‘Special’ Muscle Can Promote Glucose and Fat Burning to Fuel Metabolism for Hours While Sitting - Neuroscience News
The pioneering "soleus pushup" effectively elevates muscle metabolism for hours, even when sitting.

Pretty fascinating article!
"The soleus’ lower-than-normal reliance on glycogen helps it work for hours effortlessly without fatiguing during this type of muscle activity, because there is a definite limit to muscular endurance caused by glycogen depletion,” he added. “As far as we know, this is the first concerted effort to develop a specialized type of contractile activity centered around optimizing human metabolic processes.”
When the SPU was tested, the whole-body effects on blood chemistry included a 52% improvement in the excursion of blood glucose (sugar) and 60% less insulin requirement over three hours after ingesting a glucose drink.
The new approach of keeping the soleus muscle metabolism humming is also effective at doubling the normal rate of fat metabolism in the fasting period between meals, reducing the levels of fat in the blood (VLDL triglyceride).
So, how do you perform a soleus pushup? In brief, while seated with feet flat on the floor and muscles relaxed, the heel rises while the front of the foot stays put. When the heel gets to the top of its range of motion, the foot is passively released to come back down. The aim is to simultaneously shorten the calf muscle while the soleus is naturally activated by its motor neurons.
While the SPU movement might look like walking (though it is performed while seated) it is the exact opposite, according to the researchers. When walking, the body is designed to minimize the amount of energy used, because of how the soleus moves. Hamilton’s method flips that upside down and makes the soleus use as much energy as possible for a long duration. “The soleus pushup looks simple from the outside, but sometimes what we see with our naked eye isn’t the whole story. It’s a very specific movement that right now requires wearable technology and experience to optimize the health benefits,” said Hamilton.

It's annoying they dont explain it,, but you can see what the person is doing.. I think I was able to reproduce it..
All of the 600 muscles combined normally contribute only about 15% of the whole-body oxidative metabolism in the three hours after ingesting carbohydrate. Despite the fact that the soleus is only 1% the body weight, it is capable of raising its metabolic rate during SPU contractions to easily double, even sometimes triple, the whole-body carbohydrate oxidation.
