The basic way to test muscular strength is with the 1-RM, which stands for which of the following?

• A. One-repetition maximum
• B. One-repetition minimum
• C. One-resisting muscle
• D. One-resting muscle

Answer: (A)

The basic idea is to measure how much weight a muscle group can lift for a single maximal effort. This is called the one-repetition maximum (1-RM). It reflects the greatest force a muscle can produce in one lift and is used to set training loads (for example, working sets at a percentage of the 1-RM). The other options don’t fit: one-repetition minimum would measure the smallest lift, which isn’t a standard strength test; one-resisting muscle and one-resting muscle aren’t recognized terms in strength testing.
