Lunges train ankle control and the calves contribute during the step and return, though direct calf raises provide a clearer hypertrophy stimulus.
Yes. Lunges can build the quadriceps when the lead knee moves through a useful range and load, volume and effort progress over time.
They can build bracing endurance if the trunk is held deliberately, but the wall removes much of the balance demand found in unsupported squats.
The calves contribute to foot and ankle stability, but wall sits do not include the repeated plantar flexion needed for a strong calf-growth stimulus.
They involve the hamstrings isometrically, but the growth stimulus is usually small because the exercise is dominated by knee-extension demand.
Yes, mainly for isometric strength and local endurance. They can contribute to quad growth if progressively overloaded, but dynamic training covers more joint angles.
Only to a limited degree. The glutes help hold the position, but ordinary wall sits usually provide less hip-extension loading than dynamic squats or hinges.
Yes, mainly through anti-rotation and bracing. Reverse lunges challenge trunk control while the base of support changes, especially with asymmetrical loading.
The calves stabilise the planted foot and contribute to the return, but reverse lunges are supplementary rather than primary calf training.
