The easiest way to avoid a £50 fine –– or the hassle of nipping outside for a crafty smoke –– is to kick the habit, which health chiefs say is the single most beneficial thing a smoker can do for their health.

The ban came into force across England on Sunday, and director of Sport Nottinghamshire Simon Starr hopes it will prove the incentive smokers need to cut down the amount they smoke or give up completely.

"You'll feel so much healthier," he said. "We're encouraging everyone to use this as a spur to get fitter and more active and if you are able to cut down or give up, then sport and physical activity can be a great alternative.

"The Shape Up Notts! campaign is there to support you if you choose to start getting active. The campaign is run through the website and it is completely free to join.

"Once you have registered you can access a whole host of motivational services, including an online exercise diary, information about local sporting events and clubs and loads of advice regarding health and fitness.

"The smoking ban is the perfect opportunity to put down your cigarette packet and pick up a pair of trainers.

"The money you'll save could be used to pay for gym membership or a bike –– something really positive that could make a huge difference in your life."

And for those concerned that giving up smoking will increase your appetite, exercise is the perfect solution. Building up to three 30-minute sessions a week will enable you to eat more as you are burning off more calories.

More than 1,500 people have already signed up to the website and the online forum is full of members who are keen to help one another stay motivated — meaning there is a great deal of support to help you beat the nicotine cravings.
