Your weekly dose of evidence
|
|
The weekend can be a great time to fit in some exercise. Or, a perfect time to relax and not to exercise, if you see things like I do. But if you’re donning your activewear and planning a run or a ride this weekend, you might be interested to know exercising at your maximal heart rate isn’t the best way to go. Angela Spence explains that pushing yourself to the highest possible intensity isn’t sustainable – and importantly, isn’t necessary to
to gain health benefits.
Meanwhile, a study published this week gives us an insight into exercise addiction. A healthy relationship with physical activity can become an addiction if time exercising starts costing other aspects of your life, or if missing a session causes you distress. Katinka van de Ven, Ornella Corazza and their team found more than one in ten gym goers are at risk of exercise addiction.
