In this video Savvas Giantsis shows you some really useful exercises for building upper body and core strength for your arm balances.
This video with Heather Elton is all about backbending. First of all there is a vinyasa sequence that you can follow to gradually work deeper into your backbends. This is followed by some opening work using props to demonstrate techniques for finding more space and comfort for those that find backbending a challenge.
It is such a common postural pattern nowadays for people to shorten the front of their body by bringing their shoulders or head forward. This can lead to neck pain, head aches and even back pain as well as reduce the quality of your breathing. Here are some simple exercises with minimal equipment that will help ease your body back to a more neutral state.
This is one of my own personal favorites, not easy to get into and out of but you really feel it working to increase the range of motion you have in the upper back (extension) and shoulders (flexion). Great for helping you finding comfort in yoga postures that require those sorts of openings such as Kapotasana, Urdhva Dhanurasana (Upward Facing Wheel) and Pincha Mayurasana (forearm balance).
