What two muscles are used to climb stairs, stand up, and walk?

The quads extend your knees when your legs straighten. The hamstrings, sartorius and gastrocnemius flex your knees. The gastrocnemius and soleus assist during plantar flexion, when you push up from a step, while the tibialis anterior is primarily responsible for dorsiflexion when your foot lands on a step.
