Nearly everyone I know has some sort of regular exercise routine going with either running or the gym etc. I’d like to be that person but I’m wondering if I’m too old now at 50 to start and have I seriously left it too late? I worry about my health though I’m not overweight, my BMI is 23.5. I walk to and from work everyday (2 miles) but apart from that I don’t do any exercise to exert myself. I keep reading that you should exercise to the point of being out of breath! Would it be dangerous for me to suddenly start now?
