If you are in your mid-forties or older and want to add some years to your life, than you may want to think about upping the ante when it comes to your workout. A new Australian study claims that high-intensity exercise – one that makes you sweaty and winded – may reduce your chances of dying early by up to 13 percent. According to the Mayo Clinic, vigorous exercise implies your breathing is deep and rapid, you develop a sweat after a few minutes of activity and you can’t say more than a few words without pausing for breath. You don’t want to overexert yourself, which can lead to serious health risks, so make sure to modify if you are experiencing any shortness of breath or pain or if your heart rate exceeds your target zone.
