CALF RAISES: CHANGE THE EMPHASIS
Straighter knees allow more gastrocnemius (“gastroc”) contribution. Seated, bent-knee raises are relatively more soleus-focused. Both muscles still work.
Why? The gastroc crosses the knee and ankle. Bending the knee shortens it and generally reduces its contribution; the soleus does not cross the knee. That is a change in relative emphasis—not soleus isolation, a promise of higher soleus activation in every situation, or evidence of greater soleus growth.
Keep the front of your feet down, raise and lower your heels slowly, and stop if painful or unsteady. Use a stable support for standing raises and a stable seat for the seated version. The unloaded illustrations explain positions, not a matched-load research test.
