Problem

Currently, the Strength Workout Builder defaults to imperial units (lb), even when:

The user’s account settings are set to metric
The endurance side of TrainingPeaks correctly operates in metric

While it is possible to manually change units within individual exercises or workouts, this is not persistent and must be repeated each time.

This creates a system-level inconsistency and repetitive manual overhead.

Why This Matters (Practical Impact)

For coaches operating in metric regions (Australia, UK, EU):

Requires manual unit switching for every workout or exercise
Introduces unnecessary cognitive load (constant kg ↔ lb awareness)
Increases risk of programming errors
Creates workflow friction at scale (especially with multiple athletes)
Results in a disjointed athlete experience (mixed unit systems)

In practice: endurance = metric, strength = manually corrected every time → breaks flow and efficiency

Current Behaviour
Account set to metric → works correctly for endurance workouts
Strength Builder → defaults to lb
Units can be changed manually per exercise/workout, but:
Not persistent
Not inherited
Not scalable
Expected Behaviour

The Strength Workout Builder should support persistent unit preferences.

Option 1 (Preferred): Global Inheritance
Automatically inherit units from:
Account Settings → Unit Preferences
Option 2: Strength-Specific Default Toggle
Provide a single setting within Strength Builder:
Default units = kg / lb
This setting should:
Apply to all new workouts
Persist across sessions
Remove the need for repeated manual changes
Why This Is Important (Product Perspective)

This is not about adding functionality, it’s about removing friction from an existing one.

It directly impacts:

Workflow efficiency (core product promise)
Adoption outside the US
User trust in system consistency
Scalability for coaches managing multiple athletes

Current behaviour solves the problem technically, but not operationally.

Suggested Enhancement (Best Implementation)
Link Strength Builder unit defaults to:
Account Settings → Unit Preferences
OR introduce:
Persistent “Default Unit” setting for Strength Workouts

Ensure:

All input fields default correctly (kg)
Athlete view reflects consistent units
Future analytics respects the same unit system
Optional Future Improvement
Allow per-athlete unit overrides for international coaching scenarios
Summary

This is a small change with disproportionate impact:

Eliminates repetitive manual steps
Reduces programming errors
Improves global usability
Aligns strength with the rest of the TrainingPeaks ecosystem

Right now, the system requires constant correction.
This feature would make it correct by default.
