Peak Watts

By the Watta Team · Updated

Peak Watts: Peak watts is the highest power output recorded in a single stroke on a rowing ergometer, reflecting your maximum explosive power.

What is Peak Watts?

Peak watts is the maximum power produced in any single stroke during a rowing session. On a Concept2 PM5 it appears in the workout summary as the highest watts recorded. Peak watts reflect maximal leg drive, explosive hip extension, and fast-twitch muscle recruitment. Because it is a one-stroke maximum, it is strongly correlated with strength and body mass: elite heavyweight men can exceed 900-1,000W, elite lightweight men 700-850W, and elite women 550-750W. Trained recreational rowers typically peak between 400-600W. Peak watts are useful for tracking neuromuscular power, but average watts determine race performance. A high peak-to-average ratio indicates inconsistent pacing; a ratio above 0.85 suggests very even output. To improve peak watts, use short maximal sprints (10-20 seconds), standing starts, and heavy strength training such as squats, deadlifts, and cleans.

How Watta Uses Peak Watts

When visible on the PM5 summary screen, Watta can capture peak watts alongside average watts. This data provides context for the workout intensity profile and helps track changes in maximal power output over time as part of your overall training progression.

Frequently Asked Questions

What are peak watts on a rowing machine?
Peak watts are the highest instantaneous power output recorded in a single stroke during a rowing workout. They reflect your maximum explosive power, not your sustainable power.
What is a good peak watts on the erg?
For recreational rowers, 400-600W is a solid peak output. Club-level competitive rowers typically peak at 600-800W. Elite male rowers can exceed 900-1000W on a single stroke. Peak watts vary significantly with body size and strength.
How do I increase my peak watts?
Short, maximal-effort pieces develop peak power: 10-second sprints, standing starts, and heavy resistance work on the erg (high drag factor). Off-erg strength training — especially squats, deadlifts, and power cleans — builds the leg drive power that translates to peak watts.
Does peak watts matter more than average watts?
For racing performance, average watts matters more because it determines your overall time. However, high peak watts indicate the explosive capacity needed for starts, moves, and sprints. Ideally, you develop both through a balanced training programme.

Average WattsAverage watts is the mean power output sustained across an entire rowing workout or interval, providing a single number to summarise overall intensity.Watts (Rowing)Watts in rowing measure the power output on an ergometer, calculated from the pace using the Concept2 formula: Watts = 2.80 / pace³.Force CurveThe force curve is a graph on the Concept2 PM5 that shows how much force you apply to the handle during each stroke, used to diagnose rowing technique.Erg SprintAn erg sprint is a maximal effort rowing piece over a short distance (100-500m) or time (under 2 minutes), used for testing peak power and anaerobic capacity.Split to Watts ConverterWatts to Split ConverterErg Interval Workouts2K Rowing Test GuideFor Competitive RowersFor CrossFit AthletesPower Intervals 10x200m
