The gamification imo works well. Keeps you going without realizing the effort you're putting in.
I can really feel the full body effects and the gaming aspect keeps me motivated.
I find the Ergatta very motivating. I don't dread exercising any more!
The Ergatta's races and challenges and the whole system of gamification are more motivating to me than other kind of exercise. Also the Ergatta is a beautiful machine that fits in with my home aesthetic. Rowing is great exercise!
