Increases calorie burn: Curved manual treadmills require users to exert more effort for movement. Research by McNulty et al. (2019) found that exercising on a curved treadmill resulted in a 30% higher calorie burn compared to traditional flat treadmills due to the self-powered nature of the machine and the work needed to maintain speed.
Adjustable intensity levels: The speed on a curved manual treadmill is determined by the user’s effort. This allows for customized workouts. Users can control the difficulty by simply adjusting their pace. A study published in the Journal of Sports Science (Smith et al., 2021) showed that such flexibility leads to enhanced cardiovascular fitness and improved endurance.
Engages more muscle groups: The design activates more muscle groups, including the glutes, hamstrings, and calves. This multidimensional engagement helps in building strength and toning muscles effectively, as highlighted in a study by Lee et al. (2018) that focused on muscle engagement during treadmill workouts.
Low impact on joints: The curved nature helps in softening impacts during workouts, which can minimize stress on the joints. This aspect is important for individuals recovering from injuries or those with joint concerns, making workouts safer and more effective.
