Question

which phase when lifting weights is the eccentric phase?*the \lowering\ phase of an exercise, where the muscle lengthens under tensionthe \lifting\ phase of an exercise, where the muscle contractsa \hold\ phase in an exercise where the muscle is held under tension without changing length

Explanation:

In weight - lifting, the eccentric phase is characterized by the muscle lengthening while under tension. This occurs during the lowering phase of an exercise. The "lifting" phase is the concentric phase (muscle shortens as it contracts), and the "hold" phase is the isometric phase (muscle length remains unchanged).

Answer:

The "lowering" phase of an exercise, where the muscle lengthens under tension.
