Final answer:
Lifting with high repetitions and low weight is commonly used to tone and increase muscular endurance, not build muscular size.
Step-by-step explanation:
False. Lifting with high repetitions and low weight is commonly used to tone and increase muscular endurance, rather than build muscular size. To build muscular size, the intensity of the exercise must be increased by using increasingly heavier weights. This makes it more difficult for muscles to move the load and causes the muscle to adapt and grow in size.
