## In short

A full lifting session runs about 40 to 80 minutes depending on both the day and the rest length chosen, averaging around 56 minutes across a four-day split at a typical default rest setting. Rest between sets is the largest single share of that time, at roughly half the clock, with warm-up, the working sets themselves, and about ten minutes of mobility work filling the rest.

- A full session runs 40 to 80 minutes depending on the day and the rest setting, averaging about 56 minutes across a four-day split at the default rest length.
- Rest between sets is about 48 percent of a session at the default rest setting, and even on the shortest setting it is still the largest single block on all 4 days.
- Set count moves the clock on its own: at the default rest setting a 21-set Push day runs about 56 minutes and a 23-set Pull day about 63.
- Warm-up costs about 8 minutes on a day that opens with a heavy barbell lift, and about 5 minutes on a day that opens with a carry, since a carry earns no ramp-up sets.
- Mobility adds about 10 minutes to every session, near enough the same on every day whatever the lifting itself took.

A full strength session runs 40 to 80 minutes, and almost none of that range is
guesswork. Once you know how many sets a day carries, how long each rest period is, and
what the warm-up and the mobility work add, the total is arithmetic rather than a guess
made mid-workout about whether you have time to finish.

## How long should a strength workout take?

Somewhere between 40 minutes and 80 minutes, depending on the day and the rest length
you choose. Across a four-day split, the average full session runs about 56 minutes at
the default rest setting. Counting every rest setting, the shortest day finishes in
about 41 minutes and the longest runs closer to 79.

That range is wide because two things move independently: how many sets the day
carries, and how long you rest between them. A day with fewer, lighter sets and short
rest can be done in under 45 minutes. A day with more sets on the heaviest rest tier,
rested in full, runs closer to an hour and twenty.

## Where does the time in a session go?

Four blocks: rest between sets, the working sets themselves, the warm-up, and the
mobility work at the end. Rest is the largest of the four by a wide margin. Take Push,
a 21-set day at the default rest setting, running about 56 minutes total:

| Block | Time | Share of session |
|---|---|---|
| Rest between sets | 27 min | 48% |
| Working sets | 10.5 min | 19% |
| Warm-up | 8 min | 14% |
| Mobility | 10 min | 18% |

Rest alone is close to half the clock. That is what a rest period is for. A muscle that
just did a heavy set needs the recovery time before the next one, and cutting that time
makes the next set worse. [Rest between sets](/blog/rest-between-sets/) covers why rest
length is scaled to the exercise rather than fixed at one number.

## Why does session length vary so much by day?

Set count and rest tier mix account for most of it. At the default rest setting a
21-set Push day runs about 56 minutes and a 23-set Pull day about 63. A day where most
of its sets sit on a 180-second rest tier runs longer than one where most sit on a
90-second tier, even at the same total set count.

The opening lift adds a smaller but real difference. Only a lift that is rep-based and
loaded with weight earns ramp-up sets in the warm-up, climbing from 40 to 80 percent of
the working weight before the first working set. A day that opens on a distance-based
carry skips that step entirely, since there is no percentage of a working weight to
climb toward. That difference is about three minutes. The warm-up's cardio block is a
3-minute clock; the dynamic drills and the ramp-up rungs are untimed, so the totals are
estimates: roughly 8 minutes on a day that opens with a barbell lift, and about 5
minutes on a day that opens with a carry. [The warm-up that works](/blog/warm-up-that-works/)
covers the ramp-up rule in full.

Mobility adds about 10 minutes, near enough the same on every day whatever the lifting
portion looked like. That makes it proportionally a bigger slice of a short day than a
long one.

The same arithmetic runs in reverse during a lighter week. Cutting sets and reps rather
than skipping the day entirely shortens the session itself, since fewer sets means less
total rest and less total working time on top of it. [When to deload](/blog/when-to-deload/)
covers when that trade is worth making.

