Eka Pada Koundinyasana also known as albatross or hurdler pose improves balance and core strength, stretches the hamstrings and groins, and strengthens the arms. Before You Begin: 1. Take some time to get used to the feeling of supporting the front leg on your arm before trying to lift the back leg. You can also try this keeping the front leg bent while floating the back leg straight. 2. Practice chaturanga and plank in preparation. These will help you strengthen your arms and core. Once you have a feeling for your center of gravity in basic arm balances like crow, more advanced ones become accessible. Advanced Variations 1. If you have been practicing with the right elbow tucked under your body for awhile, work on bringing it out so that it hugs your right side instead. 2. Try jumping back to chaturanga.
