How much flexibility training do men over 40 actually need per week?

The minimum effective dose for maintaining flexibility and range of motion in men over 40 is 10–15 minutes of stretching per day (or 30–40 minutes twice per week of dedicated flexibility work), with each stretch held 30–60 seconds and performed after exercise or when muscles are warm, producing maintenance of existing range in adults over 40, with 2–4% range improvement per month possible with consistent training (Page, Int J Sports Phys Ther, 2012).

The qualification is that "maintenance" is the baseline. Without deliberate flexibility work, most men over 40 lose measurable range of motion at approximately 5–8% per decade. The 10–15 minutes daily is what stops that decline. Reverting lost range requires more, clinical experience suggests 30-minute daily mobility sessions for 8–12 weeks to significantly recover range in men who have not stretched in years. Daily practice matters more than session length: 10 minutes every day outperforms 60 minutes once per week for range of motion improvement.

Honesty Scale: Solid (1) for dose-frequency effects of flexibility training.

What to do: Set a daily 10-minute flexibility session (post-workout or before bed). Focus on the areas of most clinical relevance for men over 40: hip flexors, hamstrings, thoracic spine, and shoulder internal rotation. These four areas cover the majority of the postural and cardiovascular-adjacent flexibility limitations in this demographic.
