I've always said that you don't have to work out at the gym all day in order to control your weight. All you need is a minimum of 30 minutes a day filled with consistent, moderate movement or activity. And it doesn't have to be hard. Consistency is the key. 60 minutes is the ultimate goal, and doing it daily is the way.
Start by walking every morning for just 10 minutes. Then increase it to 15 two weeks later, then 20 in the next two weeks. Then 25, and at the end of about two months – make it a thirty minute walk. This is the minimum you need to do – and do it every day.
You can build up to 60 minutes a day, by varying your activities with dancing, tai boxing, bicycling, tennis, gardening, swimming, yoga, basketball – whatever you like, that's fun for you.
