The common answer is 30 seconds, which is roughly right and also incomplete. Hold duration matters less than total weekly time under stretch, and both matter less than whether you are stretching before or after training. Here are the numbers the research actually supports.

Thirty Seconds Is the Floor, Not the Target

Holds under 15 seconds produce almost no lasting change in range of motion. Somewhere between 20 and 30 seconds the nervous system stops resisting and the tissue begins to lengthen, which is why 30 seconds became the standard recommendation.

Going longer helps, but with diminishing returns. A 60 second hold outperforms a 30 second hold modestly. A 120 second hold is not meaningfully better than 60. For most people 30 to 60 seconds per position is the productive range, and anything past two minutes is time spent for very little additional return.

Older adults are the exception worth noting. Connective tissue stiffens with age, and holds of 60 seconds produce noticeably better results than 30 past roughly age 60.

Weekly Volume Is the Number That Matters

Individual hold length gets all the attention, but cumulative time under stretch predicts range-of-motion gains far better.

Goal Per Muscle Weekly Practical Schedule
Maintain range 2 to 3 min 2 sessions, 1 hold each
Improve range 5 to 10 min 4 sessions, 2 holds each
Significant change 10 min plus Daily, 2 to 3 holds

Ten minutes per week per muscle group sounds like a lot until you break it down: two 60 second holds, five days a week. Three days of stretching one muscle for 30 seconds totals 90 seconds weekly, which explains why so many people stretch consistently and see nothing change.

Two Rounds Beat One Long Hold

Splitting your time works better than consolidating it. Two 45 second holds with a 20 second break produce more range than one 90 second hold, because the second round starts from the position the first one earned.

Stop when the stretch stops fading. If you are 40 seconds in and tension has plateaued, holding another minute accomplishes nothing. The sensation dropping off is the signal that the position did its work, and this pattern applies across the cool-down stretching routine after strength training.

Timing Changes the Correct Duration

Before training, static holds over 60 seconds temporarily reduce force output by a measurable amount. This is real but frequently overstated. The effect fades within 10 minutes and matters mainly for maximal attempts, not for a normal session.

Still, the simple rule holds: dynamic movement before training, static holds after. Pre-workout, use leg swings and controlled range work for 5 to 8 minutes. Post-workout, when tissue is warm, is when 30 to 60 second static holds do their best work. Hip-specific timing is covered in this guide on post-squat mobility work for tight hips, and hamstring positioning in these stretches for tight hamstrings after leg day.

Stretching Does Not Do What Most People Expect

Here is the honest part. Stretching does not prevent soreness, and the evidence on this is fairly clear. If you stretch for 12 minutes after a heavy squat session expecting to feel fine tomorrow, you will be disappointed.

It also does not meaningfully reduce injury risk in most sports, and it does not flush lactic acid, which cleared on its own within an hour of finishing regardless. What stretching reliably does is increase range of motion, which is a legitimate goal on its own and not the same as recovery. Soreness responds better to the approaches covered in this guide on preventing muscle soreness after a gym home workout, and to eating enough, which this breakdown of what to eat after a strength training session handles.

You Probably Need Less Than You Think

The second honest point. If your squat depth is fine, your deadlift setup is clean, and you can reach overhead without your ribs flaring, you have adequate range. Chasing more is optional.

Extreme flexibility is a specialized goal for gymnasts and dancers, not a general fitness requirement. A moderate amount of passive stiffness actually improves force transfer during heavy hinging and sprinting, which is why strong lifters are rarely flexible and are not being held back by it. Spend your 10 weekly minutes on the one or two positions that limit a movement you care about, and ignore the rest.

Hold for 30 to 60 seconds, do two rounds, stretch after training rather than before, and track weekly minutes instead of individual sessions. The rest of the recovery phase guides cover what stretching does not handle.
