Our calculator uses a three-step process grounded in exercise science to determine where your strength level falls within the population of trained lifters. Here is how it works.
Estimate Your 1RM
We use the Epley formula, one of the most widely validated equations in strength research, to convert any set of weight and reps into your estimated one-rep max.
1RM = weight x (1 + reps / 30)Normalize for Body Weight
Absolute strength varies enormously with body size. We divide your 1RM by your body weight to produce a strength-to-weight ratio, allowing fair comparison across all weight classes.
Ratio = 1RM / bodyweightMap to a Rank
Your ratio is compared against gender-specific and exercise-specific percentile thresholds derived from population data to place you into one of GROOVE's 12 ranks, from Bronze III to Champion.
Ratio → Percentile → RankUnderstanding Strength Standards
The table below shows the approximate 1RM-to-bodyweight ratios required for each rank across the three major compound lifts for male lifters. Female thresholds are roughly 60-65% of male values. These standards are based on aggregated data from strength research and competitive lifting populations.
| Rank | Bench Press | Squat | Deadlift | Percentile |
|---|---|---|---|---|
Bronze III |
< 0.50x | < 0.68x | < 0.75x | Bottom 10% |
Bronze II |
0.50 – 0.65x | 0.68 – 0.88x | 0.75 – 0.98x | 10 – 20% |
Bronze I |
0.65 – 0.80x | 0.88 – 1.08x | 0.98 – 1.20x | 20 – 35% |
Silver III |
0.80 – 0.95x | 1.08 – 1.28x | 1.20 – 1.43x | 35 – 45% |
Silver II |
0.95 – 1.10x | 1.28 – 1.49x | 1.43 – 1.65x | 45 – 55% |
Silver I |
1.10 – 1.25x | 1.49 – 1.69x | 1.65 – 1.88x | 55 – 65% |
Gold III |
1.25 – 1.40x | 1.69 – 1.89x | 1.88 – 2.10x | 65 – 75% |
Gold II |
1.40 – 1.55x | 1.89 – 2.09x | 2.10 – 2.33x | 75 – 82% |
Gold I |
1.55 – 1.70x | 2.09 – 2.30x | 2.33 – 2.55x | 82 – 90% |
Platinum |
1.70 – 1.90x | 2.30 – 2.57x | 2.55 – 2.85x | 90 – 95% |
Diamond |
1.90 – 2.10x | 2.57 – 2.84x | 2.85 – 3.15x | 95 – 99% |
Champion |
> 2.10x | > 2.84x | > 3.15x | Top 1% |
Ratios shown are for male lifters. Female thresholds are approximately 60-65% of male values. "x" refers to multiples of body weight. For example, 1.25x at 80 kg means a 100 kg one-rep max.
What Your Rank Means
Each of GROOVE's 12 tiers represents a distinct stage in a lifter's journey. Whether you are just getting started or chasing elite status, your rank tells a story about where you are and what comes next.
Bronze III – I
You are building a foundation. Most lifters start here in their first few months of training. Focus on learning proper form and building consistency. Progress at this stage is fast.
Silver III – I
Solid intermediate territory. You have put in 6-18 months of consistent training and your numbers show it. You are stronger than the average gym-goer and building real competence.
Gold III – I
Advanced lifter. You are in the top quarter of trained lifters. Reaching Gold takes years of dedicated work. Progress slows, but every PR hits different at this level.
Platinum
Elite territory. You are stronger than 90% of people who train regularly. Getting here requires smart programming, nutrition, and years of commitment. Respect.
Diamond
Exceptional. Top 5% of trained lifters. At this level, you likely have competitive potential in strength sports. Every fractional gain is earned through meticulous effort.
Champion
The pinnacle. Top 1% of all lifters. Champion rank represents the boundary of human strength potential for your weight class. This is where legends live.
Frequently Asked Questions
The Epley formula is most accurate for sets of 1-10 reps, with an error margin of about 5%. For higher rep ranges (10+), accuracy decreases. For the most precise result, use a recent set of 3-6 reps at a challenging weight. If you know your actual 1RM, enter it with 1 rep for perfect accuracy.
Yes. Our thresholds are derived from aggregated data including competitive powerlifting results, peer-reviewed research on trained populations, and large-scale gym tracking data. Standards are continuously refined as more data becomes available through the GROOVE app.
Each exercise has its own strength curve and muscle group involvement, which means population distributions are different. Most lifters can deadlift more than they squat, and squat more than they bench. The thresholds account for these differences so your rank reflects your strength relative to other lifters on that specific movement.
We divide your 1RM by your body weight to produce a strength ratio. This means a 70 kg lifter benching 100 kg (ratio: 1.43x) ranks the same as a 100 kg lifter benching 143 kg (ratio: 1.43x). This is the same approach used in competitive strength sports through formulas like Wilks and DOTS.
For weighted pull-ups, enter only the added weight (not your body weight). The calculator adds your body weight to the loaded weight before calculating the 1RM and ratio. For example, if you weigh 80 kg and do pull-ups with a 20 kg plate, enter 20 kg as the weight lifted.
The most effective approach is progressive overload: gradually increasing weight, reps, or sets over time. Focus on compound movements, eat enough protein (1.6-2.2g per kg of body weight), sleep 7-9 hours, and follow a structured program. The GROOVE app tracks all of this for you and shows your rank update in real time after each workout.
