Carlos is developing an exercise program to increase his muscle strength. he has been weight training regularly for over a year. his goal is to do 15 repetitions of each exercise at 85% of his maximum strength level, with 5 minutes of rest between sets. based on what you know about the relationship between repetitions, intensity and rest on the strength-endurance continuum, what change should he make to his plan?

to reduce the repetitions

Explanation:

If Carlos wants to develop strength, he needs to use high resistance, like in this example, 85 % of his maximum strength level, but with few repetitions, in this case, that he wants to make 15, he needs to reduce this number.

In the other hand, if he wants to increase the muscular endurance, he needs to use low resistance and increase a lot the number of repetitions.

Remember the continuum is the relationship among repetitions and resistance that a person need to build muscle fitness.
