Yes, you can regain flexibility after 40. Muscles and connective tissue still adapt to regular stretching and to strength training done through a full range of motion. Most men notice they feel looser within 2 to 4 weeks, and measurable gains in range typically build over 8 to 12 weeks of training most days. You may not get back the range you had at 18, but you can get back what daily life and lifting require.
Why flexibility fades after 40
Flexibility doesn’t disappear because of a birthday. It fades mostly because of what you stop doing:
- You stop using the end of your range. Years of sitting mean your hips rarely fully extend and your shoulders rarely reach overhead. Tissues adapt to the ranges you use.
- Your nervous system protects unfamiliar positions. Much of what feels like “tight” is your body limiting a range it hasn’t practised. With repetition, that tolerance grows.
- Tissues do change somewhat with age. Connective tissue becomes a little stiffer, which is one reason progress is steady rather than fast.
- Old injuries leave restrictions. A sprained ankle from 20 years ago can still limit how far your knee travels over your toes.
The first two are highly reversible. That’s why most men regain more than they expect.
Stretching or strength training?
Both work. A meta-analysis of 11 studies found no difference in range-of-motion gains between strength training and stretching (Afonso et al., 2021). The practical difference:
| Approach | Strength | Weakness |
|---|---|---|
| Static stretching | Simple, can be done anywhere, good for a specific tight spot | Builds no strength in the new range |
| Full-range strength training | Builds range and strength together | Needs equipment and good technique |
| Both | Best of each | Takes slightly more time |
For a busy man over 40, the efficient answer is to lift through full ranges (deep goblet squats, Romanian deadlifts to a long hamstring stretch, full-range pulldowns) and add short, targeted stretching for the one or two areas that hold you back.
One caution on timing: long static stretches right before power or skill work may slightly reduce performance. A review of golf warm-ups, for example, found dynamic and resistance-based warm-ups improved performance measures, while static stretching was inferior and potentially detrimental (Ehlert & Wilson, 2019). Save long holds for after training or a separate time.
How long it takes to regain flexibility
| Time | What usually happens |
|---|---|
| First session | A small, temporary improvement that fades within hours |
| Weeks 2–4 | Positions feel less uncomfortable; you sink deeper with less effort |
| Weeks 6–12 | Measurable, lasting gains in range if you’ve practised most days |
| 6 months+ | New range feels normal; maintain with a few sessions a week |
Consistency beats intensity. Ten minutes most days does more than one hour on Sunday.
A simple plan for the four areas men lose most
Do this 5 to 6 days a week, about 10 minutes. Hold each stretch for 30 to 60 seconds, breathing slowly. It should feel like a strong stretch, never pain.
| Area | Stretch | Dose |
|---|---|---|
| Hamstrings | Lying hamstring stretch with a strap | 2 × 45 s per side |
| Hip flexors | Half-kneeling hip flexor stretch, glute squeezed | 2 × 45 s per side |
| Chest and shoulders | Doorway pec stretch, then arms overhead against a wall | 2 × 30 s each |
| Calves and ankles | Wall calf stretch, straight and bent knee | 2 × 30 s each |
Add one strength move per area in your lifting sessions: Romanian deadlift, split squat with an upright torso, overhead press through a full range, and slow calf raises from a deep stretch.
For drills that build control in the new range, rather than just passive stretch, see mobility exercises for men over 40. If your desk job is the main culprit, the posture guide for men in their 40s covers movement breaks, which Canada’s guidelines also recommend for breaking up long sitting periods (CSEP).
Tracking your progress
Pick two simple tests and repeat them every four weeks:
- Toe touch: standing, knees straight, how far do your fingertips reach (shins, ankles, floor)?
- Overhead wall test: back against a wall, can your thumbs touch the wall above your head without your lower back arching off it?
- Deep squat: can you sit into a bodyweight squat with heels down and hold for 30 seconds?
Write down the result, or take a phone photo from the side.
When stiffness needs a professional
See a doctor or physiotherapist if stiffness comes with joint swelling, redness, pain at night, morning stiffness that lasts well over an hour, numbness or tingling, or if one joint is losing range quickly. Those signs need a diagnosis, not a stretching routine.
The bottom line
Flexibility after 40 comes back with practice. Stretch the areas that limit you most days, lift through full ranges, and give it 8 to 12 weeks before you judge it. If you want a coach to find the restrictions that actually affect your training and build the fixes into your sessions, weekly 1:1 coaching starts from $99 a week. A ready-made daily routine is in the mobility routine for men over 40.
Questions people also ask
Is it too late to become flexible at 50?
No. Range of motion responds to training at any age. You may never do the splits, but most men in their 50s can comfortably regain enough range to squat deeply, touch their toes and reach overhead.
How often should I stretch to improve flexibility?
Most days is best for a stubborn area, even if only 5 to 10 minutes. Two or three dedicated sessions a week also works if you're consistent.
Why am I so stiff in the morning?
Tissues stiffen after hours of lying still, and morning stiffness is common with age. It usually eases with gentle movement. Stiffness that lasts more than about an hour, or comes with swelling, is worth mentioning to your doctor.
Does lifting weights make you less flexible?
Not if you lift through a full range of motion. A meta-analysis found strength training improved range of motion about as much as stretching. Partial-range lifting is the habit that limits flexibility.
