Flexibility is the range of motion at a joint, and keeping enough of it makes everyday movements easier: reaching a high shelf, turning to look behind you, putting on a sock, getting in and out of a car. MedlinePlus describes flexibility exercises as helping your joints move more easily.
The honest caveat: the U.S. guidelines say stretching works to increase flexibility, but the health benefits of flexibility work on its own aren’t known, and it’s unclear whether it lowers the risk of injury. So think of stretching as a way to keep moving comfortably, and keep walking and strength work as the main events.
Warm up first
The guidelines say warm-up and cool-down are an acceptable part of a physical activity plan, and that studies of effective exercise programs typically include them. A warm-up lets your heart rate and breathing rise gradually. A few minutes of easy walking, marching in place or arm circles is enough.
Stretching a cold muscle hard is where many people go wrong. The best time to stretch is after a walk or at the end of a strength session, when your muscles are warm.
How far, how long, how often
Unlike walking and strength work, the guidelines give no amount for stretching, so this is practical guidance from David Schutz’s original Fit after 50 course, not a researched protocol. Stretch to a point of mild tension, never to pain. Don’t bounce, and breathe normally. If you go too far you won’t be able to hold the stretch, and you risk a strain.
That course, citing the American College of Sports Medicine, suggests holding each stretch for 10 to 30 seconds. We have not independently checked that figure, so treat it as a comfortable range, not a rule. Skipping a day or two doesn’t undo your progress.
Most people feel tight in the same places: the hamstrings at the backs of the thighs, the hips after long periods of sitting, the calves and ankles, the shoulders and upper back, and the neck from looking down at phones and books.
A gentle ten-minute sequence
This is our own simple example, done seated or beside a sturdy counter. It is not a researched protocol and has not been reviewed by a clinician or physical therapist.
- Warm up for 2 to 3 minutesWalk around the room, or march in place holding a counter.
- Ankle circlesFive each way on each foot, seated.
- Seated hamstring reachSit tall at the edge of a chair, one heel forward, and lean gently until you feel mild tension. Hold and breathe, then switch.
- Shoulder rollsFive forward and five back.
- Seated trunk turnHands on opposite shoulders, turn gently to each side.
- Calf stretchAt a wall or counter, one foot back, heel down. Lean until you feel mild tension.
A short movement break and a comfortable walk give you the warm muscles stretching works best on.
Take a two-minute movement break
About 2 minutes · Very easy.
Stand up and keep moving for two minutes: walk around the room, reach your arms overhead, or do a few sit-to-stands.
Steps
- How to start
- The next time a show, a call, or a task ends, stand up and keep moving for two minutes.
- You will need
- Nothing. A little space to move.
- Done when
- You moved for about two minutes.
Who should ask a clinician first
MedlinePlus advises checking with a health care provider before starting, especially if you have trouble moving or balancing, or worry that exercise might not be safe. The original course adds a cautious list of times to ask before stretching: an unstable or very loose joint, a vascular condition, recent surgery, a recent strain, sprain or fracture, osteoporosis, pain when you move, or inflammation in a joint you’d be moving. It’s a list to ask about, not a diagnosis.
Your next step
Stretching works best as part of a routine that includes walking and strength.
