Five minutes is not a compromise
It sounds like the version you settle for. The evidence suggests it is close to the version that works.
A 2025 meta-analysis in Sports Medicine pooled 189 studies and 6,654 adults to find the dose that improves flexibility. It found that gains within a single session flattened at roughly four minutes per muscle group, and that weekly gains flattened at about ten minutes per muscle group with no advantage to any particular way of splitting them up. It also found thirty-second holds matching sixty-second ones.
So a five-minute session spread across a few areas is not a shortened version of a better routine. It is roughly where one session stops adding much.
What fits in five minutes
| Hold length | Stretches that fit | Both-sides stretches that fit |
|---|---|---|
| 30 seconds | 10 | 5 |
| 40 seconds | 7 | 3 or 4 |
| 45 seconds | 6 | 3 |
Both-sides stretches cost double. A sequence of six stretches where four need both sides is a ten-hold routine, which is where most of Lucy's five-minute routines land.
The sequence, written out
This is Unstick Your Neck, the five-minute routine in Lucy that needs no floor. It is written out here so you can do it without downloading anything.
- Chin Tuck, 20 seconds. Slide your head backwards over your shoulders, like making a double chin deliberately.
- Neck Side Bend, 30 seconds each side. Drop one ear towards the shoulder. Let the weight of your head do it.
- Upper Trapezius Stretch, 30 seconds each side. As above, with the opposite arm reaching down and slightly back, palm facing away.
- Levator Scapulae Stretch, 30 seconds each side. Turn your head forty-five degrees away, then look down towards your armpit.
- Neck Rotation, 20 seconds each side. Turn slowly to look over one shoulder.
- Shoulder Roll, 20 seconds. Big slow circles backwards.
- Cross-Body Shoulder Stretch, 30 seconds each side. Draw one arm across the chest with the other forearm.
- Chest Opener, 20 seconds. Hands clasped behind, shoulder blades together.
- Wrist Circles, 30 seconds. Slowly, both directions.
- Wrist Flexor Stretch, 30 seconds each side. Arm out, palm up, gently draw the fingers back.
Nothing in it needs a mat, a floor or a change of clothes.
Why a timer changes the odds
Counting seconds yourself is the part that quietly ruins a routine. You either rush, or you lose track, or you watch the clock instead of the stretch.
More specifically: a routine with both-sides stretches needs you to remember which side you are on while also holding a position. That is the job an app is genuinely better at than you are.
Lucy's timer counts each hold and says when to switch sides, out loud, so you can shut your eyes. Every duration can be shortened before you start and it remembers what you chose.
Doing it more than once a day
The research found no penalty for frequency, so twice is fine. Two five-minute sessions a day across a working week is roughly fifty minutes, which comfortably clears the weekly threshold for the areas involved.
What it is not worth doing is turning five minutes into twenty in the hope of getting there faster. That is where the evidence is clearest: beyond about four minutes per muscle group in one sitting, more time added nothing measurable.
When to stop, and when to ask someone
Stretching is general fitness, not treatment. Stop anything that produces pain, dizziness, numbness or anything that feels wrong. Discomfort and pain are not the same thing, and only you can judge the difference from the inside.
Talk to a professional first if you have a joint or back problem, recent surgery, a cardiovascular or neurological condition, or if you are pregnant or recently postpartum. Our fitness and safety note has the rest.
What it costs
One of Lucy's sixteen routines is free in full and forever, no account required. The rest is a subscription with a 7-day free trial, priced per App Store territory.
FAQ
Is a five-minute stretching routine enough?
For a single session, it is close to the point where more time stops adding much: the Sports Medicine review found session gains flattening at roughly four minutes per muscle group. What matters more is the weekly total, which it put at about ten minutes per muscle group.
How many stretches fit in five minutes?
Six to ten, depending on hold length and how many need both sides. At thirty seconds a hold, five both-sides stretches fill five minutes exactly.
Is it better to stretch five minutes daily or thirty minutes weekly?
The review found no difference as long as the weekly total was similar, so choose on what you will keep up. Daily tends to win on memory rather than on physiology.
What is the best five-minute stretching routine for someone who sits all day?
Neck, shoulders and wrists if the day was mostly at a screen; hips and lower back if the complaint is lower down. The sequence above covers the first case and needs no floor.
Do you need equipment for a five-minute routine?
No. The sequence above needs nothing at all. A wall and a doorframe extend what is possible if you want to add chest and calf work.
