Respuesta :
She can continue progression in lower body strength by either A) adding weight to her set of squats, or B) adding more repetitions to her set of squats. This will continue to stress her lower body muscle, causing it to grow in response to the increased work load.
Answer:
The principles of training are three: Overload, Specificity and Progression.
Overload refers to working out with a greater amount of weight, more than normal. This way, the person will develop muscle strength, because he is pushing out of his limits.
Progression refers to the increase of weight progressively, this way the improvement won't stop.
In this example, my friend should increase the weight near his limit (just near), but that amount of weight should allow him to do at least three series (he first needs to try different weights to know his limits). So, to preserve safety, I will say 3 set of 5 repetitions, with heavy weight just below his limit.
Then, I would recommend and tiny increase in each set. So, each new set must have an 10 pounds extra, this way my friend will be constantly improving. In no time, he will be breaking his limits, and reaching new weights, which also will improve the muscle strength.
