Explanation: FITT cycle are the factors that are used when designing or implementing a training regime.  

Frequency: This is how often we train. How often our sessions are planned (e.g. a month, week etc.)

Intensity: this is how hard you work out. The intensity level can be determined by work difficulty(Weights, cardio).  

Time: this is how long your training sessions are or length of the activities that take place during the training session.
