Editing an Exercise
To edit an Exercise, go to the 'Exercises' list and click on the pencil icon to open the Exercise Designer. This will load your existing Exercise details, which you can change and save. This will NOT automatically update this Exercise in existing Workouts but will reflect changes when added to Workouts going forward.

Details
Designing an exercise can have as much or as little detail as you want

As you complete workouts that include an exercise, you will gain insights on trends and deeper data analysis. See Analysis for details.

Exercises allow you to reuse them across multiple Workouts. As you perform exercises, Alero tracks your performance over time so you can view insights and trends.

Exercise trends help you understand how your performance changes over time, based on completed workouts rather than a single session.

Time period:
Trends are calculated using all workouts from the last 50 days. At least two completed sessions are required before a trend appears.

What is Volume?
Volume represents the total amount of work performed for an exercise during a workout.

Weighted exercises:
Volume = reps × weight for each completed set, summed across the workout.

Bodyweight exercises:
Volume is calculated using reps only, since no external weight is used.

Best Set:
For each workout, Alero identifies your best completed set. For weighted exercises, this is the heaviest set completed (or the highest reps at the same weight). This is used to calculate weight and rep trends.

How trends are calculated:
Each workout contributes one data point. Alero looks at how these data points change over time and calculates an overall trend direction across all sessions.

What do the arrows mean?

• ↑ Up – overall improvement
• → Stable – little or inconsistent change
• ↓ Down – overall decrease

What do the percentages represent?
The percentage shows the total change from the start to the end of the period, relative to your average performance. It reflects long-term trends, not individual workouts.

Small changes are shown as stable to avoid overreacting to normal day-to-day variation.

You can delete an exercise from the Exercise list. Deleting the exercise will remove it from your exercises collection meaning you will no longer be able to add to add to exercises and track information. However, if this exercise is in an existing workout won't be deleted from it.
