Running is great exercise. Running is an inexpensive activity. You can run on a treadmill. You can run outdoors. You should not
RSB [31]

Answer:

The revision of the passage that best connects ideas and adds variety is - Running is inexpensive, yet you can run on a treadmill. You can run outdoors, however, you should not run on icy roads.

Explanation:

The sentences given are short and simple. But when it comes to fusing the meaning and making it sound better, linking words are used. Here, using the words "yet" and "however" all the short sentences are joined to form one sentence which sounds well and offers the correct meaning at the same time. The flow of the sentence is better. There is less amount of jarring and stopping which helps it to connect ideas and add variety to the joined sentences.

1. How can I use the Overload Principle (FITT) to improve aerobic fitness?
Arada [10]

Answer:

Explanation:

The overload principle is one of the seven big laws of fitness and training. Simply put, it says that you have to increase the intensity, duration, type, or time of a workout progressively in order to see adaptations. The adaptations are improvements in endurance, strength, or muscle size.

In other words, when a client first starts working out, from having been previously mostly sedentary, they will see some quick gains. But, as they get fitter, you will need to increase the intensity of their training to continue to see those gains. If they continue lifting the same weights for the same number of sets and reps, week after week, the body will have adjusted to the stress, there will be no more adaptations and they will plateau.
