Answer:
A) warm up before getting started.
Step-by-step explanation:
The first thing to do before doing any weight resistance training is to do some warm up before lifting any type of weight. This warm up can either be a brisk walk or light jog to stretching. The aim of doing the warm up before doing weight resistance training is to get blood flowing to every part of her body, especially the joints and muscles so as to reduce the risk of muscle tear injuries.
Sarah is already at risk of muscle tear at her shoulders because she is already exerting pressure at her chest and shoulders (depending on her grip).
