Observation Proposal

I am going to be observing a fitness trainer at the gym i work out at. I am going to see how he interacts during a workout session. I am going to be noticing how he talks to them and what he does with the person he is training. I will see if there are any differences from him training a male from a female. I am going to be noticing how the atmosphere is involved with the training too. I will possibly interview him and see why he does this and what are his feelings about it.
