b. perform an aerobic warm - up activity before lifting
c. use your entire body to lift the weight
d. always have a spotter

Explanation:

Warming - up is crucial before weight - lifting to prevent injuries and prepare the body. Aerobic warm - up increases blood flow and loosens muscles. Preselcting exercises is important but not as essential as warming up. Using the entire body isn't always correct as some exercises target specific muscles. Having a spotter isn't always possible or necessary for light weights. Holding breath can be dangerous. Performing through the full range of motion is good but warming up comes first.

b. perform an aerobic warm - up activity before lifting
