Sometimes overlooked as a form of exercise, walking briskly can help you build stamina, burn excess calories and make your heart healthier.
You don't have to walk for hours. A brisk 10-minute daily walk has lots of health benefits and counts towards your recommended 150 minutes of weekly exercise.
Any shoes or trainers that are comfortable, provide adequate support and don't cause blisters will do.
If you're walking to work, you could wear your usual work clothes with a comfy pair of shoes and change shoes when you get into work.
For long walks, you may want to take some water, healthy snacks, a spare top, sunscreen and a sunhat in a small backpack.
If you start going for longer walks regularly, you may want to invest in a waterproof jacket and some specialist walking shoes for more challenging routes.
A brisk walk is about 3 miles an hour, which is faster than a stroll.
One way to tell if you're walking briskly is if you can still talk but can't sing the words to a song.
