Shawn Stevenson - Do These 3 Tests to Predict Your Lifespan (See How Long You’ll Live!)
The video introduces three simple fitness tests that can be done at home to assess one's fitness level and predict longevity. The first test is the gait speed test, which involves measuring how fast one can walk a 6-meter distance. Research shows that gait speed can predict life expectancy as accurately as other health indicators. Improving gait speed can be achieved by regular walking, aiming for at least 30 minutes or 8,000 steps daily, which also reduces risks of heart disease and diabetes. The second test is the single-leg balance test, which predicts survival in middle-aged and older individuals. Failing this test is associated with a higher risk of premature death. Practicing balance exercises and freeing the toes can improve performance. The third test is the sit-and-rise test, which assesses the ability to sit and rise from the floor without using hands. This ability is linked to lower mortality risk. Practicing sitting on the floor can enhance this skill. These tests help in maintaining functional fitness and should be shared with others, especially the elderly, to improve health and longevity.
Key Points:
- Gait speed test predicts life expectancy; aim for 2 meters/second or better.
- Walking 30 minutes daily reduces heart disease risk by 35% and diabetes by 40%.
- Single-leg balance test failure doubles risk of premature death; practice balance exercises.
- Sit-and-rise test predicts mortality; practice sitting on the floor to improve.
- Use wide toe box shoes and toe separators to improve foot health and balance.

1. 🏋️ Introduction: Fitness Tests for Longevity
- There are three fitness tests that determine if your body is fit enough for a longer lifespan.
- All three tests are backed by science and can be performed at home or outside.
- The segment will cover the science behind each test, instructions on how to perform them, and methods to improve performance.
- The goal is to ensure functional fitness for a longer lifespan.
2. 🚶 Test 1: Gate Speed - Predicting Longevity
- A meta-analysis published in the Journal of the American Medical Association found that walking speed, measured down to the tenth of a meter per second, is a predictor of life expectancy for older adults.
- Walking speed, along with age and gender, can predict life expectancy as accurately as a comprehensive set of health indicators such as blood pressure, BMI, and chronic health conditions.
- Instead of complex health assessments, a simple test timing an older person walking a few meters can accurately predict if they might live an extra 5 to 10 years or more.
- The test is based on a 6-meter gate assessment, providing a practical and efficient method for estimating longevity.
3. ✨ Enhancing Gate Speed for Life Extension
- Measure a 6-meter flat stretch and use cones or markers to designate the start and end.
- Use a stopwatch to time your walking speed over this distance, ensuring you start timing only once you reach the 6m mark.
- Calculate gate speed by dividing 6 meters by your time in seconds; a speed of 2 m/s or better is excellent.
- Conduct the test at least twice to obtain an accurate average.
- Gate speed is an indicator of longevity, influenced by factors such as body weight, blood flow, muscle function, and brain health.
- Maintain or improve gate speed throughout life to avoid degradation with age.
- Being proactive and intentional about training can help preserve gate speed.
- Incorporate exercises such as strength training, balance drills, and cardiovascular workouts to maintain or improve gate speed.
- Track progress periodically and adjust training routines as necessary to maintain optimal speed.
4. 👣 Foundation of Mobility: Foot Health
- Regular walking, at least 30 minutes daily, can reduce heart disease and stroke risk by 35% and type 2 diabetes risk by 40%, per the American Heart Foundation.
- Walking is considered a 'wonder drug' due to its broad health benefits, including hormone regulation.
- Research in Endocrinology highlights a link between testosterone levels and daily steps, with levels notably increasing at 8,000 steps or more.
- To enhance gait and foot health, aim for daily goals of either a 30-minute walk or 8,000 steps.
- Incorporate foot-strengthening exercises such as toe curls and heel raises to further improve foot health and support mobility.
5. 🦵 Test 2: Single Leg Balance - Stability and Survival
- Healthy feet are crucial for improving walking mechanics as they are the foundation of the kinetic chain, which involves muscles, joints, nerves, and fascia.
- Feet contain 26 bones, 33 joints, 19 muscles, 107 ligaments, and over 200,000 nerve endings, making them vital for movement data collection.
