For example, Warrior I strengthens and stretches the entire body. It also has a therapeutic effect for people suffering from sciatica. For people who may have shoulder issues, the posture can be modified by simply allowing the arms to lower down (I personally like the version where the palms are touching in front of the heart.) By taking the arms out of the equation, we can focus solely on our foundation, and develop a deeper awareness of our feet, ankles, calves, thighs, and hips. For those who may have extremely tight calves, Warrior I may present a challenge as the back heel needs to be firmly grounded. Alternatively, Crescent lunge, demonstrated here by Judy, is a good option, since the back heel is lifted off the floor. Modifications are the key to enjoy any yoga posture and all the benefits it has to offer.
A few of the Warrior postures benefits:
Increased strength (all over!), stamina, confidence, focus, and body awareness.
Increased range of motion in the hips specifically.
