How much UT2 do you need to do? Low intensity training has a “dose-response curve” - basically because you don’t accrue much residual fatigue you can keep adding more volume and keep getting more benefit… to a point. Which means your total volume should reflect where you’re at in your training and your goals. Most masters rowers will get great results on 3-5 hours of UT2 per week (~3 sessions of 60-90 minutes). Elite rowers need substantially more. There is no fixed number - you should aim for a
