Often making the time for regular exercise can be hard. Long commutes might leave no time in the morning and family commitments may not allow precious free time being spent at a gym.
The answer could lie in the work place and it is quite likely that your colleagues might be in a similar boat.
Why not join up and have a good walk after eating your lunch. This can be a very sociable arrangement and also it provides support, ensuring it happens every day.
If possible, see if you can leave the car at home and walk to work. Perhaps instead of hoping on a bus you could cycle instead.
For those who live too far away, you could park, as far away as possible from your office, forcing you to walk a bit more. Public transport users could even get off one stop earlier and walk the rest of the way.
During office hours make any excuse to get up and walk, avoid sending e-mails or picking up the telephone, go and actually see the person across the room. Turn a coffee break into five minute fitness routine. There are many products in the market that can be either portable or just designed for this type of use.
In terms of equipment, there is a large array of fitness kits including things like treadmill desks. Sitting on an exercise ball instead of a chair could work, although you would have to be careful about your back posture.
You could even share the cost of a particular item with work mates or maybe your employer might want to invest on keeping his staff in better condition.
