Inner thigh muscles(lengthening)

These muscles run along the inside of your thighs, connecting your pelvis to your inner knee and upper shin. In Skandasana, the inner thigh muscles of the straight leg undergo a significant, sustained stretch, particularly the gracilis and adductor magnus, lengthening their fibers through eccentric loading. This release not only improves hip mobility and flexibility but also helps to unwind chronic groin tension, which in yogic philosophy, is often associated with a constricted root chakra (Muladhara) and feelings of insecurity or ungroundedness.

Hamstrings(lengthening)

The hamstrings, located at the back of the thighs from your sitting bones to just below the knee, receive a deep, active stretch in the straight leg. This action helps to elongate these often-tight muscles, which commonly contribute to lower back tension and restrict full hip flexion. Energetically, releasing the hamstrings helps to free the flow of apana vayu, the downward-moving energy, promoting a sense of groundedness and allowing for the release of stagnant energy in the pelvic region.

Front thigh muscles(strengthening)

In the bent leg, the quadriceps muscles on the front of the thigh are powerfully engaged, working eccentrically to control the deep lunge and protect the knee joint. This sustained activation builds strength and endurance in the thigh, creating a stable and resilient foundation for the pose. In the straight leg, the quadriceps are actively engaged to lift the kneecap, ensuring the leg remains strong and extended, which cultivates a sense of steady determination and focused energy.

Knee Injury

Deep flexion or rotation at the knee can strain ligaments, meniscus, or cartilage, especially in a compromised joint.

Do not allow the knee to travel beyond the ankle; keep weight evenly distributed and use a block under the hand for support.

Hamstring Injury

Aggressive stretching of a torn or strained hamstring can reinjure muscle fibres — the attachment near the sitting bone is especially vulnerable.

Do not try to straighten the legs fully; prioritise a neutral pelvis and neutral lower back over hamstring length.

Hip Injury

Deep hip flexion, external rotation, or weight-bearing can aggravate labral tears, impingement, or bursitis.

Do not force the hip into deep external rotation; keep the foot turned out only as far as is pain-free.

Ankle Injury

Unstable or injured ankle joints can be overstressed by weight-bearing, extreme dorsiflexion, or plantar flexion.

Place a folded blanket under the ankle to cushion it, or practise a seated version of the pose.
