The curved treadmill is a new model of treadmill that is depopulating in all gyms worldwide. Its features are revolutionary, and it does not require electricity to work. The curved tread surface offers a different experience from a traditional motorized treadmill.

The self-powered treadmill allows you to run naturally as if you were running outdoors on your legs. But one particularity of this curved treadmill or treadmill (for lovers of the English language) has captured athletes from all over the world.

The type of movement performed to run on this particular curved treadmill uses more muscle groups in the body simultaneously than many athletes’ traditional way of running.

Indeed, the curved section’s particular conformation encourages using not so much the heel but the front part of the foot and allowing the use of a whole series of muscular portions that are stimulated simultaneously and effectively.

A unique tool to train different domains.

The natural conformation of this type of tool offers the possibility of training and improving several skills at the same time, including:

  • Cardiorespiratory endurance
  • Muscle endurance
  • Speed
  • Coordination
  • Power
  • Equilibrium
Running MechanicsCurved treadmills can promote a more natural running experience by encouraging a proper foot strike and better running form, which may potentially reduce the risk of injury.Gottschall, J. S., & Kram, R. (2005). Ground reaction forces during downhill and uphill running. Journal of Biomechanics, 38(3), 445-452.  
Energy ExpenditureCurved treadmills can increase energy expenditure and heart rate compared to motorized treadmills at the same speed, potentially leading to greater calorie burning and cardiovascular benefits during workouts.Alcaraz, P. E., Carlos-Vivas, J., Oponjuru, B. O., & Martínez-Rodríguez, A. (2018). The effectiveness of a curved non-motorized treadmill on running performance in national-level male and female middle-distance runners. Biology of Sport, 35(1), 87-93.  
Workout RecommendationsIntegrating curved treadmill workouts into your training routine can help improve running mechanics, increase energy expenditure, and provide a more engaging workout experience. Consider incorporating interval training or longer steady-state sessions on a curved treadmill.General advice based on the benefits of curved treadmills; no specific scientific journal references available.

Why should you consider using a curved treadmill?

A curved treadmill offers many advantages in terms of performance enhancement. The first is undoubtedly the use and stimulation of various muscle groups during the exercise and the more significant energy expenditure compared to a classic motorized treadmill.

Thanks to the propulsion technique required to advance the running belt (similar to natural running), the curved treadmill naturally recruits more muscles, including buttocks and knee tendons, for its running. By minimizing the vertical displacement of the centre of mass, there is a simultaneous increase in energy expenditure.

The curved treadmill design encourages forefoot running, reducing the impact on joints and improving performance. Thanks to this adjustment, the core and trunk are more involved due to the need to run with an ergonomically correct angle.

The average calorie consumption with a treadmill like this has been shown to be 30% higher! (compared to a classic motorized treadmill)

Why should you consider adding a curved treadmill to your gym?

There are several reasons why a gym should consider adding a curved treadmill to its cardio enhancement area. Some of the advantages include the following:

  • Safer than traditional motorized treadmills.
  • Less friction and no heat generation due to the interaction between the belt and transport systems.
  • The running surface fundamentally differs from the sliding belts on traditional treadmills, where cotton-nylon belts are normally used.
  • No electrical power is needed.
  • Environmentally friendly.
  • Longer duration than a traditional treadmill because there are no motorized parts.
  • Maintenance costs are reduced to a minimum.
  • Efficiency in training several domains at the same time.

How to train with the curved treadmill?

Curved treadmills can be used in the same way as traditional treadmills. Even with this new treadmill, you can perform any exercise, from sprint intervals, for example, to slow running progress. But there are substantial differences in the types of results obtained.

There are three main types of training in which the curved treadmill gives the best of itself, and they are :

Training for the sprint

Sprint intervals are an ideal workout because there is no motor. This means that the athlete can start their sprint interval very quickly without having to wait for the motor on the classic treadmill to rotate the belt at a certain speed before being able to shoot.

High-Intensity Interval Training (HIIT)

With a curved treadmill, you can adjust your pace autonomously by increasing your pace to simulate road running or interval running. Because it has no speed limits, the curved treadmill is a great choice for elite-level athletes, where the pace required is faster than the top speed of any commercial motorized treadmill to date.

Cardiovascular Endurance Training

Thanks to the revolutionary traction method, it offers greater resistance than a classic treadmill. The type of posture used during the exercises exponentially conditions the cardiocirculatory capacity and always offers effective training, which resists guaranteed results over time.

The curved treadmill has created a true revolution in the fitness world. Training with such a tool means trying a unique experience that is closer than ever to running naturally. The lack of motor and drive belt conformation ranks this conditioning system among the best in the world for improving a whole host of skills across multiple domains.
