I am considering a skierg for the house but have limited experience with one. I seem to only see them used for intervals but would like to know if anyone uses them for long steady state sessions a few times per week. We've had an elliptical for a long time but its starting to get worn out. I feel like a treadmill is a waste when I can just open the front door - same with a bike. I've considered a rower too but my butt always goes numb after a while.
