Respuesta :
Intensity- he isn’t changing the times per week or the total time lifting, just the weight.
Answer:
intensity
Explanation:
Training intensity is one of the most important variables for the constant control and maintenance of training results.
Depending on the type of physical activity, intensity can be measured in different ways, for example:
- in bodybuilding, with the weight lifted in each exercise,
- In running, we can choose heart rate as one of the forms of control.
As stated above, the intensity of physical training may be related to the increase or decrease in weight carried during training. From this we can conclude that if Matt decides to change the amount of weight he raises twice a week from 30 to 45 pounds, he is working on the intensity of his training.
