One-rep max (1RM) calculations help determine the heaviest weight you can lift for a single repetition of any exercise. This information is crucial for structuring effective strength training programs.

Testing Your One-Rep Max

For most accurate results:

• Use lower rep ranges (1-5 reps) for better estimation accuracy
• Maintain proper form throughout the movement
• Stop if form deteriorates or range of motion decreases
• Calculate separate 1RMs for different exercises
• Always prioritize safety over numbers

Training Percentages by Goal

Speed and Power:

• 50-60% of 1RM
• 3-5 reps per set

Muscle Growth (Hypertrophy):

• 70-80% of 1RM
• 8-12 reps per set

Strength:

• 85-95% of 1RM
• 3-5 reps per set

Essential Equipment for Heavy Lifting:

• Lifting belt for core support and back protection
• Wrist wraps/elbow sleeves for pressing stability
• Wrist straps for improved grip on heavy pulls
• Knee sleeves for squat support

Advanced Training Strategies

Recent research suggests alternating between:

• 70% 1RM: 10-12 reps (4-8 week blocks)
• 90% 1RM: 3-5 reps (4-8 week blocks)

Both approaches can lead to similar muscle gains when properly implemented.

Important Considerations:

• Rep maxes vary daily based on sleep, recovery, and other factors
• Larger muscle groups (like legs) can typically handle more reps at given percentages
• Adjust weights as needed based on performance and recovery
• Different exercises require separate 1RM calculations
• Track progress using dedicated apps or spreadsheets

Remember to use these percentages as guidelines rather than strict rules, and always prioritize proper form and safety during training.
