your top shoulder all the way back. The wall is a wonderful place to try out new poses that would seem to be too much when free-standing. Place your hand along the wall to give yourself support and confidence as you explore new asanas.
What's right for you? No props, a few props, occasional props, lots of props? The answer is a matter of individual choice. As you continue in your practice, remember that props serve a purpose--to explore the fullest expression of the pose within the bounds of safety and comfort.
Until next week, namaste,
