Biking is one of the most effective - and not to mention, enjoyable - workouts out there. Others may find this intimidating. But it is not necessary to be thin for one to cycle. Yes, a lighter body helps a lot if you want speed, but it is not a requirement for you to enjoy it.
When you are confronted with anxiety and doubts, fight the urge to make excuses and back out. Here are a few tips helpful tips:
The Right Perspective: Being unfit is not really something to be very scared about. You don't have to be in all that Lycra clothing to start biking. The extra pounds won't stop you from getting on the road. You are your own boss and you can by all means go at your own pace. Starting slow is best. Work at a speed that's comfortable to you. You don't have to do 50 kilometres right away. You can go around the neighborhood once or twice. Whatever the speed and distance, every ride counts. With regular riding, you will improve over time and you will be able to deal with self-doubt by cycling farther and longer.
The Right Gear: Make sure that you are comfortable on your bike. If it hurts to ride it, then you should have it altered to fit your body well. Most gear are in smaller sizes so go to your local bike shop for a bike fitting, you may just need a new saddle or adjust the height. Also, the bike should fit the road you'll be biking on. Hilly roads will require a different bike compared to flat and smooth roads. Ask your bike shop and don't be afraid to try the different types before deciding.
The Right Clothing: You will also need to consider the correct clothing. Longer rides will require padding for the inner thighs for you to remain comfortable. You'll need cycling gloves which will help you get the perfect grip on the bars, and of course, a helmet. You'll find stores that carry a wide range of sizes but if you cannot find anything, just be creative, improvise, and wear what you find comfortable.
If you find that the store personnel are not being courteous or accommodating, you can always go to another shop. Ignoring naysayers is the best way to go. It's a challenge but try not let them get to you. Do not be intimidated by cyclists who judge people for your weight. Remind yourself that you have every right to bike on the same road as them.
