Mark has been participating in a vigorous exercise routine for the past three months. However, around the start of the third month, he noticed he stopped making gains in his strength and cardiovascular endurance. Recommend two suggestions to Mark that would allow him to continue to improve his strength.

Answer:

Mark is not experiencing any gains in his strength and endurance because he's not applying the principles of fitness to his exercise routine. First, he needs to ensure he is overloading his muscles every session since his body has adapted to his current routine. Next, Mark needs to make sure his routine is progressing in duration, intensity, frequency, and type. Lastly, he needs to make sure he sets specific goals so he has a roadmap to follow.
