15rm是什麼意思

"15RM" is often used in the context of weightlifting and fitness to mean "15-rep max." This refers to the maximum weight that an individual can lift for 15 repetitions. It is a way to measure strength and endurance, as it combines the ability to lift a heavy weight with the ability to perform multiple repetitions.

In some cases, "RM" may also be used to mean "repetition maximum," which is a more general term that can refer to the maximum number of repetitions that can be performed with a certain weight. For example, "1RM" would mean the maximum weight that can be lifted for one repetition, while "5RM" would mean the maximum weight that can be lifted for five repetitions, and so on.
