The soleus muscle in the calf, though only 1% of your body weight, can do big things to improve the metabolic health if activated correctly. Marc Hamilton has discovered an approach for optimal activation—he's pioneering the "soleus pushup" (SPU) which effectively elevates muscle metabolism for hours, even while one is sitting. The soleus is a posterior leg muscle that runs from just below the knee to the heel. Hamilton's research suggests the soleus pushup's ability to sustain an elevated oxidative metabolism to improve the regulation of blood glucose is more effective than any popular methods currently touted as a solution...
