If you plan on going for a run – but you’re struggling to get in the mood for it – you’ll end up running a lot more slowly. That’s according to sports psychology professor Dr. Chris Englert. The reason? Because you end up using all your willpower to force yourself to put on your shoes, and get out the door. Which means, you won’t have as much willpower left to keep going when you start to feel tired. So, here’s how to restore your drive to exercise: Sit quietly and focus on your breathing for 5 minutes. Your brain will feel calmer – and you’ll be much more motivated to have a good workout. It sounds simple, but it works.
