Volume landmarks for hybrid athletes: MEV, MAV, and MRV
Key points
- Volume is the single biggest driver of muscle growth, but only up to a point. Past that point, more sets means more fatigue and less progress.
- Three numbers describe the useful range for any muscle group: MEV (minimum effective volume), MAV (maximum adaptive volume), and MRV (maximum recoverable volume).
- For most muscles, MEV is around 8 sets per week, MAV is 12 to 20, and MRV starts around 20 to 25. The productive zone is MAV. Below MEV is wasted, above MRV is destructive.
- Hybrid athletes shift the landmarks down on the lower body, because running eats into recovery for legs. Upper body landmarks stay close to a non runner’s.
Why this matters
If you have ever stalled on a programme, the answer was almost always one of two things: not enough volume, or too much. Volume is the dial that drives most of muscle growth in trained lifters. The frequency and load matter, but they matter through volume. Get volume in the right band and you grow. Get it too low and you maintain. Get it too high and you regress.
The volume landmark framework, popularised by Mike Israetel and the Renaissance Periodization team, gives you three numbers per muscle group that turn this into a programmable problem instead of a guess. We use it inside Loonstep to size the lifting side of a hybrid programme to whatever running volume is on the other side.
This post defines the three landmarks, shows what they look like in practice, and explains how to shift them when running mileage is in the picture.
The three volume landmarks
MEV: Minimum Effective Volume
MEV is the smallest weekly set count that still drives growth. Below MEV, the muscle gets stimulus but not enough to push adaptation past maintenance. For most muscles in a trained lifter, MEV sits around 6 to 8 working sets per week.
If a programme prescribes only 4 to 6 sets per muscle per week, it is below MEV for most people. You will maintain. You will not grow.
MAV: Maximum Adaptive Volume
MAV is the productive range. This is the band where each additional set still adds growth, and recovery can keep up. For most muscles, MAV is 12 to 20 working sets per week.
Inside MAV, more is more, up to a point. The dose response curve is real but not infinite. The early sets in a muscle group’s weekly count drive most of the gain. The later ones still help. The very last few help a little, and at some point a single extra set switches from “added stimulus” to “added fatigue.” That is the upper edge of MAV.
MRV: Maximum Recoverable Volume
MRV is the ceiling. Past this, you cannot recover from the work you are doing, and progress reverses. MRV depends on the muscle, the lifter, and the rest of the training week. For most muscles, MRV starts around 20 to 25 sets per week, and it is reached during a peak phase, not held there indefinitely.
The whole point of a mesocycle is to ramp from MEV toward MRV across 4 to 6 weeks, then deload. You start near MEV in week 1 with low fatigue and clean weights. You build into MAV through the middle weeks. You touch the lower edge of MRV in the final loading week. Then you cut volume in half for a deload week and reset.
How the landmarks look in a table
| Muscle group | MEV (sets/week) | MAV (sets/week) | MRV (sets/week) |
|---|---|---|---|
| Chest | 8 | 12 to 20 | 22 |
| Back | 10 | 14 to 22 | 25 |
| Quads | 8 | 12 to 18 | 20 |
| Hamstrings | 6 | 10 to 16 | 18 |
| Glutes | 4 | 8 to 16 | 18 |
| Shoulders (side delts) | 8 | 12 to 20 | 25 |
| Biceps | 8 | 12 to 20 | 22 |
| Triceps | 6 | 10 to 18 | 22 |
These are starting estimates. Individual variation is real. Use them as a first calibration, not as gospel.
Two things to notice. Back and side delts handle higher volumes than most other muscles, because they recover well and respond to frequency. Hamstrings and glutes have lower MRVs, partly because they overlap with squats, deadlifts, and (for hybrid athletes) running. The numbers are not symmetric across muscles, and that asymmetry is part of why a balanced programme is more art than spreadsheet.
How the landmarks shift for hybrid athletes
This is where the framework gets interesting if you also run.
Upper body: barely changes
Running has almost no recovery cost on chest, back, shoulders, biceps, or triceps. The landmarks listed above apply unchanged. If your weekly running volume is 30 to 50 km, you can hit MAV on every upper body muscle group without trouble.
Lower body: lower MAV and lower MRV
Running uses your quads, hamstrings, glutes, and calves. It produces fatigue in those muscles. It also produces eccentric loading from foot strike that is qualitatively similar to lifting fatigue. The recovery budget is shared.
