Rowing on Concept2 rower is so enjoyable and have been doing it for the last few months. All this while, I was doing intervals (500m or 1000m followed by 1 min rest, repeat). For the last 2 days, decided to try endurance training. Happy to see that I can hold a moderate pace for 30 minutes and rack up ~6500m. Will continue this for some time before going back to intervals.
