So I ' m finding week3 quite tough so I plan to repeat this week again . I was able to get through day 1 without too much trouble but I struggled to complete the last rep in both days 2 and 3 . Although I ' m disappointed to have hit a slight wall I feel I 'll benefit in the long run . For me this is more the ability to factor something like this into my weekly training schedule than being able to push out 100 consecutive push - ups .
According to the above context, choose the best option to answer the following question.
Question: What may be the reason they have hit a wall ?
Options:
- They did n't stop before they got to the wall .
 - None of the above choices .
 - They have been eating too much junk food .
 - They do n't have enough energy .


They do n't have enough energy .
