What is a 3 Rep Max (3RM)?
Your 3 rep max (3RM) is the maximum weight you can lift for exactly 3 repetitions with proper deadlift form. This rep range is commonly used in strength training programs and is considered very accurate for estimating your true 1RM (one rep max).
Why Calculate 3RM?
3RM testing is safer than 1RM testing while still being very accurate. It's commonly used in programs like Starting Strength, 5/3/1, and other popular strength training methodologies.
