Step-by-step explanation:
The most common complaint made by clients against their personal trainer is poor communication.
Personal trainers need to effectively communicate with their clients to understand their goals, provide proper guidance, and address any concerns or questions. Poor communication can lead to a lack of progress, confusion, and frustration for clients.
For example, if a personal trainer fails to clearly explain the proper form and technique for an exercise, the client may not perform it correctly and risk injury. Additionally, a personal trainer who doesn't listen to their client's feedback or fails to check in regularly can create a sense of disconnect and dissatisfaction. So, the correct answer is option b.
