Some people often find it hard to get to a gym because of children etc, so a home personal training session would be far better for these perticular people .
Invest in a course to become an aerobics instructor, £25-£30 an hour or a personal trainer. But if you cant afford to invest then check out mystery shopper websites for your local area, you may get expenses payed for hotel stays or hair cuts, then they pay you for the report on how well the company was.
