The Gym Didn’t Work
I’ll be honest about my history with exercise and T1D, because I think the honest version is more useful than the version where everything eventually clicks into place through discipline and determination.
I tried the gym. It didn’t work — for several reasons, and not all of them were about T1D.
Self-discipline was an issue. Without someone else to be accountable to, without a structure that required my presence, the gym became optional. And optional things, when you’re managing something as relentless as T1D on top of everything else, have a way of becoming not-happening.
When I did go, I didn’t really know what I was doing. The weights section in particular — I was guessing. And the blood sugar response to the sessions was erratic in a way that genuinely put me off. My levels would drop significantly after working out, and managing that added another layer of complexity to something I was already finding difficult to sustain.
I also felt like I stuck out. Alone in a gym full of people who seemed to belong there. That feeling — of not fitting anywhere — was one I was already carrying because of T1D, and the gym amplified it rather than helping with it.
Home Workouts Didn’t Work Either
I tried working out at home. Same story. Without the structure, without another person, without anywhere to be, the motivation simply wasn’t there consistently enough to build a habit.
After that I stopped trying for a long time. My movement was my walks — long ones, regularly — and while those were genuinely good for me physically and mentally, I wasn’t finding anything that felt like exercise in a structured sense.
The truth underneath all of this, which I’ve come to understand with some distance, was that the gym and home workouts didn’t work partly because I didn’t feel like I fit anywhere. T1D had already made me feel different, separate, other. Environments where I was alone with that difference didn’t help.
What Eventually Worked and Why
Relatively recently I found Pilates. Small group sessions. And something clicked that hadn’t clicked before.
The sessions are manageable for my T1D — the blood sugar response is more predictable than it was with weights-based gym work, and the lower-intensity nature of it means the post-exercise drops are less dramatic.
But the more significant thing is the group. Small enough that it feels like a community rather than a crowd. A context where I fit — where nobody is performing for anyone else, where the focus is on what your own body is doing rather than how you compare to others.
That sense of fitting somewhere is something I’d been missing from exercise for a long time. And finding it has made the difference between something I do consistently and something I abandon.
What T1D And Exercise Actually Involves
For anyone newer to managing exercise with T1D, here’s the honest picture:
Exercise affects blood sugar in ways that vary significantly depending on the type, intensity, and duration of the activity. Aerobic exercise (cardio, walking, cycling) tends to lower blood sugar during and after. Anaerobic exercise (weights, sprinting) can raise it initially through cortisol before dropping it later.
There is no universal formula. What works for one T1D at one intensity level on one day may not work in a different combination. It requires trial, observation, and adjustment — and that adjustment process takes time and can be genuinely discouraging before it becomes familiar.
A few things that help: checking levels before, during, and after exercise until you know your patterns. Having fast-acting glucose available. Being willing to reduce insulin or increase carbs beforehand based on your own data. And talking to your diabetes team about your specific management approach for exercise, rather than guessing.
The Wider Point About Finding Your Fit
What I’ve learned from my own history with exercise and T1D is that the activity matters less than the fit. The right exercise is the one you’ll actually do — consistently, without it feeling like punishment, in a context where you feel like you belong.
For me, eventually, that was Pilates in a small group. For you it might be swimming, or cycling, or dance, or walking — which, incidentally, remains one of the most consistently beneficial things I do for both my blood sugar and my mental state.
Why Many Type 1s Fear Exercise
We’ve all been there. You’re ready for the gym, then bam — your blood sugar tanks halfway through. Or you finish and shoot up to the stratosphere. It’s soul destroying. After a few of those experiences, you start thinking, “Why even bother?”
But fear keeps you stuck. Exercise is not your enemy. Misinformation is.
The Dynamic Dance: Insulin and Glucose
Think of insulin and exercise as dance partners. Insulin lowers sugar; exercise uses it for energy. But when you move, your body gets extra sensitive to insulin. That’s why the usual doses might hit harder than expected.
Basal and Bolus: Know Your Team
Basal insulin runs quietly in the background. Bolus handles meals. During workouts, bolus usually causes the drama. So, most people tweak that one first. Long sessions, though? Basal can join the chaos too.
Cardio: The Long Game
Endurance workouts can drain you — and your glucose.
That slow burn means you might need more snacks and less insulin.
Don’t be scared to pause for carbs. The treadmill will still be there.
Mindset Over Fear
You’ll mess up sometimes. You’ll go low, or spike, or feel frustrated.
That’s part of the process. You’re learning how your body works.
The goal isn’t perfection — it’s progress.
Tech and Tools Help
CGMs, pumps, sensors, alarms — use them.
Carry glucose tabs. Wear medical ID.
Preparation = freedom.
Know When to Rest
If you feel shaky, dizzy, or “off,” stop.
Your body isn’t being dramatic. It’s protecting you.
Rest days build strength too.
Encouragement
You can do this. You can lift, run, box, dance — whatever you love.
You are not fragile. You are powerful, adaptable, and capable of figuring this out.
