Coaching Notes
- +The abbreviated warm-up means starting the first interval slightly conservatively.
- +Work intervals are hard but not maximal — sustainable effort across all 8 rounds.
- +During rest intervals, keep rowing lightly to maintain blood flow.
- +This format delivers 6 minutes of quality work — enough for a meaningful training stimulus.
- +Ideal for days when you only have 20-25 minutes but still want to train effectively.
