A 2019 study found that seated ellipticals can help reduce sedentary behavior in older adults. Another study involving this population found that using these devices while performing seated activities increased energy expenditure.

Research also suggests that compact elliptical devices can help increase energy expenditure in adults ages 25–65 years.

This form of exercise may also be more effective than cycling for gait training and rehabilitation.

According to the Centers for Disease Prevention and Control (CDC), only 1 in 4 adults in the U.S. reaches the recommended daily physical activity levels. About 31 million adults ages 50 years and over do not exercise at all.

In a 2018 research paper, the CDC also reported that inadequate physical activity was a causative factor in 8.3% of deaths in the U.S. Low physical activity can contribute to heart disease, obesity, type 2 diabetes, and certain types of cancer.

According to the Physical Activity Guidelines for Americans, regular moderate-to-vigorous physical activity can benefit both physical and mental health by:

Below we answer common questions about Cubii:

Who is the Cubii for?

People who may benefit the most from using a Cubii device are those who sit for long periods or do not have time to exercise. For example, people who work desk jobs or wish to exercise while sitting.

What muscles does Cubii work?

According to the designers, the Cubii exercises the glutes, quadriceps, and hip flexors when pedaling forward and the hamstrings and calves when peddling backward.

If maintaining a proper upright seated position when operating the device, the Cubii may work on the core and lower back muscles.

Does the Cubii work?

The operation of a Cubii mini elliptical burns around 150 calories per hour.

However, using a Cubii device does not require the user’s full attention, as they can perform other activities while seated, such as working at a desk or reading.

Can you lose weight with Cubii?

Cubii elliptical machines can help a person lose weight. However, doctors or fitness trainers may also advise doing other exercises rather than depending on the Cubii device.

Cubii sells a range of seated elliptical machines that can fit under desks or in front of chairs. They are portable and run quietly while providing a gentle workout for the legs.

Regular physical activity significantly reduces the negative health effects of a sedentary lifestyle. Cubii under-desk ellipticals offer people of all ages, abilities, and lifestyles a way to be physically active while they work or perform other everyday activities.
