For resistance training, how is intensity expressed?

Intensity in resistance training is primarily expressed as a percentage of an individual's one-repetition maximum (1RM). The 1RM represents the maximum weight that an individual can lift for one complete repetition of a given exercise. By using a percentage of 1RM, trainers can effectively gauge the difficulty level of the exercise relative to the individual’s strength capacity. For instance, lifting at 70% of 1RM is generally considered a moderate intensity, allowing for a certain number of repetitions to be performed, which is beneficial for building strength and muscular endurance.

This method of expressing intensity helps trainers design programs tailored to specific fitness goals, such as strength, hypertrophy, or endurance. Understanding the relationship between the weight lifted and the individual's maximum lifting capacity is vital for optimizing training results while managing the risk of injury.
