Why Masters Swimmers Should Warm Up Before Getting in the Pool
Think back to swimming training 20 or 30 years ago. For many swimmers, the routine was simple: arrive at the pool, get changed, swing your arms a few times and jump in. The first few hundred metres were your warm-up.
For some Masters swimmers, not much has changed.
These days, you might arrive straight from work, after a long drive or with just minutes to spare before your lane session starts. It's tempting to assume that because you're about to swim, you don't need to do anything beforehand.
But what if those few minutes on poolside could be more purposeful?
Pre-pool preparation isn't about making your training more complicated. It's about giving yourself a repeatable way to transition from everyday life into swimming.
What is a pre-pool warm-up?
A pre-pool warm-up is a short sequence of land-based movements performed before entering the water. It may include gentle cardiovascular activity, controlled mobility, low-load muscle activation and progressively more dynamic movements.
Its purpose is to help prepare you for the session ahead — not to leave you tired before the first length.
A land warm-up is different from, and does not replace, an in-water warm-up. Once in the pool, you still need an appropriate progression into the main demands of the session.
Why might Masters swimmers overlook it?
There isn't one explanation, and we shouldn't assume that every swimming club trained in the same way. But a few situations may feel familiar:
- It's not what you grew up doing. If your childhood club relied on a few easy lengths at the start of every session, you may never have developed a separate poolside routine.
- Time is limited. Masters swimmers often fit training around work, family and other commitments. Arriving five minutes early can feel like a luxury.
- The water warm-up feels sufficient. An easy swim is important, but it doesn't mean a brief land-based transition can't also be useful.
- There is too much conflicting advice. Bands, stretches, jumping exercises, shoulder drills: it's difficult to know what is actually relevant.
- Poolside space is limited. Some facilities offer very little room, so a practical routine needs to be adaptable.
These are plausible everyday barriers, not findings from a survey of all Masters swimmers. The point is simple: a useful routine should fit the swimmer and their setting.
Why warm up before swimming?
1. Gradually increase activity
Warm-ups commonly aim to increase muscle temperature, circulation and cardiovascular activity before more demanding exercise. Moving gradually from rest to activity can be more deliberate than asking your first length to do all the preparation work.
2. Explore movement you will use in the pool
Swimming involves coordinated movement through the shoulders, upper back, hips and ankles. A few controlled movements on land can help you work through comfortable ranges and become aware of how you're moving that day.
This isn't a competition to achieve the deepest stretch. You do not need to force extra range or push into pain.
3. Rehearse control before speed
Some warm-up exercises focus on movement quality: controlling your shoulder blades, trunk and hips, or rehearsing a streamline position. These exercises are a way of preparing movement, not a substitute for developing strength over time.
4. Prepare for what today's session actually demands
A relaxed aerobic session and a sprint-focused session may call for different levels of preparation. The final part of a warm-up can become more specific, without becoming exhausting.
5. Establish a consistent routine
For busy Masters swimmers, a familiar sequence may remove guesswork. The aim is not perfection: it is to have a short routine that you understand, can adapt and will realistically repeat.
What does RMAP mean?
One useful way to organise land-based preparation is RMAP: Raise, Mobilise, Activate, Prime. This four-stage approach is used in swimming guidance published by Swim England in collaboration with British Swimming. OXOLT also organises its existing warm-up video library using these stages.
R — Raise
Start moving and progressively elevate your heart rate and body temperature. Depending on space and ability, options might include marching, heel flicks, high knees or gentle jogging on the spot. Begin easily rather than making this an intense conditioning circuit.
M — Mobilise
Move through comfortable, useful ranges of motion. Controlled thoracic rotations, wall slides or streamline reaches can help you explore relevant movement before swimming. Pick a small number of exercises rather than trying to stretch every joint.
A — Activate
Introduce low-load movements that involve muscles and patterns relevant to your swimming. For example, the OXOLT exercise library includes shoulder-focused movements and a glute bridge with a streamline position. Focus on control, not fatigue.
P — Prime
Progress towards the speed or movement demands of the session. This could include a small number of controlled, more dynamic repetitions. The right choice depends on whether you are preparing for routine training or a race — and how you feel that day.
Remember: RMAP is a framework, not a fixed list of exercises. You don't need to complete every exercise in every category. A sensible warm-up leaves you feeling prepared rather than exhausted.
What does the research actually tell us?
It is worth separating broad warm-up evidence from claims about one particular pre-pool routine.
- Warm-ups can benefit physical performance. Fradkin, Zazryn and Smoliga's 2010 systematic review and meta-analysis found a generally positive effect of warming up across sporting activities. That is supportive background evidence, not proof that one specific RMAP sequence is optimal for Masters swimming.
- Swimming-specific results are more variable. A 2021 systematic review of sprint swimming reported relatively small and inconsistent performance effects across studies. This is a reason to individualise preparation rather than promise a guaranteed time improvement.
- Maintaining readiness after a water warm-up matters on race day. McKenzie and colleagues' 2022 systematic review examined interventions after an in-water warm-up, during the wait before competition. It found potential benefits from selected approaches to staying warm and active. It did not directly test the benefits of doing RMAP before getting into the pool.
- There is no single proven perfect protocol. A 2022 scoping review of swimming warm-up studies highlighted differences between approaches and gaps in the evidence.
So the sensible conclusion is not that every Masters swimmer needs an identical ten-minute routine. It is that a brief, appropriately paced preparation sequence is a reasonable coaching approach, while the precise exercise choices and performance effects require context.
Does pre-pool preparation prevent shoulder injuries?
We should be careful with that claim. Swimming shoulder problems can have multiple contributing factors, including training load, capacity and individual circumstances. A short land warm-up has not been established as a guaranteed way to prevent them.
Shoulder strength and longer-term exercise programmes are separate topics from the immediate warm-up before a swim session. If a movement is painful, stop or adapt it; if you have persistent pain or an existing injury, seek advice from an appropriately qualified healthcare professional.
How long should a pre-pool warm-up take?
It doesn't need to be elaborate. For many routine training sessions, a practical starting point might be five to ten minutes, adjusted to your ability, available space, session demands and the in-water warm-up that follows. That range is a coaching suggestion — not a scientifically established universal optimum.
If time is tight, doing a few deliberate movements may be more realistic than abandoning preparation because you cannot fit in a long routine.

These demonstrations are an exercise library, not a prescription to perform all 25 movements before every swim. Our follow-up guide will show how to put selected exercises together into a short, repeatable routine.
Pre-pool preparation and your in-water warm-up
Pre-pool preparation is only the beginning. Once you enter the water, allow time to progressively find your stroke, build intensity where appropriate and prepare for the main set or race.
On race day, timing matters too. Avoid completing a good warm-up and then spending a long period getting cold. For a fuller look at competition preparation, read our Masters swimming race-day timeline (check this link against the published article URL before posting).
The OXOLT approach
At OXOLT, we believe Masters swimmers deserve more than a collection of disconnected exercises. Swimming, strength work, mobility and recovery should support the same objective, with training adapted to the individual.
Pre-pool preparation is one small but useful part of that picture.

Final thought
You don't need to copy an elite swimmer's warm-up. And you don't need to spend half an hour on the poolside.
Start with a few purposeful movements. Learn what works for your training. Keep it practical enough to repeat.
Prepare with purpose. Then get in and swim.
