Hello! I have a dilemma and I need you to help me to resolve it. I am a personal fitness trainer in a gym that people attend for working out. I instruct and train them. But I also teach them how to eat right and lose weight in order to keep in shape. So I am totally lost. What is it called in English? What are they to me? Students? Clients? Trainees? I get that they're not wards or patients. I am writing a book about losing weight and I opted for "my trainees (achieved results)" but now I am second guessing myself since I've read that it mostly applies to 'a person undergoing training for a particular job or profession'. Please help me out. Big thanks.
