Ideas for scene 3

Scene 3 is set in the gym. I am going to have to get permission to film at my local gym. The idea of this sequence is to capture the effort the main character and for the audience to get an insight to his strict training regime. I will film in the evening, so I will have to set up the camera to deal with the indoor lighting. In the sequence I aim to use a lot of low angle shots, close ups and possibly high angle shots. I may try to get a more documentary style of filming and abandon the tripod, to get a more realistic feel to the filming.
