Vrksasana (Tree Pose) teaches you to simultaneously press down and feel rooted as you reach tall like the branches of a mighty tree. In this pose, you find a sense of groundedness through the strength of your standing leg. Bringing the sole of your opposite foot to your shin or thigh challenges your balance. Continuously engage your ankles, legs, and core and notice what tiny movements your body might make to help you stay balanced.
By strengthening your legs, glutes, core, and back, Tree Pose can improve your posture and alignment, which is especially helpful if you sit throughout the day.
What makes this pose special is that it teaches you to explore your connection with your body. Maybe one day your lifted foot is positioned closer to your groin. Maybe another day, you leave your foot partially on the ground for balance. Be honest with your limits and learn to honor what your body needs on any given day.
Vrksasana (vrik-SHAH-sah-nah)
vrksa = tree

Place your foot on your calf or keep your toes on the floor and place your heel just above the opposite ankle.

Sit toward the front of a sturdy, armless chair. Bring one leg forward with your knee mostly straight. Bring the other knee out to the side, opening your hip. You can use a block under your lifted foot or simply bring that ankle to the opposite shin. Your arms can be raised into a big V shape. Hold for several breaths, then repeat on the other side.
Pose type: Standing posture
Targets: Lower-body strength
Benefits: Tree Pose is a strengthening posture that can help build confidence. This pose can improve your posture and counteract the effects of prolonged sitting. On your standing leg, this pose strengthens your thigh, buttock (glute), and ankle. On your lifted leg, this pose gently stretches your entire thigh and buttocks.

Challenge yourself by closing your eyes as you balance in Vrksasana. You can also challenge your balance by touching the palms overhead.
“A tidbit I picked up along the way and have often repeated is that stiffer trees are more likely to be felled in a storm; the trees that can bend in the wind are less prone to breaking. I love to remember this in Vrksasana,” says Sage Rountree, author and co-owner of Carolina Yoga Company. “A little sway from side to side is a sign of resilience and an opportunity to find equilibrium in the middle of shifting circumstance.”
These cues will help protect your students from injury and help them have the best experience of the pose:
To prep for Tree Pose, focus on poses that open your hips. Also, practice your drishti to develop the habit of keeping your attention centered in balancing poses.

Several “stories” take place simultaneously in Vrksasana. It is both a balancing pose and, secondarily, a hip opener, explains Ray Long, MD, a board-certified orthopedic surgeon and yoga instructor. The pose also unites the various parts of the body, from the foundation formed by the standing foot through the palms of the lifted hands. Tree Pose asks some parts of you to ascend while others remain rooted to the ground.
In the drawings below, pink muscles are stretching and blue muscles are contracting. The shade of the color represents the force of the stretch and the force of contraction. Darker = stronger.

Straighten the standing leg by activating the quadriceps. The gluteus medius automatically contracts when you balance on one leg. Engage the muscles of the ankle and foot to stabilize the standing leg.
Pay attention to how the other leg feels. The hamstrings activate to bend the knee; the adductor group presses the sole of the foot into the inner thigh of the standing leg; and the hip abductors, gluteals, and deep external rotators contract to draw the knee back and externally rotate the femur. The bent-leg foot pressing into the thigh stabilizes the standing leg.
The pelvis connects to the spine through the erector spinae muscles along the spine. Engage the deltoids, the main shoulder muscles, to lift the arms, and the infraspinati (part of the rotator cuff) to externally rotate the upper arm bones. Draw the shoulders away from the ears with the lower third of the trapezius and press the palms of the hands together evenly.
The balance of the pelvis results from the interplay of various muscles that move the hip—the adductors, abductors, extensors, flexors, and rotators. Move up the body to the back and balance the activation of the erector spinae and quadratus lumborum with that of the abdominal muscles on the front body. Draw the shoulder blades toward the midline and down the back. Then activate the pectoralis minor and serratus anterior muscles to lift the chest.
