Researchers from the University of Houston have discovered that the soleus, a muscle that represents only 1% of body weight, can work by itself the'magic' of accelerating our metabolism if activated correctly. Just by doing SPU ('soleus 'pushup' or soleus push-ups) during our workday it is possible to effectively accelerate muscle metabolism for hours.
The research suggests that the effectiveness of soleus flexion in maintaining oxidative metabolism (the process by which oxygen is used to burn blood glucose or fats) is elevated.
