3D anatomy model of Standing Forward Fold: working muscles in red, stretching in blue, stabilizing in yellow

Opening the 3D model…

Fold deeply from the hips to lengthen the back of the body: hamstrings, gastrocnemius, and erector spinae. Contracting the quadriceps helps the hamstrings release (reciprocal inhibition).

Muscles in this pose

Working (contracting): Quadriceps, Iliopsoas

Stretching: Hamstrings, Gastrocnemius, Gluteus maximus, Erector spinae, Multifidus, Quadratus lumborum, Trapezius

Stabilizing: Soleus

Why these muscles work or stretch

Quadriceps · Working (contracting): Contracts so the hamstrings can release (reciprocal inhibition)
Iliopsoas · Working (contracting): Draws the torso deeper into the hip fold
Trapezius · Stretching: Upper fibers lengthen as the head hangs

Practice cues

Hinge at the hips; don't round your upper back
Engage your quadriceps to help your hamstrings release
Relax your neck and let your head hang

Benefits

Cautions / contraindications
