Workout with your Concept 2, WaterRower or FluidRower rowing machine. Be guided by world-class athletes and instructors. Follow structured training programs to improve yourself and your times or just choose your own workout. asensei customizes challenges to meet your capability and pushes you to your potential.

asensei guides and monitors your practice on and off your rowing machine. More than a workout, this is a series of lessons - build strength and fitness alongside skill and technique as you are guided, monitored and corrected through these programs by your very own personal coach, asensei.

asensei talks to the monitor on your rowing machine. She reads force curves, analyzes your performance and uses that to inform your practice. Are you losing power at higher stroke rates? Are you losing length when you’re tired? Do you find it hard to hold lower stroke rates consistently? Are you rushing the recovery? Compensating for poor leg drive with over-use of your arms?

asensei knows. And she’ll be sure to let you know.

Practice. Perfected.


PROGRAMS, PERSONALIZED: there's a program for you whether it's a 2km, 6km or 30min challenge you are looking for. Designed to challenge, improve and adapted for you.

COACHING, UNPARALLELED: Say hello to the world´s best coaches. Olympic Gold Medalist Eric Murray, British Rowing, Johan Quie, Shane Farmer of Dark Horse Rowing. They set the work; asensei makes it work for you. Watching, responding, adjusting, encouraging - just as they would.

ANALYSIS, DELIVERED: Row - record - watch - rewind - remember. The old ways are over. asensei watches you move, as you move, responds in the moment and evaluates over time.


* Beginners - if you are new to rowing learn correct technique and be challenged as you workout.
* Intermediate rowers - refresh your skills, learn new tips, get back into the groove and take things to the next level.
* High-school or college athletes who wish to get win a seat in the boat, get recruited, or compete nationally and internationally.
* Indoor Rowers or Crossfit (TM) athletes who wish to improve their indoor rowing technique and scores.
* Those who want to get fitter and stronger with the excitement of a studio fitness class and the attention of a personal trainer


Requires a compatible rowing machine:
* Concept 2 with a PM5 performance monitor
* WaterRower with an S4 performance monitor and a Bluetooth ComModule
* FluidRower with a Bluetooth console.

We connect to the Health app to monitor heart rate on some workouts.


“I was fortunate enough to have great coaches from the very beginning of my rowing career. This meant I wasn’t taking thousands of bad rowing strokes, ingraining bad habits. The potential for asensei to provide quality feedback before bad habits are formed is really exciting", Helen Glover, 2x Olympic Gold Medallist and World #1 Rower.

"Just when you thought (sports) technology couldn't get any cooler, along comes asensei", CBS Television

"... the next frontier in the fitness tech revolution ... a wildly ambitious goal ... able to guide you through everything from form and recovery to metrics and goals while improving your individual results ... future of personal training", Men's Health

Here's what users had to say:

"someone keeping an eye on you the whole time is really cool because ... it keeps you honest, keeps you on track in a way that I don't think a coach normally can unless you are doing a one on one session, so it was the benefit of a one on one, with the class dynamic, which I really like!"

"It's a cool product. I've never ever seen anything like that. In 5 minutes I learned how to row, I thought I was doing it right, but I wasn't"

"(asensei) said don't worry there's a bunch of exercises I'm going to give to you afterwards that are going to help you on that. ... that's amazing. ... this is not just about now, it's like building a relationship."

What’s New

Version 1.17.0


The post-workout sharing screen data is now more consistent with the entries in the Concept 2 Logbook.

The first workout stats card now displays only the 'active rowing' part of the workout and doesn't include rests, warmups or cooldowns. This means it reflects the 'performance' part of your workout rather than the overall session. This is consistent with the Concept 2 workout summary. Details below:
* TIME - duration of your rowing during the active rowing part of a workout
* AVE SPLIT TIME - your average split time during the active rowing part of a workout
* DISTANCE (M) - distance rowed during the active rowing part of a workout
* CALORIES - calories burned during the active rowing part of your workout.

Overall session details are still captured and broken out on a second stats card.
* OVERALL TIME is the total duration rowed in the workout, including active rowing and rowing during rest periods, warmups and cooldowns.
* OVERALL DISTANCE is the total distance rowed in the workout, including active rowing and rowing during rest periods, warmups and cooldowns.
* REST TIME - is the time rowed during your workout, but excluding the active rowing - so this is your time spent in warmups, cooldowns and rowing in rest periods.
* REST DISTANCE - is the distance rowed during your workout, but excluding the active rowing - so this is your time spent in warmups, cooldowns and rowing in rest periods.

A third stats card shows some additional stats for your session. These are for the active rowing part of the workout only, not for the rests, warmups or cooldowns.

A 4th stats card is similar to the first stats card, showing details of the active rowing, but displays drag factor instead of calories.

Note that you may still see some discrepancies between the data shown on these cards and the PM5 since asensei does not reset the PM5 at the start or the end of a workout session. asensei does not capture any meters/time rowed outside a workout, even if the app is open.

Awesome, get the most out of your Concept 2

Before getting this app I was rowing my C2 aimlessly, poor technique, no goals, no coaching. I tried the free trial workouts that comes with the download. After 1 week I was hooked. The app connects easily with the C2 pm5, once connected, the app allows you to download a selection of free workouts, many more available with the paid subscription. A few things really impressed me. First, connectivity with the C2 is excellent and the app allows you to upload your workout and stats to your C2 logbook. Second, the app provides the rower with a human connection. Instead of relying on graphics, you actually get to see a real rower on his C2 doing the same workout that you’re doing. For me that was what got me hooked. I actually got to see what I was doing wrong, and by listening to the coach and copying his movements I was able to dramatically improve my rowing technique. Third, unlike other rowing app, this one records your performance as you progress and provides you with target goals based on you specifically. Lastly, the customer service is excellent. When I purchased my subscription I must have done something wrong and my subscription didn’t download to my app. I wrote a brief email and the next morning everything had been sorted out. Like all app, you need to read the FAQ provided by the developer, in this case, the FAQ is extensive and covers about everything. I’m not into sharing workouts and stats with others, but if it’s your thing the app also provide that possibility. Although I have not tried it, there is an online presence on Facebook and also some live workouts. I strongly encourage you to give this app a try.

Empty the tank

Just getting back into my rowing - not as strong as I was so work to do, but emptying the tank as o go the reminders to push harder and debriefs are helpful!

Overall good guide for training

Just got feedback from Asensai. I am very pleased that what I had posted on my comment was taken into consideration (probably many more reviews included these comments). If they pull through with the features I will update to 5 stars.

I’m new to rowing and just bought a concept 2 with a PM5. Very easy to set up, application is very easy to follow.

Did the 6 week program with Eric and had fun. Workout plan is well guided and I did improve very much.

Very happy with the program.

Future recommendations:
-Allow user to move the time bar to skip certain parts of the training (ie the warm up comes repetitive).
-allow for choice of music or allow Spotify or Sirius XM to play in background.
-hopefully add more programs for training.

Developer Response ,

We definitely want those five stars!

Update to latest version of app; you can now skip many parts of a workout including titles, warmups and rests. We don’t let you skip the hard work though!

If you visit you’ll see over 40 new lessons from Shane Farmer of Dark Horse Rowing. Eric Murray is working on new programs with as we speak and we will be releasing some new workouts from Coach JQ!

Music — we’re collecting customer preferences from Spotify, Pandora, Apple Music and/or local music on your iPhone to prioritize what we do next!

We so appreciate your support and encouragement! You make asensei better, she will make you better!
