Laurel and Hardy, poppadoms and mango chutney, indoor rowing and sore bums: some things just seem made for each other. The question of suffering from a painful posterior when rowing for long periods is a trusty favorite of our mailbags, so we decided to try and settle it once and for all. To get to the, ahem, bottom of this, we went to the top and none other than Dick Dreissigacker, who along with his brother Pete started Concept 2 and developed the Indoor Rower. Dick's solution is simply this: bubble wrap, yup just your common or garden variety, although he also recommends the stuff with the small bubbles not the large ones. Simple but apparently effective.
