Volume Stats

Below the calendar grid, HyperIron shows aggregated volume statistics. Toggle between three scopes to see different levels of detail.

Daily stats

When you select a specific day:

• Exercises performed — List with set counts
• Sets per muscle — Bar chart showing effective sets for each muscle group hit that day
• Total effective sets — Sum across all muscles
• Tonnage — Total weight × reps for the session

Weekly stats

For the selected week (Monday–Sunday):

• Workouts completed — Count vs planned (e.g., "4/5 days")
• Sets per muscle — Horizontal bar chart aggregated across all workouts that week
• Compliance — Percentage of planned workouts actually completed
• Tonnage — Weekly total

This is the most useful view for checking whether you're hitting your volume landmarks.

Monthly stats

For the selected month:

• Total workouts — How many sessions you completed
• Average sets per muscle per week — Your weekly volume averaged over the month
• Training frequency — Average workouts per week
• Tonnage trend — Weekly tonnage shown as a trend line

How volume is calculated

Volume stats use the muscle activation model:

For each exercise:
  For each muscle in exercise.muscleGroups:
    effective_sets += logged_sets × (muscle_percentage / 100)

This means a set of bench press doesn't just count as "1 set" — it counts as partial sets for chest, triceps, and front delts, weighted by each muscle's contribution.

Example: Push day totals

Exercise	Sets	Chest	Triceps	Front Delts
Bench Press (100/60/40)	4	4.0	2.4	1.6
Incline DB Press (90/50/60)	3	2.7	1.5	1.8
Tricep Pushdown (0/100/0)	3	0	3.0	0
Day Total	10	6.7	6.9	3.4
