1. Get more sleep
You’re less likely to hit your maximum intensity if you feel like crawling into a hole. Melanie McGrice, from the Dietitians Association of Australia, says tired people are less likely work out.
“It makes it really easy to think of an excuse not to go to the gym.” There’s also a good physiological reason to get enough kip. “We know that lack of sleep decreases the production of leptin, which is a hormone that helps us to know when to stop eating, and we know that it increases the production off ghrelin, which is a hormone which increases our appetite,” McGrice warns.
