A one-repetition maximum (1RM) is a amount of weight that can be lift exactly one time. The 1RM is a measurement of an individual’s absolute strength. Additionally, the 1RM allow an individual to calculate the percentages of their 1RM that they should lift during their training sessions.
By knowing the percentages of their 1RM that they should lift, an individual can ensure that the weights that they lift during their training session matches their training goals. Without knowing an individual’s 1RM, it is difficult to ensure that the loads that they lift during their training session are appropriate to there goals. An individual can estimate their strength using mathematical formulas, such as the Epley formula or the Brzycki formula, which requires knowledge of the number of repetitions that an individual can lift with a specific weight.
What a One-Rep Max Is and How to Test It
In order to determine a true 1RM, there are risks that an individual must avoids by following specific safety procedures. These procedures includes warming up before performing a 1RM test, increasing the weight to 90% of an individual’s estimated 1RM, allowing long rest periods of three to five minutes between set, and the lifter should perform the 1RM lift with a spotter while maintaining properly form. If an individual skips warming up or increases the amount of weight too quickly, the weight may pin them or they may get injured during the 1RM test.
The chart above includes information regarding the different percentage of 1RM an individual can lift and the variables that impact training performance. For instance, lifting at 100% of an individual’s 1RM will require them to lift the weight once and will require a high rate of perceived exertion. Additionally, lifting at 100% of an individual’s 1RM will require a rest period of five minute or more.
If an individual lifts at 85% of their 1RM, they will lift the weight five or six times. Additionally, people use lifting at 85% of 1RM to develop the ability to lift heavy weight quickly. Loads that are much heavier than 1RM are used to increase neural drive.
Conversely, lifts with lighter loads allow an individual to develop muscle size. The rate of muscle hypertrophy is best experienced in the range of 70% to 80% of an individual’s 1RM. Hypertrophy is the result of metabolic stress and mechanical tension in the muscle during training.
An individual’s body adapts to the amount of stress that is placed upon their body. Therefore, knowing the type of adaptation that is desired allows an individual to choose the appropriate percentage of their 1RM that develops the desired adaptation. Benchmarks allow an individual to compare their strength to their bodyweight.
With these comparison, an individual can determine if they are a beginner, intermediate, or elite lifter. An elite lifter will have a greater amount of strength relative to their bodyweight than an individual that is a beginner in strength training. Additionally, the rate at which an individual strengthens themselves will slow as they become more skilled with the type of strength they are demonstrating.
A beginner may be able to add 10 pounds of strength per week relative to their bodyweight compared to an elite lifter that may only be able to lift 1 or 2 pounds of additional strength each week. Because performing a 1RM test allows the body to experience fatigue, it is important for an individual to test their 1RM sparingly. Too frequent performing a 1RM test may lead to overtraining of the body.
An individual should only test their 1RM every eight to twelve week. In order to increase the safety and accuracy of the strength training process, there are a variety of tool that can be used. One of these tools is a weightlifting belt that increases an individual’s strength when bracing their body.
Additionally, lifting chalk will allow an individual to have a better grip on the strength training implement. Another tool to increase strength training accuracy is the use of rack safeties that will catch the implement if the individual should fail to complete the lift. Should an individual not use these safeties, they may slip on the implement, which can cause the individual to lose control of the implement.
In order to recover from strength training sessions, an individual should consume protein and carbohydrates to replenish their bodys energy and muscle. Additionally, an individual should take time to get enough sleep and perform light activity during the days following a 1RM test to allow their body to recover. You should of known that its better to take it easy after a heavy lift.
