Data points provided by the Metric VBT app

There are a number of metrics and data points that can be used to assess your training. Depending on your training goals and exercise selection, you can adjust the displayed metrics to suit your context.

Load lifted

You can enter the amount of weight lifted in either kilograms (kg) or pounds (lbs).

Reps completed

For velocity tracked exercises, Metric will automatically count and log your completed reps for each set, while for manual entry exercises you can enter the number of reps before marking each set complete.


RPE and RIR logging is an optional feature available for lifters. You can enable this via Account → Training preferences.

Mean velocity (m/s)

Measured in metres per second (m/s) mean velocity is the average speed of the barbell during the concentric (up) phase of a rep. A higher mean velocity signifies greater power and force generation, while a decrease in velocity can indicate fatigue or low intent on your lifts.

Best rep velocity (m/s)

Best rep velocity is the speed of your fastest rep (usually the first or second rep) in a set. This is a useful indicator of your most explosive output during the set and is useful as an indication of nervous system fatigue or readiness. Best rep velocity is available for both peak and mean velocity.

Average velocity (m/s)

Average velocity represents the combined average velocity for all reps in a set, giving you an overall view of your performance consistency and endurance throughout the set. Average velocity is available for both peak and mean velocity.

Velocity loss (%)

Velocity loss is a measure of the drop in velocity from your fastest to your last rep in a set. The higher your velocity loss value the more strenuous a set is and the closer you went to the point of failure. Available for both peak and mean velocity.

Range of motion (ROM) (cm)

ROM quantifies the distance the barbell travels during the concentric portion of the repetition from the lowest to the highest point in each rep, measured in centimetres.

Eccentric tempo (sec)

Eccentric tempo captures the duration of the eccentric (lowering) phase of each rep in seconds. Monitoring this helps in maintaining controlled and consistent lifting techniques. A longer tempo is often desired during rehabilitation training or when training for hypertrophy and muscle building.

Consistency (%)

Consistency is a calculated score for measuring the stability of your eccentric tempo or ROM across all the reps in a set. Higher consistency percentages (above 95%) indicate better technique and control.

Peak velocity (m/s)

Peak velocity is an alternative measurement the shows the highest moment of barbell velocity during a repetition. Useful for explosive lifts like snatch, clean, and jumps peak metrics providing insights into the maximal explosive effort exerted.

Mean power (W)

Mean power is calculated similarly to the mean velocity of a repetition but taking into account the load on the bar to provide a value in term of watts produced. Power is a preferred metric when training specifically for improved explosive output and power generation.

Peak power (W)

Peak power takes the peak velocity moment from a repetition and calculates the peak watts produced at this same moment.

Customising your metrics

While Metric VBT offers a wide range of metrics, you have the flexibility to tailor the app to your needs. You can customise the data displayed on both the workout page and in the set review highlights and rep-by-rep table.

Within the ellipses menus on each page, you can tailor the default metrics shown for all exercises or set specific metrics for each individual exercise to suit your training goals and objectives.
