1 Rep Max

The 1 Rep Max (1RM) is the maximum amount of weight an individual can lift for one repetition of a given exercise. It is commonly used as a measure of strength and as a basis for determining appropriate training loads.

Knowing your 1RM helps you design effective strength training programs by setting weight percentages for various exercises. It ensures you're working within optimal ranges for strength, hypertrophy, or endurance goals.

Note: Estimating your 1RM can be safer than attempting a maximum lift, especially for beginners
or those without proper supervision.
