Gastrocnemius

I he gastrocnemius is a two-headed fusiform muscle originating from t he backs of the femoral condyles and inserting on the calcaneus (heel bone) via the Achilles tendon. Its primary action is plantar flexion of the foot. The gastrocnemius also acts synergistically with the hamstrings to flex the knee during the push-off phase of walking, propelling the body forward.

Tightness in the gastrocnemius limits extension of the knee (as with tightness in the hamstrings). Facilitated stretching of the gastrocnemius is an effective method to break through limitations in forward-bending postures where the knees straighten.

Use the forward bend paschimottanasana to bring the gastrocnemius out to full length and then resist plantar flexion of the feet by pulling them towards the head with the hands. Hold this for a few moments and then extend the knees and draw the feet upward.

Gastrocnemius

This view from the floor illustrates the polyarticular nature of the gastrocnemius and how it originates from the posterior femoral condyles, crosses the knee, and inserts on the calcaneus (via the achilles tendon).

Paschimottanasana illustrates stretching the gastrocnemius by contracting the quadriceps to extend the knees. The hands dorsiflex the ankles.

Forearm & Hand

The muscles of the forearm and hand connect the upper body with the lower body in yoga. They also stabilize the body in balancing poses and inversions. Minor chakras are present in the hand that contribute to illuminating the fourth and fifth major chakras.

For ease of understanding it is useful to divide the many muscles in this region into groups identified by their function.

The major functions include flexing and extending the wrist and complex movements of the hand and fingers. For the purpose of this chapter we illustrate the flexors and extensors of this region.

The Chakra Checklist

The chakras are described as being aligned in an ascending column from the base of the back to the top of the head. New Age practices frequently associate each chakra with a particular color.
