Celebrity trainers and buff social media stars use terms such as “shred”, “burn” and “melt” to describe bodies responding to resistance training and cardiovascular exercise with rapid physical transformation. 
In the kitchen, shredding a carrot takes just a few minutes and results in destruction of a solid into small, manageable parts. Burning involves heat and occasionally pain, and can occur in just seconds (especially if you turn your back). Solid fats melt into liquids that can be drained away.
But do these terms actually describe what’s going on when we exercise? A simple analysis of how our body uses, stores and mobilises energy says no, they don’t.
Tags like #shred, #timetogrind and #workhard suggest your new body is just around the corner. be_more_athletics/Instagram
