Training metrics
Every metric Metric tracks — what it means, how it's calculated, and when it's the right signal.
Metric tracks velocity, power, range of motion and tempo on every rep, and rolls them up into per-set, per-exercise and across-session views. Most lifters use 2–3 metrics as their primary signals; the rest are useful in specific contexts.
This page is the quick reference. For a deeper explanation of each metric — what it means, how to use it, and the values to expect — read the full rep metrics guide.
Mean velocity, range of motion, and eccentric tempo are available to all users. All other metrics require a Pro membership for access.
Per-rep metrics
Velocity
Mean velocity (m/s). Average bar speed across the concentric phase. The standard signal for most lifters and most lifts — use it as your default. Most useful on heavy strength work where the load is slow enough that average speed is meaningful (typically below ~1.0 m/s).
Peak velocity (m/s). Maximum bar speed during the concentric. Always higher than mean. Best for explosive movements — loaded jumps, dynamic-effort speed work, Olympic lifts. Set it as the default-displayed metric per exercise where it’s the better signal.
Some lifters stay with mean velocity for everything — peaks can be noisy and the two correlate strongly. Either choice is fine.
Time to peak velocity (s). How long after the rep starts you hit peak velocity. Shorter = faster rate of force development. Useful for explosive movement quality and for sprint or power athletes.
Power
Mean power (W). Mean velocity × load × gravity. Useful when total power output is the goal — power-development blocks, athlete-focused training.
Peak power (W). Same calculation using peak velocity. The headline number for “how explosive was that rep” on jumps and ballistic work.
Eccentric power (W). How aggressively you decelerated the bar during the eccentric phase. High = you pulled the bar down hard (drop catches, fast descents). Low = passive lowering. Used for drop-catch training, eccentric-overload work, and confirming a tempo eccentric was controlled rather than dropped.
Range of motion
Range of motion (cm). Vertical distance of the concentric. Best as a relative metric — set-over-set or rep-over-rep — to track technique consistency or detect drift across a fatiguing set.
ROM measures plate displacement, not hip or body displacement.
Tempo
Metric splits each rep into four phases. They’re useful for tempo work where you’ve prescribed a specific tempo and want to confirm execution.
Rep duration (s). Total time from rep start to rep end — the sum of the four phases below.
Eccentric duration (s). Time from the start of the rep to the bottom of the lift.
Bottom pause (s). Time spent stationary at the bottom before the concentric starts.
Concentric duration (s). Time from the start of the concentric to lockout.
Top pause (s). Time spent stationary at the top before the next rep’s eccentric.
Manual entries
Load (kg or lb). Entered before or after the set. Required for power, e1RM and load-based PRs.
RPE / RIR. Optional, logged after the set. Useful for autoregulation alongside velocity. See RPE & RIR.
Per-set metrics
After the set, Metric calculates set-level aggregates and shows them in the set highlight bar on the set summary screen:
- Total reps
- Set averages — mean across the set for every per-rep metric you have on
- Best rep — the rep with the highest mean (or peak) velocity, depending on your default
- Velocity loss (%) — drop in mean velocity from the first rep of the set to the last. Standard autoregulation cue for stop-set rules. Small loss (~10%) biases toward strength/speed; larger loss (~30%) biases toward hypertrophy.
Per-exercise (workout level)
For each exercise within a workout, Metric rolls metrics up across all sets of that exercise:
Estimated 1RM (kg or lb). Predicted one-rep max from your load-velocity profile plus the current set’s data. See Estimated 1RM.
Max power (W). Highest power output reached across the exercise, sourced from your load-power profile.
Session tonnage (kg or lb). Total load × reps for the exercise this session.
Total time under tension (s). Sum of rep durations across the exercise.
Trend metrics across sessions
- Velocity trend — mean velocity at a given load over time. See Velocity trends & readiness.
- Personal records — best load, mean velocity, peak velocity, mean power, peak power, and e1RM per exercise. See Personal records & PR badges.
Which metrics matter for which training style
| Training focus | Primary signal | Secondary |
|---|---|---|
| Heavy strength | Mean velocity, e1RM | RPE, velocity loss |
| Speed / power | Peak velocity, peak power | Time to peak velocity |
| Hypertrophy | Velocity loss | RPE, mean velocity |
| Olympic lifting | Peak velocity, peak power | Bar path, rep duration |
| Athletes (S&C) | Mean and peak velocity, eccentric power | Power, e1RM |
| Tempo / technique | Rep duration, phase splits | ROM, bar path |
Set per-exercise defaults in Per-exercise preferences so the right metric is on screen for each lift.
Customising what’s displayed
Every screen showing metrics is configurable. By default, the set summary shows mean velocity, ROM and eccentric tempo. Swap in any of the available metrics app-wide or per-exercise via Customisation.
Coach access
In Coach Mode, all metrics are available per-athlete. The team leaderboard sorts the roster by any single metric. See Team leaderboard.
Export
All metrics are columns in the data export. See Exporting your training data.
