A longer UT2 session designed to extend aerobic capacity. Forty-five minutes at a controlled heart rate develops the cardiovascular system and teaches the body to burn fat efficiently. This is the session that separates good rowers from great ones.

Coaching Notes
- +UT2 means Utilisation Training Zone 2 — the aerobic base-building zone.
- +Cap your stroke rate at 20 spm. If you need to go faster, lengthen the stroke rather than increasing rate.
- +Heart rate drift of 5-10 bpm over 45 minutes is normal — do not chase the split down to compensate.
- +Stay hydrated. Have water within reach and sip every 10-15 minutes.
- +If this feels too easy, you are doing it right. The adaptations happen at low intensity over time.
