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, 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 1.20.0

We say sayonara, or farewell, to the Hey asensei [+] button in this update. Some of you loved it, some of you hated it, and some of you never even figured out it was there! You can now find the main menu for asensei in the top right of the Up Next screen - we think this is more intuitive and works better in both portrait and landscape mode.

If you are looking for your Workout History that's now located under the menu item JOURNAL. We chose the name Journal because we want to bring you much more here in future - more post-workout stats and insights - watch this space! For now you'll find the usual list of workouts you have performed and can still tap into them to see more performance insights. Your programs and workouts can be found via the PROGRAMS menu item and settings are in the MY ASENSEI area. SUPPORT is located at the foot of the new menu.

We're planning further enhancements to the asensei rowing user experience in the coming months - it's all aimed at making asensei more enjoyable to use. Tell us what you like, don't like and would like us to improve via!


A bug that meant music (our default option) would not play correctly on iOS17 has been addressed.


Up Next screen menu changes:
* The menu button (three horizontal lines) in the top right replaces the Hey asensei [+] button in the bottom left.
* The JOURNAL menu item replaces the Workout History button (more insights will be added to this section over time).

Up Next screen visual refresh:
* Exercise name, coach name and program name now in cyan.


Tips and conversations updated to reflect the new menu structure.

Lots of helpdesk articles updated, but if you spot any we've missed let us know via

In the words of Huey Lewis - “I want a new drug”

Yes, after two sessions I can’t wait to get on my rower again. I just bought my first rower Concept2 during this pandemic. I tried it at the gym but wasn’t really thrilled. I looked at the Hydrow, which though is beautiful , but is heavy and had way to many workout choices. I couldn’t see my saying commuted to a monthly pay service until I found Asensei. Once I got my rower it sat there for a few days. I read the manual and lethargically tried to play a game. I was looking for a coaching experience like the hydrow on a lake and then I found Asensei. I thought I will give it a try. I tried it for the first time last night and when Eric said that try rowing three times a week, I was like no way, I am coming back tomorrow before I go to the gym. Great app. Yes the pairing was confusing as my iPad was already connected to ErgData, but I figured it out. Same goes for how to find settings such that I know how to upload to Concept2 logbook. The chat setting is not the most intuitive but once you figure it out. It is okay. I will be signing up soon :)

One of the best fitness apps out there

I purchased a Concept 2 rower about a year ago, and while I was using it on and off, I found it difficult to get into any kind of structured workout routine. It was difficult to get motivated to row.

So, I started to look for an accompanying app, and found Asensei. I have now been using Asensei for several months (first the free trial, then the paid subscription version). For me it ticks all the right boxes. Structure, motivation, teaching technique (useful even though I rowed in college - 2 decades ago - but valuable for all experience levels), and a good variety of training plans. It integrates seamlessly with my Concept 2, and accompanying logging software (Concept 2 logbook then to Strava and Garmin Connect).

It took a bit of time to get used to navigating certain parts of the app, finding the best programs etc., but overall it’s easy to use and comprehensive for my needs.

I haven’t tried all of the trainers (yet), but absolutely love Eric Murray’s workouts, and have just started another of his programs. He talks just the right amount, enough to motivate but not too much to become distracting/ annoying, and the variety of his workouts helps keep the training fresh. He’s also helping me to achieve new PBs.

So, while I rarely write reviews, I wanted to post this one to hopefully help others who may be looking for a tool to help take their rowing and fitness to the next level. Keep up the good work Asensei!

Terrific coaching, super high quality

I’ve had a Concept 2 tower in my basement for about a year, and while I’ve had fun hacking around on it, I knew there was more to rowing than my clumsy efforts. I just didn’t know how I would learn. As a former division 1 athlete (in a field sport, not in rowing!), I am used to being coached and am motivated by feedback and improvement. I was skeptical that an app could provide the coaching and feedback necessary for true form mastery (that might be an overstatement at this point, but I am getting there!) and performance improvement, but Asensei truly makes it happen. I am so impressed and delighted. Watching Eric through the workouts makes it easy to mimic good form and figure out where I have hang ups. He is a wonderful mix of low pressure and high motivation. This is truly an excellent stand-in for having an actual coach and an actual team to train with. It has made me want to try this out on the water! Thanks so much for delivering such a high quality experience.
