Bikram's Beginning Yoga Class is a challenging series of 26 postures (asanas) and two breathing exercises (pranayamas), which is suitable for all ages and levels of ability. Each posture stretches and strengthens specific muscles, ligaments, and joints needed for the next posture. The Bikram method also stimulates the organs, glands, and nerves, moving fresh oxygenated blood to 100% of the body, restoring all systems to a healthy working order. Bikram scientifically designed this 90-minute program to deliver total health through the balancing and strengthening of every system of the body in order to prevent illness, injury, and to limit the effects of aging. In addition, the series of postures combines skills of concentration, patience, determination, and self-control, which lead to increased mental clarity and reduced stress.
