A whole new dimension to the water rower

Water Rower without Ergatta - once or twice a week… boring. Water Rower with Ergatta - every freakin’ day - Fun!!!

Addictive work out!

I’ve had a WaterRower for a year and loved it but getting the Ergatta upgrade takes it to the next level. It manages to be fun and hard at the same time! I look forward to working out!

Good experience high price

Using Ergatta has made rowing a lot more enjoyable and effective as an exercise. However the monthly subscription rate is incredibly high when you compare it to peloton or other content providers put out: large numbers of live and recorded workouts for numerous fitness regimen’s with professional trainers for only $10 more a month. I think if you can’t get the price down long-term to what is commensurate for what you are offering, which is a good yet limited service, it will be hard to build up and sustain a large number of subscribers.

Best addition well worth it

I used the water rower intermittently after buying it but found that without a readout that really made sense to me and that allowed me to keep track of my progress it just wasn’t as good as the treadmill. Now, w the addition of the Ergatta I have turned this workout to a daily routine of 60 min/session. I can look at my historical data, compare it, and each race allows me to focus on improving.
The only thing missing is the Apple Watch connectivity for the hear rate. But they say it’s comming; my guess is that they need to write the program a new so might be comming for awhile.
Still. Great purchase.

Motivating rowing experience

The gaming/stat/comparison experience that Ergatta offers has been very motivational to keep me consistent with the water rower. We have wanted to purchase a water rower for sometime but my concern has been that it would become another piece of rarely used equipment like other exercise equipment has become. My treadmill gets used "maybe" once a week on average.

The Ergatta program has me coming back to complete challenges, races, and workout programs consistently. It really is impressive how this detail can motivate me to be consistent in my workout routine.

Thank you Ergatta team!
