Why You Need 5 Metrics Per Exercise

Not all exercises are created equal. A barbell squat and a plank have completely different success metrics. That’s why Workout Lab lets you track up to 5 custom metrics per exercise.

The Problem with One-Size-Fits-All

Most fitness apps assume every exercise follows the same pattern: sets × reps × weight. But what about:

• Timed holds (planks, wall sits)
• Distance movements (farmer’s walks, sled pushes)
• Bodyweight progressions (where leverage matters more than added weight)
• Cardio intervals (where heart rate and time are key)

Workout Lab’s Approach

When you create an exercise in Workout Lab, you choose which metrics matter:

Weight-Based Exercises

• Weight
• Reps
• Sets
• RPE (Rate of Perceived Exertion)
• Rest time

Timed Exercises

• Duration
• Sets
• Heart rate
• Rest time
• Distance (if applicable)

Cardio/Conditioning

• Duration
• Distance
• Pace
• Heart rate
• Calories

Real-World Examples

Example 1: Barbell Squat

• Weight: 315 lbs
• Reps: 5
• Sets: 3
• RPE: 8
• Rest: 3 minutes

Example 2: Farmer’s Walk

• Weight: 100 lbs per hand
• Distance: 50 meters
• Time: 45 seconds
• Sets: 4

Example 3: Plank

• Duration: 90 seconds
• Sets: 3
• Rest: 60 seconds

Setting Up Your Metrics

1. Create a new exercise or edit an existing one
2. Tap “Customize Metrics”
3. Select up to 5 metrics that matter for this movement
4. Save and start tracking

The flexibility means you can track exactly what matters for your training style, whether you’re a powerlifter, CrossFitter, or general fitness enthusiast.
