During which phase should a client inhale to properly control internal pressure while lifting?

The correct choice highlights the importance of breathing techniques in strength training. During the eccentric phase of lifting, the muscles lengthen as they control the weight being lowered, and it is a crucial time for the lifter to focus on inhaling. Inhalation helps to stabilize the core and manage intra-abdominal pressure, which is vital for protecting the spine and maintaining proper technique.

This practice of inhaling during the eccentric phase allows the lifter to engage their core properly, which plays a significant role in maintaining good form and preventing injuries. Proper breathing also aids in muscle control, contributing to a safer and more effective training session.

In contrast, inhaling before the lift starts and during the rest phase doesn't provide the same stabilization benefits during the working phase of the lift. Focusing on breathing during the concentric phase, when lifting the weight, would fail to utilize the core engagement benefits afforded by an intentional inhalation during the eccentric movement. Hence, breathing correctly during the eccentric phase is a fundamental aspect of safe and effective strength training.
