Your Performance
Power Test
Input a recent feat of strength (between 2 and 10 reps) to safely simulate your absolute performance.
What is the 1RM (One Rep Max)?
The 1RM, or One Repetition Maximum, corresponds to the absolute maximum load you can lift for a single, solitary repetition on a given exercise, with impeccable technique. It is the ultimate marker of pure strength used in Powerlifting and Weightlifting.
Why ESTIMATE rather than TEST?
Testing your true 1RM under a bar is extremely taxing on your central nervous system and connective tissue. In case of failure (especially on the bench press or squat), the risk of severe injury is immense without competent spotters. A reliable predictive formula (like Brzycki or Epley which we use) secures your training.
How to use the percentages?
Knowing your 1RM allows you to calibrate all your future resistance or strength sessions. If a program indicates '3 sets of 5 reps at 80% of your 1RM', you no longer have to guess. You can mathematically set up hypertrophy blocks (65-80%) or strength blocks (85-95%).
Am I strong for my weight? (Strength Standards)
Lifting 225 lbs on the bench press doesn't mean the same thing if you weigh 150 lbs or 260 lbs. This is why strength is always judged relative to bodyweight. Here are the thresholds to aim for to validate a level (Male Standards):
- Novice (1 year lifting)
Bench: 0.8x BW | Squat: 1.1x BW | Deadlift: 1.2x BW
- Intermediate (3 years strict lifting)
Bench: 1.2x BW | Squat: 1.5x BW | Deadlift: 1.7x BW
- Elite (Competitive Powerlifter)
Bench: 2.0x BW | Squat: 2.5x BW | Deadlift: 2.7x BW
Next Step: Program your workouts
You know your 1RM and your strength ratios. Now you must inject these numbers into a structured hypertrophy block (PPL, Upper-Lower) to shatter your records!

How much rest between heavy sets?
If you are programming sets in the 85-95% of your 1RM zone (1 to 4 repetitions), your central nervous system will need 3 to 5 solid minutes to fully recharge its local ATP (Adenosine Triphosphate). Do not cut your rest short!
Can I use a 15-rep set to calculate my 1RM?
Mathematical formulas become exponentially inaccurate past 10 repetitions. If you indicate lifting a weight for 15 reps, lactic acid and muscular endurance physiology will completely distort the calculation. For a reliable estimate, use a validated performance between 2 and 8 repetitions.
