With diabetes, exercise is part of managing blood sugar. The US Centers for Disease Control and Prevention (CDC) “Get Active” page sets a goal of at least 150 minutes of moderate activity a week, about 30 minutes on most days. Start with a short, specific goal such as a 10-minute walk after dinner, and don’t go more than two days in a row without activity. Check blood sugar before and after a walk and you’ll likely see a lower number. Check with a doctor before starting anything new or harder.
1. Goal: 150 minutes+ of moderate activity a week — about 30 minutes on most days.
2. Start small, like a 10-minute walk after dinner; no more than two days off in a row.
3. Check blood sugar before and after a walk — it’s likely lower, says the CDC.
How much — CDC
| Type | What the source says | Worth noting (ours) |
|---|---|---|
| Goal | 150 minutes+ moderate a week | — |
| Spread | About 30 minutes on most days | 150 ÷ 5 = 30 (our arithmetic) |
| Format | Needn’t be long or in a gym | — |
| Rest | No more than two days in a row inactive | — |
| Before | Ask a doctor before new or harder activity, and what to avoid | — |
Getting started — CDC
| Type | What the source says | Worth noting (ours) |
|---|---|---|
| Small | A short, specific goal like a 10-minute walk after dinner, then build | — |
| Strength | Or start with strength and stability exercises | — |
| Everyday | Stairs, playing outdoors with children, moving during adverts, lunchtime walks, dancing at home | — |
| Plan | Schedule it, a partner (in person or online), track with an app or log | — |
| Blood sugar | Check before and after a walk — usually lower | No target ranges on this page |
A weekly plan — our example
| Week (our example) | Per day | Worth noting (ours) |
|---|---|---|
| Week 1 | 10-minute walk after dinner, 5 days | 50 minutes a week |
| Weeks 2–3 | Build to 20 minutes | 100 minutes |
| Week 4 on | 30 minutes, 5 days, plus strength and balance | 150 minutes — the CDC goal |
| Rest days | Never more than two in a row | e.g. Wednesday and Sunday off |
The CDC says start small and build gradually, without setting a pace. This four-week plan is our example of that principle; 150 minutes is 30 minutes on 5 days. Logging blood sugar before and after walks lets you see the “lower number” the CDC describes for yourself.
Before and after — our summary
The CDC page gives two safety steps: ask a doctor before new or harder activity, and check blood sugar before and after walks. So each time you step up, ask which activities suit you and which to avoid, and bring your logged readings to the next appointment (our summary). Target ranges and low-sugar guidance aren’t on this page, so get them from your clinician.
What you get — CDC
The CDC lists better sleep and mood, weight loss or maintenance, memory, lower blood pressure, lower LDL and higher HDL cholesterol, and better blood sugar management with lower risk of heart disease and other complications.
Adult activity levels in general are in adult activity guidelines; benefits in benefits of exercise.
Checklist
- ☐ 150 minutes this week — 30 minutes on 5 days
- ☐ A 10-minute walk after dinner tonight
- ☐ No more than two days off in a row
- ☐ Check blood sugar before and after a walk
- ☐ New or harder activity: ask your doctor first
Questions that remain
I’m worried about low blood sugar during exercise.
This CDC page doesn’t cover hypoglycaemia thresholds or what to do. If you take medication, agree pre-exercise levels with your doctor.
What time of day is best?
The CDC gives a walk after dinner as a starting example only; it doesn’t name a best time.
