Answer:
Evaluate and adjust her choice of activities, frequency, duration, and intensity.
Step-by-step explanation:
When people is in this position, the training program doesn't give results, they take two actions: leave it or increase it. But both actions are wrong, because giving up Laura never will improve, and increasing intensity she could even harm her body. So, the best option is to evaluate each area that she included in the training program.
In addition, Laura can adjust every exercise step by step, first she can look for other activity, maybe the new exercise will give her a little more intensity. She can even only change the frequency like working out two times per day with low intensity exercises.
Basically, Laura needs to change slowly her training program, until find the problem, the worst action she can do it's to change drastically.
