Why Walking 10,000 Steps a Day is Still the Best Cardio

Walking 10,000 steps daily has been popularised as a benchmark for health and fitness, but does it truly stand as the best form of cardiovascular exercise? Despite the rise of high-intensity interval training (HIIT), cycling, and other workout methods, walking retains its status as an accessible, effective, and scientifically backed form of cardio.

This article explores why walking 10,000 steps a day remains unmatched in its benefits, supported by evidence-based research.

The Origin of the 10,000 Steps Goal

The concept of walking 10,000 steps originated in Japan during the 1960s. Dr Yoshiro Hatano, a Japanese researcher, sought to determine the optimal level of daily activity to maintain health. His studies found that burning approximately 300 calories through walking could significantly reduce the risk of various diseases (Hatano, 1993).

This calorie expenditure translates roughly to 10,000 steps for most people, depending on stride length and walking pace. This target was subsequently marketed as part of Japan’s pedometer campaign and later gained worldwide recognition.

Cardiovascular Benefits of Walking

Walking provides substantial benefits for cardiovascular health. Regular walking reduces blood pressure, improves circulation, and strengthens the heart muscle. A study by Harvard Medical School found that walking for just 2.5 hours per week lowered the risk of cardiovascular disease by 30% in women (Lee et al., 2001).

Additionally, walking helps to maintain healthy cholesterol levels by increasing HDL cholesterol and decreasing LDL cholesterol, thereby reducing arterial plaque build-up (Murtagh et al., 2015).

Moreover, walking improves endothelial function, which is crucial for vascular health. Poor endothelial function has been linked to an increased risk of atherosclerosis and other cardiovascular diseases. A 2020 study in the journal Circulation demonstrated that moderate-intensity walking significantly improved endothelial function compared to sedentary behaviour (Madden & Ball, 2020).

Weight Management and Caloric Burn

Walking is a practical and sustainable method for weight management. While it might not burn as many calories per hour as running or cycling, walking is easier to incorporate consistently into daily routines. On average, walking 10,000 steps burns approximately 400–500 calories, depending on an individual’s body weight and walking pace (Bassett et al., 2010). This calorie burn contributes to a calorie deficit, aiding in weight loss or maintenance when paired with proper nutrition.

Additionally, walking enhances fat oxidation. A study published in Obesity showed that walking at a moderate pace promotes the utilisation of stored fat for energy, making it effective for long-term fat loss (Miyashita et al., 2013).

Mental Health and Cognitive Benefits

Beyond physical health, walking profoundly impacts mental well-being. Regular walking is associated with reduced levels of anxiety, depression, and stress. A meta-analysis published in Health Promotion International found that walking interventions significantly improved mental health outcomes, particularly when done outdoors in nature (Kelly et al., 2018).

Walking also enhances cognitive function. Research from the University of Illinois revealed that older adults who walked regularly demonstrated improved memory, attention, and executive function compared to sedentary individuals (Erickson et al., 2011). This is attributed to increased blood flow to the brain and the release of brain-derived neurotrophic factor (BDNF), which supports neural health and plasticity.

Joint and Musculoskeletal Health

Walking is a low-impact exercise, making it ideal for people with joint issues or those who cannot engage in high-impact activities. Unlike running, which exerts significant stress on the knees and hips, walking reduces the risk of joint wear and tear while still stimulating the muscles, bones, and cartilage. A study published in Arthritis & Rheumatology found that individuals who walked more had a lower risk of developing osteoarthritis-related disabilities (Lo et al., 2015).

Furthermore, walking enhances bone density and reduces the risk of osteoporosis. Weight-bearing exercises, including walking, stimulate bone remodelling and maintain skeletal strength, particularly in postmenopausal women who are at a higher risk of osteoporosis (Gregg et al., 2000).

Walking and Longevity

Walking 10,000 steps daily is strongly linked to increased life expectancy. A 2019 study in JAMA Internal Medicine found that older women who averaged 7,500 steps per day experienced a 40% reduction in mortality risk compared to those with lower step counts. The benefit plateaued at around 10,000 steps, suggesting that this number maximises health benefits without overexertion (Lee et al., 2019).

Regular walking also mitigates the risk of chronic diseases such as type 2 diabetes, hypertension, and certain types of cancer. The American Diabetes Association highlights that walking improves insulin sensitivity, helping to regulate blood glucose levels and prevent diabetes onset (Colberg et al., 2010).

Accessibility and Sustainability

One of the most significant advantages of walking is its accessibility. Unlike gym memberships or specialised equipment, walking requires no financial investment or expertise. It can be done anywhere and tailored to suit individual fitness levels. This makes it an inclusive exercise option for people of all ages, fitness levels, and socio-economic backgrounds.

Additionally, walking is sustainable in the long term. Many people struggle to adhere to high-intensity workout routines due to time constraints, physical limitations, or burnout. Walking, however, is easy to integrate into daily life—whether through commuting, taking the stairs, or walking during breaks.

Comparing Walking to Other Forms of Cardio

While high-intensity exercises like running or cycling may burn more calories in less time, walking has unique advantages. First, walking has a lower injury risk due to its low-impact nature. Runners, for example, face a higher likelihood of shin splints, stress fractures, and knee injuries (van Gent et al., 2007).

Second, walking is less intimidating for beginners. People new to exercise may find high-intensity workouts overwhelming, leading to inconsistent participation. Walking provides a manageable starting point, fostering adherence and long-term habit formation.

Lastly, walking allows for multitasking. People can listen to podcasts, make phone calls, or even practise mindfulness while walking, making it more appealing for individuals with busy schedules.

Practical Tips to Reach 10,000 Steps

1. Break It Down: Divide the goal into manageable chunks, such as three 20-minute walks throughout the day.
2. Incorporate It Into Your Routine: Opt for walking meetings, park farther away from entrances, or take the stairs instead of lifts.
3. Use Technology: Fitness trackers and step-counting apps can help monitor progress and keep you motivated.
4. Walk with Friends or Pets: Social walks or dog walking can make the experience enjoyable while keeping you active.
5. Set Reminders: Use phone alarms to prompt short walking breaks during sedentary periods.
