Personal Trainers are health and fitness professionals who are hired for private instruction. Generally thought to be a commodity afforded only to the rich and famous, personal trainers are now widely available for a variety of people with a variety of goals (and with a variety of budgets). Personal Trainers will help their client develop and maintain exquisite physical condition by designing a specialised exercise regimen for said client.

The emphasis on personal training should come from the Personal Trainer's understanding of what works best for their client. It is not just about pushing someone hard, but more about working out at an effective level to achieve their goals. Many people need only one session to get them on the right track, ensure their program is balanced, and answer their questions.

There are many Personal Trainers who offer their clients a range of services from exercise testing to postural exercises to helping with habitual behaviour change.

Personal trainers guide and motivate clients to reach their peak fitness potential. They assess clients' fitness needs of clients and develop plans based on them. Personal trainers provide personal training, present classes and instruct on proper nutrition.

Personal trainers must have a strong understanding of the functions and vital processes of the human body so they can effectively design and deliver personal nutrition and physical fitness training programs.

It is critical to be knowledgeable in health promotion at every stage of growth and development to meet the needs of various clients.

A good personal trainer must be energetic and motivating, always encouraging their clients to reach maximum performance.
