Whipr is a lightweight Ergometer designed for regular home use and heavy workload, but it is not intended for commercial use. The base unit will handle strenuous regular loading of up to 850Kn.
Our rower is suitable for everyday endurance workouts. At it's maximum setting the resistance is equivalent to a full sized rower on a mid to high damper setting (around a 6 or 7 on Concept2). The rower is not suitable for competitive use and the software supports a maximum sustained 500m split time of 1:35.
In short, if you plan to row a marathon or smash calories as quickly as possible in a timed crossfit workout, we'd recommend opting for a commercial grade rower. For regular, light to hard workouts whipr is an excellent choice.
