Science Reveals How Much Stretching You Need for Flexibility

Flexibility is a vital yet often overlooked component of fitness, especially as mobility declines with age. A recent study provides clear guidelines on how much stretching delivers results.

For immediate gains-like unlocking range of motion before a workout-four minutes of total stretching per muscle is optimal. These can be split into multiple sets, such as four one-minute stretches or eight 30-second holds. This temporary improvement enhances performance in activities requiring specific mobility, like squats or overhead lifts.

Long-term flexibility requires 10 minutes of cumulative stretching per muscle each week. This can be achieved through daily routines-for example, two minutes per session across five days. Warm-up stretches count toward this total if they target the same muscles consistently.

The study found no advantage to painful stretching: gentle tension is just as effective as intense effort. Experts recommend sustainable, comfortable stretches to encourage consistency and reduce injury risk.
