Workout with your Concept 2 rowing machine and be guided by world-class athletes and instructors. asensei tunes challenges to meet your capability and pushes you to your potential.

Introducing a new connected coaching app that lets world class coaches guide and monitor your practice on a Concept 2 rowing machine. asensei for rowing allows athletes to commit to engaging and effective coaching programs created and delivered by world-class athletes and coaches. 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 performance monitor on your Concept 2 rowing machine. She reads force curves. She analyses your performance and uses that to inform your practice. To inform the intent of 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.


ROWING, PERFECTED: row better, sooner. Every stroke, asensei analyses your performance and assesses your form. She coaches expertly and programs perfectly.

COACHING, UNPARALLELED: Say hello to the world´s best coaches. 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.

YOUR TEAM: Shatter a PB. Lead your crew. Make the games. Whatever training means to you, asensei will assemble the experts. Structured around your life, paced according to your progress, and with specialists on hand when you need them - every single session, every moment, every input is specific to you.


* 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 Concept 2 rowing machine with a PM5 performance monitor


“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 beta testers 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."

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 :)

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.

Two years ago, my husband and I bought a rower as our Christmas gift to one another. I used it faithfully for about a month and then didn’t really use it again until late the next summer when my two young boys cleaned my clock climbing our local mountain. Determined to get in shape after years of chasing after little kids and not exercising, I returned to the rower. It wasn’t until I heard about and started using asensei though that I truly started using the rower in the best way. As a mom of those two little boys who works and has a small farm, I don’t have the mental energy to design a workout plan. Asensei does that for me. The coaching is great! I love all the options and access to multiple coaches. This is the only exercise plan I have ever stuck with. I am set to hit my million meter mark just after the new year. I think asensei is definitely worth the price and their customer service is awesome!
