We have been using a paddling machine this winter that Mike built for inside workouts. This paddling machine is for resistance training of the same muscle groups you would use in paddling a slalom or wildwater C-1 or C-2. It differs from most paddling machines in several ways. The first way it differs is that you move, not a flywheel. You have to drive the “boat’. You have to overcome inertia every stroke. It is a good tool for working on starts, sprints or reaccelerating the boat. Another way that it differs from paddling machine is it is quite high resistance. When set at the higher level, a set of 50 x 3 is a tough workout. We like the idea that the weight you are lifting (your body) is building the muscles that directly transfer to making the boat, on the water, go faster.
