Better Than I Expected

I've owned my WaterRower for around 7 years and enjoyed the low impact cardio but didn't have a great way to push myself beyond my established pace. The gamification of Ergatta has pushed me more in just a few weeks than I had pushed myself in the past 2-3 years. Great tool, look forward to using it more.

Loving Ergatta

We have had a waterrower for a couple of years and enjoyed it. Then we upgraded with Ergatta - wow! We love it. We thought we worked out before but it was nothing like the extra push we get from ergatta - it is both fun and challenging and we are feeling in much better shape - who would have thought following a little orange ball could be so rewarding?!

Above and beyond expectations

We've had the water rower for over a year and I liked it but never found myself that eager to sit down for a row and never quite knew exactly how to structure a workout. Once we got Ergatta I'm totally addicted. I LOVE it and look forward to each session. I'm exhausted and sore (in a good way) my workouts are intense but low impact, work all my muscles and leave me just wanting more. THANK YOU for this amazing experience and stellar product!
The only thing I would wish for in an upgrade would be that the connection of the wiring and the screen mount seem a little flimsy. I worry that they will get bent or broken when we are putting up the rower/lowering it down. I would have preferred a removable tablet screen so we could leave the rower in the room where kids play. We've had to move it to the office because the screen sits just at the right height for a toddler to grab it when stored upright.
Other than that the experience of the program itself is amazing!

Best investment!

During the pandemic I located a water rower and it was a great product but being all alone it wasn’t giving me any motivation to keep going. I bought the Ergatta upgrade and I couldn’t be happier with it! I now have a few friends that have bought either upgrades or the whole unit and there is nothing better than competing with friends! If you are up in the air about buying it just buy it! You will enjoy and benefit from it!

Totally worth the investment

I have owned my Water Rower for several years and have used it and liked it. I got the Ergatta add-on in January and now I really use and I LOVE it. It makes it fun and if you're competitive, this will really help you. Trying to hit targets or improve your performance keeps it from being boring. You compete with yourself and compete with others. The Ergatta Facebook community is so supportive and it's inspiring to see others achieve goals and hit milestones. If you're thinking of buying a rower, this is the one. If you already own a Water Rower like I did, trust me - buy the Ergatta add-on.
