Personal Trainer
What you'd actually do
The work is assessing clients, planning tailored programmes, running sessions, motivating people and giving advice on exercise and lifestyle. Good fitness knowledge, encouragement and the ability to adapt to each client matter, along with the business side of finding and keeping clients, since many trainers are self-employed.
Hours often include early mornings, evenings and weekends to suit clients, the work is active and on your feet, and income varies a lot - some build a strong client list and do well, others find it slow to start. Many trainers are self-employed and rent space in a gym, so building a reputation is key.
You need a recognised personal training qualification, usually gained through a college course or apprenticeship, plus first aid and insurance. An enhanced DBS check may be needed for some clients, and your results and word of mouth drive your success.
