What is an 8 Rep Max (8RM)?
Your 8 rep max (8RM) is the maximum weight you can lift for exactly 8 repetitions with proper deadlift form. This rep range is ideal for hypertrophy (muscle building) training and is commonly used in bodybuilding-style programs.
Perfect for Muscle Building
The 8-12 rep range is considered optimal for hypertrophy. At 8 reps, you're still lifting heavy enough to stimulate strength gains while getting enough volume for muscle growth.
