Answer 2

Time of the day is the independent variable since at any point in time time of the day shal be moving and shall be there constantly but the intensity of the training shall rely on the time of the training, so it becomes a dependent variable, this means that its outcome relies on the time of the day but the time of the day does not rely on training intensity to change.
