Is 20 Minutes on a Rowing Machine Enough?

For most people, yes: 20 minutes is enough to be worthwhile, particularly if you row regularly. It will not suit every goal, but it fits easily into a busy day and is far better than the longer session you never get round to.

What 20 minutes can do

Twenty minutes of steady rowing builds aerobic fitness and keeps you in the habit. Used for intervals, it makes a hard, efficient session. NHS guidance for adults is at least 150 minutes of moderate activity a week, or 75 minutes of vigorous activity, and rowing can count towards that. Three 20-minute rows is 60 minutes, so you would need other activity too, or longer sessions, to reach that figure. Treat it as a starting point rather than a ceiling.

What it will not do is guarantee weight loss or a particular calorie burn. Machine calorie estimates vary, so do not build a diet around them. If weight change is a goal, read rowing for weight loss.

How to use the time

Count the warm-up and cool-down inside the 20 minutes, so that every session has a shape. The free 20-minute erg workouts follow the same rule, if you want more sessions to choose from.

Session	Structure	Effort
Steady 20	3 min easy, 15 min steady, 2 min easy	4 out of 10, rate 18 to 22
Intervals	5 min warm-up, 6 x (1 min firm, 1 min easy), 3 min cool-down	Firm is 7 out of 10
Pyramid	4 min warm-up, 1-2-3-2-1 min firm with 1 min easy between, 2 min cool-down	Firm is 7 out of 10
Short sprints	5 min warm-up, 8 x (30 sec hard, 90 sec easy), 3 min cool-down	Hard is 8 to 9 out of 10

Keep technique tidy throughout. Quality strokes beat sloppy ones every time. If your form falls apart in the last third, shorten the hard efforts or slow down.

A week of 20-minute sessions

1. Two steady rows. These build the base and are easy to recover from.
2. One interval or pyramid session. Pick one and repeat it so you can see improvement.
3. Rest days. Take at least two a week at the start.

Once that feels comfortable, extend one steady row to 30 minutes before adding more intensity. If you can already row 15 minutes without stopping but longer rows will not fit your week, the Busy Rower 20-Minute Plan keeps every session inside 20 minutes.

When 20 minutes isn’t enough

If you are training for a longer event, such as a 5k or 10k, you will want longer sessions of 40 to 60 minutes at a steady pace, because the event is longer than any 20-minute piece. If you are preparing for a 2k test, your sessions need a mix of steady rows and hard intervals, and at least one session a week that is longer than 30 minutes. Our 5k and 10k benchmarks and 2k erg programme show how.

Making it count

• Warm up and cool down, within the time if you need to.
• Set a target, such as a distance or split.
• Do it often. Three sessions a week beats one long one.
• Rest properly. Recovery is when your body adapts.
• Track the result. A simple log shows you whether the same 20 minutes is getting easier.

Common mistakes

1. Going flat out for the full 20 minutes. It is likely to leave you sore and unwilling to repeat it.
2. Skipping the warm-up because time is short.
3. Never changing the session, so progress stalls.
4. Using 20 minutes as an excuse to do nothing else. Add strength work and a longer row when you can. Our comparison of rowing machines and gymnastics shows what bodyweight training can add.
