Lap Swimming
Pool lengths using one or more strokes.
How to start
Start with 20 to 30 minutes in a pool, mixing lengths with rests at the wall. Choose the slow lane if there is one.
How to progress
Add a length or two every session, cut the rests, and add a second stroke. Swim three times a week as it gets easier.
What the evidence says
Evidence: moderate
A 2024 review of 136 papers found a range of physical health benefits linked to recreational swimming. A 2025 study of 10,218 older US men found that swimming at medium or high intensity and volume was linked to 19% lower mortality than not swimming (hazard ratio 0.81), but the range (0.63 to 1.03) was too wide to be sure. These are observational studies.
Take care: Never swim alone in deep water if you are not a confident swimmer. In a pool, ask the lifeguard if you are unsure. Check with a GP if you have a heart condition, asthma or epilepsy.

12-week starter plan
You should be comfortable in the water. Count lengths, rest when you need to, and build the continuous swimming slowly.
Tick each week as you finish it; your ticks are saved on this device only. Repeat a week if it felt hard. Weeks 4, 8 and 12 hold steady so you can settle. This is a general plan, not medical advice.
