Your calf isn’t just one muscle.
The gastrocnemius is your explosive power muscle helping with sprinting, jumping and pushing off the ground.
The soleus sits deeper and is built for endurance working hard during walking, running and standing.
Another key player is tibialis posterior, which helps support the foot arch and stabilise the foot during movement.
Strong lower legs = better power, shock absorption and foot stability.
