Can't find the time or motivation to go to the gym a couple of times a week? Tell that to Mac Robson.
Five days a week, for the past 30 years, the 73-year-old has been going to YMCA Auckland City Fitness, and he can't speak highly enough of it.
"There's not just one benefit," he says. "It's not just your level of fitness, it's not just the mental stimulation, it's not just the group of friends, or the routine. It's all of those things rolled into one."
Robson wakes at 4.45am so he can beat the traffic into town and start his day with a workout.
"You feel good about yourself, you get your body up and working and by the time you get to work you are fizzing. It's something I don't think people who haven't experienced it understand, but it's a huge feeling of well-being."
