Estimate your deadlift one-repetition maximum (1RM) using our calculator. Input the weight you lifted and the repetitions you completed during a recent set. This tool provides an estimated 1RM, representing the heaviest weight you can lift for a single, full repetition. Use this figure to gauge your current strength level and track progress over time.

Your estimated 1RM is a benchmark. It helps you understand your strength potential and informs your training intensity. The calculator also provides percentages of your 1RM, useful for programming training cycles. For example, lifting at 70-80% of your 1RM is common for hypertrophy, while 85%+ is typical for strength development.

To effectively use your 1RM, integrate it into your training plan. If your estimated 1RM is 200kg, then a training session requiring 3 sets of 5 reps at 75% would mean lifting 150kg. Regularly re-test your 1RM (perhaps every 8-12 weeks) to adjust your training weights and continue making progress. Remember, this is an estimate; actual 1RM can vary.

// Frequently Asked

Questions, answered.

How accurate is this 1RM calculator?

Our calculator uses established formulas to provide a close estimate of your 1RM. While highly reliable, it's an estimation. Your actual 1RM might vary slightly due to factors like fatigue, technique, and motivation on the day of testing.

Why is knowing my deadlift 1RM important?

Knowing your 1RM helps you program your training effectively. It allows you to select appropriate weights for different rep ranges and training goals, ensuring you train at the right intensity for strength, hypertrophy, or endurance.

How often should I re-test my 1RM?

Re-testing your 1RM every 8-12 weeks is generally recommended. This allows sufficient time for strength gains to occur and helps you adjust your training weights to reflect your improved capabilities, ensuring continued progress.

Can I use this calculator for other lifts?

While designed for deadlifts, this type of 1RM calculator can be broadly applied to other compound lifts like squats and bench presses. Always ensure proper form and safety when testing or estimating your 1RM for any exercise.
