Flexibility plays a crucial role in determining your “biological age” and overall physical fitness. Dr. Syd Young, a physical therapist and owner at OutWellness, emphasizes that flexibility—particularly in the lower body—is associated with improved mobility, enhanced mental health, and reduced dependence on caregivers as you grow older. To explore this further, we consulted experts who provided insights into eight flexibility exercises that can make your body feel decades younger after hitting 40.

Even with an active lifestyle, aging often leads to a decline in mobility. This is due to the natural stiffening of joint capsules and tendons, coupled with changes in muscle, cartilage, collagen, and connective tissues, explains Dr. Amani Taylor, DPT, from FYZICAL Therapy & Balance Centers – Affton.

“As flexibility diminishes, maintaining the strength, balance, and endurance required for daily activities becomes more challenging,” Taylor notes. “This decrease can result in a loss of independence, a diminished quality of life, and an increased risk of hospitalization. Regular mobility exercises are essential for preserving joint health, ensuring a full range of motion, and supporting other aspects of physical movement.”

Mobility exercises soothe your joint tissues by boosting circulation and synovial fluid flow. “This prevents stiffness and promotes a healthy range of motion and recovery as we age,” Dr. Young explains.

Keep in mind that flexibility doesn’t simply mean being “fit.” Rather, “it’s about preserving your body’s ability to move freely, safely, and confidently as you age,” Dr. Young says.

Below, we have six flexibility moves that reveal whether your body’s decades younger. They provide essential insight into your strength, mobility, coordination, and balance.

Sit-And-Reach Test

“This classic test measures hamstring and lower back flexibility,” Dr. Young notes. “Limited range here is associated with greater risk of low back pain, impaired gait, and fall risk in older adults.”

1. Begin seated on the floor with your legs extended.
2. Reach your hands toward your toes.

Chair Sit-And-Reach

“A seated version of the sit-and-reach, this test is especially useful for older adults and can signal early mobility limitations or joint stiffness,” Dr. Young tells us.

1. Begin seated at the edge of a sturdy chair.
2. Extend one leg straight out in front of you, heel planted on the floor and toes pointing upward.
3. Keep the other foot flat on the ground.
4. Place one hand on top of the other as you extend your arms and reach forward toward the foot of your extended leg.
5. Maintain a straight back.
6. Repeat on the other side.

Back Scratch Test

“This shoulder mobility assessment reflects upper-body flexibility,” Dr. Young explains. “Limited motion can impact daily tasks like dressing and reaching. It’s a core part of senior fitness testing protocols.”

1. Stand tall, feet hip-width apart.
2. Reach one arm overhead, bend that elbow, and try to touch your upper back.
3. At the same time, reach your opposite arm up and behind your back, attempting to touch or overlap your fingertips.
4. Switch sides.

Deep Squat

“This move reflects ankle, hip, and spinal mobility,” Dr. Young points out. “If you can perform a controlled deep squat (heels down, chest up), it’s a strong marker of overall mobility and functional aging.”6254a4d1642c605c54bf1cab17d50f1e

1. Stand tall with your feet shoulder-width apart.

The Thomas Test

“If the resting leg lifts during this exercise, that indicates tightness in the hip flexors, which directly impact hip and lower back mobility,” Dr. Young says.

2. See how far you’re able to pull your knee toward your chest while the opposite leg stays rested.
3. Repeat on the other side.
