Final answer:
Muscles work against a force, shorten, and move through a full range of motion during resistance exercise.
Explanation:
Muscles are working against a force during resistance exercise as they contract and create movement.
Proper technique in resistance exercise helps in muscles shortening and going through a full range of motion.
Concentric contractions occur when muscles contract and shorten against a resistance, like in the lifting phase of a bicep curl.
