Let the easy row finish easy
I see so many people thinking they have to finish a session by pushing hard, regardless of what the session aim was. I think some of that is a misunderstanding of what an easy session is for. And there's ego getting in the way.
An easy session, if the programme is set up correctly, has a point. If you start it and then decide you're going to push hard at the end because you feel good, you're saying you know better than the programme. You need to prove to yourself that you can push harder.
Have an honest look at why you're trying to push harder even though your programme says this is a low-intensity session. Leave the intensity to another session. Finish this one at that low intensity.
If you finish feeling fresh and able to do more, wait until your high-intensity session to do it. You don't need to adjust the easy row by randomly throwing in some hard work at the end.
Sometimes it's chasing a round number. You've only got another kilometre and you could round it up to something that feels good. But say the session was 45 minutes. You could push harder for two or three more minutes and round the distance off, but that's giving you more fatigue and burning more energy for no specific benefit.
The session was 45 minutes. Finish there.
When your programme is written, there should be thought behind the sessions. It's not just thrown together bit by bit. If you need help with the programme to be able to trust it, that's worth getting help with.