The practical adjustment for hybrid athletes who run 30 to 50 km per week:
- Quads MAV: 10 to 15 sets per week (down from 12 to 18)
- Hamstrings MAV: 8 to 12 sets per week (down from 10 to 16)
- Glutes MAV: 6 to 12 sets per week (down from 8 to 16)
- Calves MAV: 6 to 10 sets per week (down a little; running provides direct stimulus)
When mileage climbs above 50 km per week (during a marathon block), shift down further. Cut another 20 percent off lower body MAV. The lifting side becomes a maintenance tool until the race is done.
Upper body keeps its full landmarks throughout. There is no good reason to under load the bench press because you are running.
Why the asymmetry
This is the volume side of the same interference effect we covered in our piece on why concurrent training interferes. Two systems sharing a recovery budget. Lifting and running do not interact much in the upper body because running barely involves it. They interact a lot in the lower body, and the hybrid solution is to leave room for both rather than insist on full lifting volume in the lower half.
The practical takeaway: a starting volume per muscle group
For a hybrid athlete running 30 to 40 km a week and lifting four days, here is a reasonable starting weekly volume in week 1 of a mesocycle:
| Muscle group | Week 1 sets | Week 4 sets | Week 5 (deload) |
|---|---|---|---|
| Chest | 10 | 16 | 8 |
| Back | 12 | 18 | 9 |
| Quads | 10 | 14 | 7 |
| Hamstrings | 8 | 12 | 6 |
| Glutes | 6 | 10 | 5 |
| Shoulders | 10 | 16 | 8 |
| Biceps | 8 | 14 | 7 |
| Triceps | 8 | 14 | 7 |
The progression: ramp from week 1 into MAV across weeks 2 to 4, then deload in week 5 (or 6, depending on the mesocycle length). Add 2 to 4 sets per muscle per week, distributed across sessions, so no single workout adds 8 sets to one muscle.
Notice that the lower body (quads, hamstrings, glutes) is sized lower than the upper body. That is the running adjustment.
Common volume mistakes
Stuck below MEV
The most common volume mistake in trained lifters is being stuck below MEV without realising it. Six sets per week of chest work, three each on Monday and Thursday, looks reasonable. It is below MEV for most people. The lift maintains, does not grow.
The fix: count your sets. If a muscle is below 8 working sets per week, add 2 to 4 sets and watch the next mesocycle.
Mistaking warmups for working sets
Only sets at RPE 7 or above count as productive volume. The pyramid of light singles you do before squatting is not 5 sets, it is 0 sets toward weekly volume. We talk about this in detail in our piece on why we use RPE instead of percentages, but the volume implication is direct: when you count sets, only count the ones that pushed you.
Pushing past MRV “to be safe”
Some lifters reason that if MRV is the ceiling, they should keep adding volume until they hit it, just to be sure they are training hard enough. This is wrong twice. First, MRV is not always reachable, especially mid mesocycle. Second, the productive zone is MAV, not the upper edge of MRV. Past MAV, the dose response curve flattens, and past MRV it inverts. Adding sets at that point makes you weaker, not stronger.
The fix: ramp to MAV, hold there, deload before MRV.
Using whole body landmarks for individual muscles
A common error is reading “10 to 20 sets per muscle group per week” and applying that as a total weekly volume. It is per muscle group. A reasonable hybrid programme has 60 to 100 working sets per week, total, distributed across all muscle groups, with each individual muscle in its own MAV.
What to do this week
Pull out your last four weeks of training logs. Count working sets (RPE 7 or above) per muscle group per week. Compare against the table above.
If a muscle is below MEV: add 2 to 4 sets per week, distributed across your existing sessions. Most often this means adding a second isolation movement, not more compound work.
If a muscle is at MAV and you are progressing: do not change volume. Keep ramping reps and load via RPE based double progression.
If a muscle is at or above MRV and progress is stalling: cut volume in half for a week and reassess. This is a reactive deload. We covered the fatigue signals that trigger one in the concurrent training piece.
Loonstep sizes weekly volume per muscle automatically, factors in your current running mileage, and ramps the numbers across the mesocycle without you having to do the spreadsheet math. Sign up and the coach handles the volume bookkeeping while you train.
