Fitness is an exact science, so for maximum benefit it is advisable to hire an expert to work out the perfect exercise programme for your needs
Physical fitness training is a science but there is no fixed equation for everyone, so getting a personal trainer can help in many ways.
Some people use a personal trainer because they have a goal, such as finishing a marathon, participating in the Oxfam Trailwalker or losing fat.
Freelance personal fitness trainer Alex Hose said a personal trainer could help assess people's body condition and design special courses for them to reach their goals with their professional knowledge.
'You can go into a gym and pick up a weight, but if you don't know how to use it properly, you might hurt yourself. A lot of people don't understand that when they are walking or running, their feet go out, or their knees come in, they don't realise it needs correction.
'Everyone in the gym has their own opinions. You can easily get lost in 100 different suggestions from 100 people. Which one should you follow?'
Mr Hose said it was a good idea to talk to a professional with a good understanding of the industry.