- Wearing narrow shoes can mute nerve function, leading to dysfunction throughout the body, emphasizing the importance of proper footwear.
- Rehabilitation involves wearing shoes with a wider toe box and individual toe compartments to enhance physical literacy and fitness.
- Foot health is linked to longevity, exemplified by Mark Sisson, founder of Pala, who maintains high fitness levels at over 70 years old.
- Rehabilitation shoes, such as Palas, provide metabolic benefits and improve foot functionality, leading to better health and performance.
6. 🚶♂️ Walking: A Key to Balance and Longevity
- Backward walking training significantly improved walking speed and balance in stroke patients more than standard balance training after just one month, indicating its potential as a rehabilitation tool.
- Incorporating backward walking into regular exercise routines can serve as an effective preventative measure against future fall incidents and enhance overall stability.
- Engaging in full-body movement and maintaining a natural walking gait is essential for maximizing the efficiency of walking exercises.
- Adding resistance, such as a weighted vest or backpack, to walking routines can increase the intensity and effectiveness of the workout, potentially leading to greater health benefits.
7. 🧘♂️ Test 3: Sit and Rise - Functional Movement
- A study in the British Journal of Sports Medicine found that inability to stand on one leg for 10 seconds in middle and later life doubles the risk of premature death.
- Researchers evaluated 1,700 people aged 51 to 75, all free of walking problems, and followed them for 7 years, assessing their balance and correlating it with mortality.
- Failing the single leg balance test was associated with an 84% higher risk of dying within the study period, highlighting the critical role of balance in longevity.
- Balance ability impacts fall prevention, the ability to catch oneself when stumbling, and falling gracefully with minimal injury, which are crucial for maintaining independence in later life.
- Balance expresses the strength and resilience of muscles, bones, and connective tissues, providing stability against impact forces and preventing injuries.
8. 🧩 Mastering Balance: Tips and Techniques
- Begin mastering balance by choosing a leg to balance on; for instance, start with the left leg, keeping arms at your sides without support.
- Place the top of the opposite foot onto the calf of the standing leg, maintaining this position for 10 seconds before switching legs.
- If balance is difficult, practice frequently to train the nervous system to adapt to one-leg standing, enhancing stability over time.
- Incorporate single-leg balance exercises such as single leg Romanian Deadlifts (RDLs) to further develop balance skills.
- Progress to advanced techniques, including lateral bounding or hopping from one leg to another, and single-leg jumps using a jump rope.
- For those at an advanced fitness level, employing a heavy rope for single-leg movements can significantly boost balance capabilities.
9. 🦶 Toe Freedom: The Secret to Balance
- A 2009 study found that constraining the big toe deteriorates balance performance, particularly in single leg stance and directional control during weight shifting, highlighting the importance of toe freedom for balance.
- Simply switching to a shoe with a wide toe box does not automatically restore natural toe splay; toes are trained to stay together over time, indicating the need for active measures to regain toe mobility.
- A randomized control trial showed significant improvements in bunion condition and pain for participants using toe separators in addition to shoes with wider toe boxes, demonstrating the efficacy of toe separators.
- Improving single leg balance can be achieved by walking and spending more time barefoot, as these activities inherently help improve balance and foot intelligence.
- Wearing shoes with individual toe boxes or using toe socks can aid in maintaining toe separation and proprioception, contributing to better balance.
- Spending more time barefoot at home allows for natural toe splay and can significantly enhance foot intelligence and balance, providing a practical strategy for improving foot health.
10. 💪 Conclusion: Movement as Medicine for Longevity
- The sit and rise test is a significant predictor of mortality for individuals aged 51 to 80, with each unit increase in test score leading to a 21% improvement in survivability.
- Sitting on the ground engages multiple aspects of mobility, including muscles, tendons, and ligaments, providing important data inputs for how we move and sit.
- The test involves moving from standing to sitting on the floor without using hands, which can be practiced for improvement by increasing time spent sitting on the floor.
- Adopting floor sitting habits can enhance mobility and functionality, allowing individuals to engage in daily activities like watching TV or reading while improving fitness.
