你的身边有热爱运动健身的人吗？锻炼身体固然对健康有益，但有些人却过分地沉迷于此。

Do you like to keep fit? We're always told that regular exercise is good for our body and mind. More and more people are taking up activities that improve their fitness. But is there a risk some of us might get obsessedand overdoit?

Well, for some people, fitness has become an obsessionas they aim for perfection. And fitness trackers and apps can add to this addictionand mental health complications. According to a BBC Worklife article: "Research from scientists at University College London in 2017 found that higher Instagram usage was associated with increased likelihood of developing orthorexia, especially among followersof the 'healthy eating' influencers."

Too much exercise can also take its tollon someone's physical health as well. Symptoms of over-exercising include injuries such as stress fractures, tendinitis and a low immune system. So how much exercise is too much? Research by the Journal of the American College of Cardiology found the ideal pace to jog was about eight kilometres per hour – and that it was best to jog no more than three times a week or for 2.5 hours in total, showing that moderate jogging is possibly more beneficial than being inactive or undertakingstrenuousjogging.

If you're more of a couch potato than a sprinter¹⁰, this might sound like good news. But for amateur athletes who can't help but push their bodies to the limit, the advice from Martin Turner, a sports and exercise psychologist, is, "it's all about letting go, not being obsessed, learning not to control everything, saying, 'You don't need to be perfect.'"
