How long should a workout be

For almost everyone who is not a competitive athlete, a good answer is 20 to 45 minutes of actual work, two to four times a week. The number is small enough to be uncomfortable if you have been told otherwise.

Where the hour goes

Time an ordinary gym session honestly and the split usually looks something like this:

• Warm-up: 5 to 10 minutes
• Actual sets, with the weight moving: 8 to 15 minutes
• Rest between sets: 15 to 25 minutes
• Deciding, walking, waiting, phone: the rest

The work itself is a small share of it. This is why a focused 25 minute session can match an unfocused 75 minute one: you did not remove any sets, you removed the gaps.

What each length buys you

10 to 15 minutes

Enough for one circuit of three or four movements. This is a maintenance session. It will not add much, but it keeps the habit and the movement patterns alive, and on a bad week that is the entire job.

20 to 30 minutes

Three or four compound movements at real effort with real rest. This is where most people should live. It is long enough for meaningful volume and short enough to schedule without negotiating with the rest of your day.

30 to 45 minutes

The above plus accessory work for a specific goal: arms, calves, rear delts, whatever you are actually chasing. Useful once the basics are consistent.

Over an hour

Usually worth it only if you are training for something specific, or if a chunk of that hour is social and the social part is what keeps you coming back. That is a legitimate reason, it is just not a training reason.

What to cut first

When the session has to shrink, cut in this order:

1. Accessory work. Curls and calf raises go first.
2. Sets, not exercises. Three movements at two sets beats one movement at six.
3. Rest, carefully. Shortening rest raises the difficulty, so drop the weight slightly if you do this.
4. The warm-up, last. Two minutes of the movement you are about to do, unloaded, is a warm-up. Fifteen minutes on a bike is a hobby.

Consistency over length, every time

Four 25 minute sessions a week is 100 minutes of training. One 90 minute session is 90. The shorter plan wins on total volume, wins on recovery, and is far more likely to survive a bad week, which is the part that actually decides how the year goes.

If the problem is that you never know what to put in those 25 minutes, that is a different problem, and what workout should I do today covers it.
