I teach yoga with yoga props, and love it. There I said it. Why? Click here for a blog devoted to the benefits of using them. No matter who you are I can bet that somewhere in your practice, a strategically placed prop will empower and power up your yoga practice.
You can see in this comic that T-Rex has short arms so the blocks help to add length which makes the pose more accessible to him. This means better alignment which = he is going to actually benefit from the asana rather than be overloading his spine, chest, arms etc. Your arms may not be ‘short’ but they might be extra tight.
Basically if the stretch feels too far away, bringing it closer with a well placed prop or two is going to allow you to stay in it longer and it will overall be healthier, so try it next time ~ reduce struggle and compression and increase comfort, stability and strength…so adapt and invite your practice to find you where you are or you are welcome to contact me for private yoga class assistance
