The opposing force encountered during the rowing stroke, created by a combination of water, air, or magnetic mechanisms within the machine, simulates the feel of propelling a boat through water. This simulated force varies depending on the chosen setting and the specific rowing machine model. For example, a water rower uses the viscosity of water, an air rower uses a fan’s rotation, and a magnetic rower employs magnetic fields to generate the opposing force. Each type provides a unique feel and level of adjustability.
This opposing force is crucial for an effective workout. It allows users to control the intensity of their exercise, contributing to muscle development, cardiovascular fitness, and overall strength. Historically, rowing machines with adjustable opposing forces were developed to enhance training for competitive rowers, providing a consistent and measurable training environment regardless of weather conditions. This development has since broadened access to effective rowing-based exercise for a wider audience.
