Step-by-step explanation:
Every time you finish your target and complete the task given by your coach, you have to make an entry in the fitness log given.
For the coach to know that you have done the task for the day, you have to get a signature from the coach to show him the evidence that the task given has been completed.
This is the first thing that an individual should do after making an entry in the fitness log.
After that he can plan out the next level work out for the next day and inform his coach of the same.
