The benefits of rowing for runners and cyclists

As you walk into a gym at a peak busy hour, you will likely see the cardio equipment being heavily used, be it treadmills, elliptical, spinning bikes, recumbent bicycles, … All but one, the erg rower. Rowing machines (“ergs”) seat lonely most of the time, normally only used by rowers. Even a short peak of popularity thanks to House of Cards has not made ergs popular. Which is a pity, since for triathletes, cyclists and runners, the rowing machine is probably a great piece of equipment in the gym.

“Look at that red Tesla, it looks really nice, doesn’t it?” I said as we pulled out of the school parking lot after Hugo and Celeste’s after-school tennis lesson.


The Challenging Case of Training at Threshold

Our ability to be fast in racing, whether it is cycling or running, is limited by an almost magic upper ceiling. Right below this ceiling, we are able to push ourselves for a long time at a comfortable heart rate, as the body is able to bring fuel to the muscles and recycle toxins. But push above this ceiling, and things quickly fall apart. This limit is our lactate threshold, and although it is mainly determined by genetic factors and it can only be determined exactly in the lab, it is possible to train the body to raise this threshold. Training for threshold will allow sustaining more power for longer periods of time, and at a slightly higher heart rate that will then feel more comfortable.


Are lighter riders faster on Zwift?

In Real Life (IRL) cycling, the laws of physics apply and determine how fast we go. Do the same laws apply on Zwift, so that lighter riders go faster on the climbs on Zwift?
