Flex Your Yoga Muscles
Bikram, or hot yoga, is a popular class that is held in a 95- to 100-degree studio, causing profuse sweating and loosening of tight muscles. If you're trying to improve your body's posture and alignment, then try an Iyengar class. It emphasizes form by taking participants through a slow series of poses, concentrating on form.
If you're looking for a class that emphasizes stress reduction and the mental health benefits of yoga, then look for either an Anusara or Kripalu class - these offer meditation, spiritual healing and a positive outlook.
