Jumping on a bike, inside or out, increases your cardiovascular fitness and burns calories whilst being kind to the environment, and can also be a favourable means of transport. Nowadays, many people take to a bike to get into shape as it's easier on the joints and bones than many other activities and contrary to popular belief, it makes use of a range of muscles, not only in the legs, but also including the gluteus maximus, biceps and triceps. This makes it a great option for those who want to avoid high-impact, more strenuous exercises but still want to boost health and reduce stress. Cycling is the perfect way to build stamina whilst enhancing strength and muscle tone and according to the British Medical Association, cycling just 20 miles a week can reduce the risk of coronary heart disease by a considerable 50%. So, when choosing between indoor vs. outdoor cycling, how do you decide which style of cycling would suit you best?
