We all hold the secret to getting fit, according to researchers from the University of Exeter. The research team has shown that we each have a built-in ability to judge how hard our bodies are working, often with remarkable precision.A series of studies over the last two years, culminating in three academic papers in the past two months, has shown a consistently close correlation between actual and perceived exertion in people of all levels of fitness. The team has found that an individual’s own sense of how hard he or she is working corresponds exactly with actual level of exertion, measured by heart-rate and oxygen uptake.
