Can an incredibly stiff person become flexible?

Yes, absolutely. While genetics play a role in baseline connective tissue elasticity, even the stiffest individuals can improve flexibility significantly through consistent, proper training. The nervous system can be retrained to allow greater range of motion at any age.

Which is better, walking or stretching?

They serve different physiological purposes and should not be compared as “better”. Walking builds cardiovascular health and endurance, while stretching improves joint range of motion and muscle elasticity. For a complete health profile, you need both – one isn’t a substitute for the other.

Which muscles should I stretch daily?

Focus on the muscles that are chronically shortened by daily activities – typically the hip flexors, hamstrings, pectorals (chest), and upper trapezius (neck/shoulders). Daily gentle mobilization of the spine is also highly recommended to counteract sitting.

Which muscle can you not stretch?

Technically, you can’t stretch a muscle that doesn’t cross a joint, but practically, you should avoid aggressively stretching muscles that are already over-lengthened or acting as protective stabilizers. For example, stretching the lower-back muscles when the actual cause of tightness is weak glutes and tight hip flexors can destabilize the spine.

Why shouldn't you stretch in the morning?

You can stretch in the morning, but you should avoid intense, end-range static stretching immediately after waking without a warm-up. Your body temperature is low ( 18 ), and your spinal discs are fully hydrated and pressurized ( 19 ), which makes them more vulnerable to injury during extreme flexion or twisting movements.
