How many sets per muscle per week? Counting hard sets

Training volume is how much work a muscle gets. A common way to count it is hard sets per muscle per week. Fortior counts them for you, so you can see where your sets are going without keeping a spreadsheet.

What counts as a hard set

Counting every set treats a light set and a demanding one as equal. A hard set is meant to count only the sets that were demanding enough to matter: close to failure, with enough reps to load the muscle. In Fortior, a hard set has at least 5 reps and at most 3 reps in reserve. Warm-ups never count, and neither does a set you did not complete.

Because a blank counts as 2, leaving reps in reserve empty on easy sets can inflate your hard-set count. Rating your effort keeps the count honest. See RPE and reps in reserve.

Primary and secondary muscles

Most exercises work more than one muscle. Fortior gives each exercise main muscles and helper muscles. A hard set earns one full set for each main muscle and half a set for each helper.

For example, the barbell bench press lists the chest as its main muscle, with the triceps and front delts as helpers. Four hard sets of bench press add up like this:

• chest: 4 sets,
• triceps: 2 sets,
• front delts: 2 sets.

That is why a muscle's total can include halves, such as 6.5 sets, and why a muscle can show work even if you never trained it directly.

How many sets per muscle per week?

There is no single number that suits everyone. The right amount depends on your experience, the exercises you choose, how hard you train each set, and how well you recover. Coaches often describe volume in three landmarks, and Fortior shows your weekly hard sets against them:

• MEV, minimum effective volume: roughly the least weekly volume generally thought to be enough to make progress.
• MAV, maximum adaptive volume: the range generally considered most productive.
• MRV, maximum recoverable volume: roughly the most you can recover from.

Fortior's bands are based on the volume landmarks published by Renaissance Periodization. They are general defaults for a population, not limits measured for you.

All numbers are hard sets per week. Muscles without a band, such as abs and forearms, show "No band". A weekly total is labeled Below MEV, Maintenance (at or above MEV but under the MAV range), In MAV, Near MRV (above the MAV range, up to MRV) or Over MRV.

Two ways Fortior shows volume

• Body-Part Workload. Counts every completed non-warm-up set, whatever its reps or effort, over 7 days, 4 weeks or 12 weeks. You can switch between sets and load volume (weight × reps). Helper muscles count as half.
• Weekly hard sets against the bands. Counts this week's hard sets for each muscle and compares them with MEV, MAV and MRV. It also shows a smoothed sets-per-week figure that blends recent weeks.

The workload view is free. The weekly comparisons are part of Fortior Premium.

What the numbers cannot tell you

• No coverage is not proof of neglect. A muscle with no coverage just has no logged work mapped to it. Work done outside Fortior does not appear.
• Set counts are an attribution aid. They are not a direct measure of muscle growth or fatigue, and different exercises are not perfectly comparable.
• The bands are population defaults. Your own response to volume may sit above or below them.

Volume figures are estimates based on your own logs and are educational. They are not personal targets, and Fortior is not medical advice.
