Longevity Basics

Movement & Function Assessment

A Core Component of the Sage Healthcare Longevity Exam

Your longevity depends on more than labs and vital signs — it depends on how well your body moves. During your 45-minute Longevity Exam, we complete a targeted, evidence-based movement and function assessment to measure strength, balance, mobility, posture, and real-life physical resilience. These abilities are among the strongest predictors of healthy aging, independence, and long-term vitality.

This assessment is quick, comfortable, and tailored to your current ability level.

What We Measure

1. Strength

We use grip strength testing, one of the most reliable markers of overall strength and healthy aging. Research shows it strongly predicts muscle health, cardiovascular risk, and future mobility.

2. Functional Mobility

The Sit-to-Stand Test and Timed Up-and-Go (TUG) measure lower-body strength, balance, and how efficiently you move through everyday activities such as getting out of a chair, turning, and walking.

3. Balance & Stability

We use validated balance tests — including single-leg stance and tandem stance — to identify early changes in neuromuscular control, fall risk, and gait stability.

4. Mobility & Flexibility

We assess thoracic rotation, hip mobility, and key movement patterns that influence posture, energy, and long-term joint health. These markers help identify stiffness, pain contributors, or compensations.

5. Posture & Gait

Your walking pattern tells a powerful story about how your body is aging. We evaluate step length, rhythm, posture, and weight transfer to detect early imbalance or movement inefficiency.

Why These Measurements Matter

These tests highlight far more than “fitness.” They identify early changes in:

• Muscle strength

• Metabolism and inflammation

• Balance and fall risk

• Joint mobility

• Neuromuscular coordination

• Postural patterns

• Functional aging

Better scores are linked to lower risk of chronic disease, improved energy, healthier metabolism, and better long-term independence.

What You’ll Learn

By the end of your Longevity Exam, you’ll know:

• Your current strength, balance, and mobility levels

• Which areas are aging faster — and which are strong

• The movement patterns contributing to pain, fatigue, or stiffness

• How your functional abilities compare to healthy norms

• A personalized plan to improve strength, mobility, posture, and daily performance

Your results feed directly into your Personalized 3-Month Longevity Roadmap, which includes exercises, mobility work, nutrition guidance, and lifestyle strategies built just for you.
