Do you ever get days where you struggle to make it through to lunch time, let alone the end of the day? Do you always find yourself trudging up the stairs instead of bounding up them two (or even one) at a time? Do you constantly find it an effort to get out of bed and get going in the morning, ready to face the day?

If you do, your body is probably crying out for some decent exercise. We all need it but getting it isn't always as easy as it should be. We always find excuses to do other things which usually involve a lot less effort.

Yet regular exercise gives us more stamina, which in turn makes it far easier to get through each day and still have plenty of energy left over to enjoy our time off from work.

Three of the best forms of exercise you can get can be combined with taking the kids on a day out, or simply getting outside and enjoying the fresh air and scenery - even if it means getting in the car to drive to the countryside, if you live in a town. Running, hiking and cycling are all enjoyable forms of exercise that will improve your stamina, and if you find you really enjoy one or more of them you can be really pro-active and take part in a to raise some money for a local or national charity of your choice.

These events can also result in you seeing and enjoying areas you wouldn't otherwise visit. They tend to be organised and take place in major towns and cities, so instead of riding your bike around your local area you could find yourself cycling across Tower Bridge in London, or riding through another famous city and past lots of well known landmarks.

Many people find they enjoy the camaraderie and positive feelings they get from taking part in this kind of organised event. It enables them to enjoy their favourite form of exercise, see a new area, meet new people and raise cash all at the same time.

You might also find you like the idea of taking part in a fun run, bike ride or hike in another country altogether. Just imagine strolling along the Great Wall of China, taking photos and enjoying the knowledge that you have lots of sponsorship money to collect when you get back home.

So long as you are well prepared for this kind of event, and you've taken the time to build up your stamina levels before taking part, this could even be the start of a whole new and regular activity for you to enjoy. Who would have thought that increasing your stamina could be so rewarding?
