Training library / Metrics
Check what a Lifty Fifty metric counts, which units it uses and what it can tell you about your training.
The complete metric index
This reference catalogue groups measures by strength, hypertrophy, power and endurance, with further definitions for activity, consistency, mobility and stability. Lifty Fifty's four pillars are strength, endurance, mobility and stability.

Relative load, heavy sets and strength-focused work.
The number of working sets performed or planned at a heavy relative intensity.
Counts working sets whose load, expressed as a percentage of 1RM, meets the heavy-set threshold.
The number of working sets that fall inside the stricter strength-training load and repetition zone.
Counts working sets with high relative intensity and low repetition count according to the strength-zone rule.
The average relative load used across qualifying working sets.
Expresses the load of each qualifying working set as a percentage of its 1RM reference, then averages those percentages.
The total weighted volume accumulated from heavy qualifying work.
Adds load multiplied by repetitions across qualifying heavy working sets.
The number of distinct movements that contributed heavy strength exposure.
Counts each movement once, however many qualifying heavy sets it contains.
The number of sessions that included at least one heavy qualifying set.
Counts each session that contains at least one qualifying heavy working set.
A normalised workload score used to compare planned demand between sessions.
Combines relative intensity and planned repetitions across qualifying sets.
6 metric references
Working sets, muscle coverage and proximity to failure.
The working sets assigned to each primary muscle group.
Uses the movement reference to assign working sets to the primary muscle groups involved.
Working sets that meet the defined load and repetition criteria for hypertrophy-focused work.
Counts working sets with compatible relative intensity and repetitions inside the hypertrophy-zone rule.
The number of working sets logged or prescribed near failure using effort data.
Uses recorded or planned RPE or RIR to count sets that meet the near-failure threshold.
The number of muscle groups meeting the defined working-set target.
Counts muscles whose primary working-set total reaches the active coverage threshold.
The weighted volume assigned to primary muscle groups over a week.
A normalised measure for comparing planned workload between sessions.
Combines relative intensity and planned repetitions across qualifying sets.
4 metric references
Explosive movements, impact and power-focused sessions.
The number of working sets on movements classified as power, explosive, Olympic, or impact-oriented work.
Uses the movement reference to count working sets that qualify as power-oriented training.
The number of sessions that included at least one power-qualifying working set.
Counts distinct sessions with any qualifying Power work.
The number of distinct power-qualifying movements trained or planned.
Counts each qualifying movement once, even if it appears in several sets or sessions.
The number of working sets on movements classified as high impact.
Counts working sets on movements marked as high impact in the movement reference.
5 metric references
High-repetition resistance work and accumulated workload.
The total weighted working-set volume for muscular-endurance-relevant resistance work.
Sums load multiplied by reps for weighted, repetition-based working sets.
A workload score that weights repetition volume by relative intensity.
A workload score that weights volume by recorded effort.
The number of working sets performed or planned at a high repetition count.
Counts non-time-based working sets meeting the high-rep threshold.
The loaded volume accumulated from high-repetition working sets.
Adds load multiplied by repetitions across qualifying weighted, high-repetition sets.
6 metric references
The overall amount and distribution of recorded training.
The total number of logged sets in the selected period.
The total number of repetitions logged for repetition-based work.
The total load moved across weighted, repetition-based work.
The total wall-clock session time in the selected period.
A breakdown of recorded sets by muscle group and its role in each movement.
The number of distinct movements included in the selected period.
6 metric references
Training frequency, streaks and time between sessions.
The number of qualifying training sessions completed or planned in a week.
The number of distinct sessions in which each primary muscle group was trained.
The current number of consecutive weeks meeting the active consistency target.
The longest recorded run of consecutive weeks meeting the active consistency target.
The longest gap between qualifying training days in the selected period.
The number of distinct calendar days with qualifying training in a week.
4 metric references
Aerobic duration, intervals and the activities represented.
The number of sessions that included cardiorespiratory qualifying work.
The total duration of aerobic qualifying work.
The number of aerobic sessions using interval-style pacing.
The number of distinct cardio movements or modalities represented.
7 metric references
Movement range, planes and balance demands in the programme.
The number of distinct movements classified within full-range movement patterns.
The number of sessions that included mobility-qualifying work.
The number of distinct unilateral movements included in the selected period.
The number of distinct movements with moderate or high balance demand.
The number of sets meeting the defined criteria for mobility-related work.
The number of full-range movement patterns represented in the selected period.
The number of movement planes represented in the selected period.
6 metric references
Timed work, core and carry patterns, and controlled tempo.
The number of distinct time-based movements included in the selected period.
The number of core and carry movement patterns represented.
The total duration of timed stability-qualifying work.
The number of sessions that included stability-qualifying work.
The number of distinct movements classified as high balance demand.
The number of working sets with an explicit tempo prescription.
5 metric references
Coverage across resistance, aerobic, neuromotor and flexibility work.
The number of core training modalities represented in a week.
A yes/no signal for whether all four core modalities were represented in the week.
The number of weeks in a longer period where all four core modalities were represented.
The named modality categories absent from a week.
The number of qualifying loading and impact categories represented in the week. This describes training, not a measurement of bone health.

These are reference definitions, rather than a list of metrics displayed in every app view. Each calculation requires compatible training data. Counts describe work and coverage; they do not establish gains in strength, muscle, mobility or fitness. Work Demand is listed under both Strength and Hypertrophy, giving 56 per-pillar references.
