New trainees should ____ through the sticking point and _____ during the less strenuous portion of the lifts.

The correct choice emphasizes the importance of proper breathing technique during resistance training. New trainees should exhale through the sticking point, which is the most challenging part of the lift where the weight might feel heaviest. Exhaling helps to stabilize the core and maintain intra-abdominal pressure, allowing for better force generation and reducing the risk of injury.

During the less strenuous portion of the lifts, inhaling is advisable because it helps to increase oxygen intake and replenish energy for the upcoming exertion. Proper inhalation between tougher segments of the lift supports sustained performance, as it prepares the body for the next effort.

These breathing techniques align with the principles of effective lifting, where maintaining proper oxygen flow and body mechanics is crucial for safety and performance outcomes.
