We got this question from a reader

I have been told that I can improve my erg scores if I did “conditioning style sessions” and “physical strength endurance” instead of the “cardio fitness endurance” which I do when I train to play tennis – which is my second favourite sport. Please could you explain the difference. Thank you.

While those terms are pretty vague and general in a training sense, I think I get the idea

I would believe that what they mean by “conditioning” and “Physical strength endurance” is weights (gym work) or resistance based training (i.e. bungees around the boat).

Rather than “Cardio Fitness” which you can think of a running, cycling, rowing, playing tennis.

In short I think people are trying to tell you that they think you are “fit enough” but lack the strength and power to improve your erg score.

Perhaps look for advice from a gym trainer (one with a back ground in rowing would be best)
