If you're working from home, are recovering from a leg injury that doesn't yet permit you to put weight on your feet or are otherwise immobilized but still need to get a decent workout in that will elevate your metabolic rate then this one is for you. Seated Calves also known as calf push-ups activate the soleus muscle that runs at the back of your calf from your Achilles tendon to your knee. Research has shown that despite the fact that the soleus is only one per cent the body's weight, it is capable of raising its metabolic rate during contractions to easily double, even sometimes triple, the whole-body carbohydrate oxidation. The result is you get a pretty decent energy burn without having to leave your seat.
