Start here
Follow the aftercare given by your donation service before starting a saved routine. Check the donation type, its activity restrictions and how every movement uses your donation arm. Do not treat a stretching label, short timer or feeling well as clearance. Postpone movements that conflict with your instructions and ask the service about anything unclear. Stop if you feel faint or the needle site starts bleeding.

When to get medical help
If you feel faint or unwell
Stop the activity. NHSBT advises telling someone, lying down and raising your legs if possible, then getting up slowly once well enough. Follow the full donor aftercare, and contact the service if worried. Do not keep moving to see whether the feeling passes.
If the needle site bleeds again
Stop and follow the service's bleeding instructions. NHSBT advises sitting down, raising the arm and pressing on the bleeding area for at least five minutes. Its helpline offers further advice for prolonged after-effects. Persistent or concerning symptoms need appropriate medical help, not another stretch.
Use your local emergency service when emergency care is needed. These examples are not a complete symptom checklist.
1. Start with your own aftercare sheet
Keep the donation type, time, arm used and service contact together. Read the advice issued for that appointment. Do not transfer whole-blood advice to plasma or platelet donation without checking. This guide helps organise questions; it does not assess recovery, blood levels or fitness to exercise.
2. Read the restriction, including its time wording
The American Red Cross advises avoiding heavy lifting and vigorous exercise for the rest of the day. NHSBT's preparation page advises avoiding heavy exercise for 24 hours. Keep those source-specific periods distinct. If written advice and a webpage seem different, ask your own service rather than choosing whichever allows an earlier workout.

3. Inspect support and transitions, not just the target area
For each movement, note the starting position, which arm supports weight, whether you pull or hold a prop, and how you get down and up. A back-focused or short routine can still load the donation arm. An unclear picture is a reason to read or ask, not to try the position as a test.
4. Make a three-entry question sheet
Fictional example: your saved sequence includes a wall-supported movement, a floor position reached using both hands, and an overhead reach. Copy each instruction beside the relevant aftercare restriction, then mark the unresolved loading or transition question. These are examples to inspect, not a recommended sequence or confirmation that the final movement is suitable.
5. Keep the app in a planning role
Unknot on iPhone offers previews, numbered movement instructions and pause controls for inspecting a sequence. It is not a donor recovery programme and cannot approve an activity. You can leave the routine unopened for practice and keep a question for later; completing a timer is not a recovery check.

6. Record the answer you actually receive
When contacting the service, explain the donation type and time, any symptoms, and the exact movement or support you are unsure about. Keep its advice and when it should be reviewed. Do not turn one person's answer into a universal waiting period or compensate for a missed session with extra exercise.
Bring the movements, not only the routine name
Put the aftercare sheet beside the full movement list. Resolve the unclear parts before following the sequence, and keep the option to postpone it.
Questions before you start
Is a shorter or gentler routine automatically allowed?
No. Fewer minutes do not remove arm loading, strenuous effort or a difficult transition. Compare the actual instructions with your donor aftercare; do not use the routine name as permission.
Can I use the same waiting period after every donation?
Do not infer that. Use the instructions for your donation type, service and circumstances. A quoted period is a restriction in its source, not a promise that every movement becomes suitable when that time ends.