## How long does each day take?

Between 41 and 79 minutes, depending on the day and the rest setting. Every day's length
is computable from the plan, given its set count, its mix of rest tiers, and its opening
lift.

| Day | Working sets | LONG rest | NORMAL rest (default) | SHORT rest |
|---|---|---|---|---|
| Push | 21 | ~69 min | ~56 min | ~49 min |
| Pull | 23 | ~79 min | ~63 min | ~54 min |
| Legs | 23 | ~78 min | ~62 min | ~54 min |
| Auxiliary | 24 | ~55 min | ~45 min | ~41 min |

Each figure includes rest, an estimated 30 seconds of working time per set, the day's
warm-up, and 10 minutes of mobility. Auxiliary is the shortest day at every rest
setting despite carrying the most total sets, because it opens on the farmer's carry
rather than a barbell lift and skips the ramp-up step, and because more of its sets sit
on lighter rest tiers than the heavy compounds on Pull and Legs. Pull and Legs run
longest: Pull carries three lifts on the full 180-second tier, Legs two.

The 30-seconds-per-set figure is a rough estimate. Real working time varies by rep count
and by how quickly you rack the bar, so treat the totals above as a close approximation
rather than a stopwatch guarantee.

## Does a longer rest setting really cost that much time?

Yes. Moving a day from SHORT to LONG rest adds 14 to 25 minutes depending on which day
it is, purely from the rest tiers stretching back out. Pull sees the largest swing,
about 25 minutes, because it carries three lifts on the heaviest rest tier. Auxiliary
sees the smallest, about 14 minutes, since none of its lifts sit on the heaviest tier at
all.

The other direction of that tradeoff is real too: a 2016 controlled trial already
covered in [rest between sets](/blog/rest-between-sets/) found longer rest periods
produced more strength and more thigh muscle thickness than short rest over 8 weeks in
trained men, by letting each set be closer to fully recovered. A shorter session is
minutes traded against a measurable training effect.

## Why does time matter for sticking to a program?

Because a program that does not fit the day does not get repeated. A 2002 review of the
research on adult physical activity participation listed a perceived lack of time among
the correlates of adult physical activity whose evidence it re-examined, alongside
obesity and past exercise behavior. That review did not attach one universal percentage
to the barrier, and time constraints affect different people to different degrees, but a
program a person can fit into a day gets repeated, and one that does not tends to get
skipped, whatever its content.

Whether a longer session works better in a controlled trial is a separate question from
whether it gets done.

## What does Compound do about session length?

Compound does not fix a session length or hide the tradeoff behind a default. The REST
LENGTH setting is a direct lever between recovery and total time: SHORT, NORMAL, and
LONG rest the same exercise at three different fractions of its tier, and the setting
says what each rest period becomes, in seconds. NORMAL is the default because it keeps
most of the recovery benefit of full rest while keeping a typical day inside about an
hour, but nothing stops a shorter session on a busy day or a longer one when there is
time to spend. Warm-up and mobility can each be switched off
entirely in settings, which is its own way of trading time for the parts of the session
that are not the working sets themselves.

## Common questions

### How long does a typical strength training session take?

About 40 to 80 minutes, depending on how many sets the day carries and how long you rest between them. A day with more heavy compound lifts and longer rest runs close to 80 minutes; a day built around lighter, shorter-rest work can finish in under 50.

### What takes up the most time in a workout?

Rest between sets, by a wide margin. On a typical day it accounts for close to half the total session time. The working sets themselves, the warm-up and the mobility work each take far less.

### Does a shorter rest setting actually save much time?

Yes. Cutting rest in half across a session saves 14 to 25 minutes depending on the day, since rest is the largest block of time to begin with. The tradeoff is recovery between sets, not just the clock.

### Why do some days take longer than others?

Mostly set count and how heavy the lifts are. A day with more total sets and more lifts resting on the longest tier runs longer even at the same rest setting. The day's opening lift also matters: only a lift that is rep-based and loaded with weight earns ramp-up sets in the warm-up, so a day that opens on a carry warms up faster.

### Does mobility work add much time to a session?

About ten minutes, near enough the same on every day. It does not scale with how many sets the lifting portion carried, so it matters more, proportionally, on a shorter day than a longer one.
