Buses in London - Operation. 1  Most local buses within London form a network managed by London Buses, an arm of Transport for London.
But today I had a brief chat with a personal trainer, and he told me that If I am eating 1200 calories a day and want to lose weight, I need to burn around 1700 calories A DAY, so should be in the gym 1-2 hours every day for an intense workout. Isnt that too extreme, having to spend 2 hours a day, 7 days a week just to lose 1 pound a week?
Most people overestimate the number of calories they burn with exercise and are unaware of the calories in everyday food -- particularly fast food. For example, for the average person, one hour of high impact aerobics, vigorous weight training, circuit training or playing basketball, will burn about 500 calories.
