12rm是什麼意思

"12RM" is a term commonly used in weightlifting and strength training to indicate the maximum amount of weight an individual can lift for 12 repetitions. The "RM" stands for "repetition maximum." So, if you see a weightlifting program or workout that includes 12RM, it means you should perform an exercise with a weight that you can lift exactly 12 times before reaching muscular fatigue.

Training with 12RM can help improve muscular endurance and strength, as well as increase the size of the muscles over time due to the metabolic stress placed on the muscles during the workout. It's important to use proper form and technique when lifting at this intensity to avoid injury.
