To cancel my gym class I’m booked into tonight?

Why did you post this? What do you actually want from it?

Because people are telling you not to go and you're banging on about being fat. It's all very weird. One missed gym session is going to make fuck all difference.

A lot of people have given you a lot of advice but you're clearly going to do what you were going to before posting.
FWIW, a good habit is listening to your body. If you're desperate to do something, go for a walk or do some exercise at home.

Don't go to work. Don't go to the gym. Don't go on public transport.
It's pretty basic behaviour, you are unwell, don't spread it.

I don't understand why you're asking. You don't need permission to please yourself.

You are setting yourself up to fail.

I guarantee you that going every day is not going to last and in 6 weeks time you won't be going at all. For someone who is starting from zero exercise and is obese, you need to ease yourself in and build a natural routine. Start with twice a week.

I genuinely can't believe this is something you need to check on MN about

Don't spread your germs. Please.

Go for a walk at lunchtime - to the nearest pharmacy for some cold medicine. Or after work before you go home - gentle exercise achieved.

Coughs and colds can incubate for 2 weeks before becoming symptomatic.

And illness isn't "any old excuse not to go"! This isn't sustainable. A good habit is more like every other day but with flexibility to accommodate the changes we get in life

Sorry you don't feel very well.
But
You sound really difficult. Just about everyone has given you good advice and you've basically argued back on every point. The class cancellation is literally exactly within their terms yet you're still asking here. And yeah, go to the gym and put your germs all over the place, and now the new thing, add your germs to public transport, suddenly introduced out of nowhere.
You're contrary and difficult.

Going every day isn't a good habit though. Go every second day to start with. You need to build in rest days too

Just alternate gym days with going for a walk?

Well, you've either got a cold and are therefore infectious - don't go to the gym and spread it around, or you haven't but you feel rubbish - go to work if you have to, skip the gym and rest to aid recovery.

When I get a cold I just stay in bed and rest as much as possible, knocks days off the total time spent full of cold (which used to be over a week, so big difference). You probably don't have this as an option, but resting instead of working out is a no-brainer. You won't get well quickly if you're pushing yourself.

It's annoying when we're determined to follow a path and feel illness is pushing us off that path. But it isn't. You're just pausing for a breather. You can pick the reins again when you feel better.

Fuck knows what your going to do when you havnt got social media to answer these life important decisions 🤷‍♀️

You shouldn’t be going every day anyway. You need to build in rest days.

you need to work on your mind set here.

Hang on. when I read you were going to the gym anyway I was actually thinking you should go and explain to the instructor you're going to take it easy because I'm all about building strong habits.

I run a hiit studio by the way and have helped hundreds of women lose substantial weight who have been obese for years.

BUT

Then I read you're planning to go everyday. You seriously need to cop on. You're setting yourself up to fail. Your body needs to recover from yesterday. Go for a gentle walk. Track your food. Drink water, get to bed early.

Three hiit sessions a week, improved eating habits and move your body everyday for the sake of moving it. That is all.

Good luck OP. You can do this.

You can't go to the class when you will pass the sickness on.
Two of DD'S friends wouldn't miss school for 100% attendance coughing, spluttering everywhere, head on desks all day, DD got sick, tested positive for covid, DS is immun-compromised. Stay at home.

I hosted a gathering last year (nothing fancy and 100% could have been rearranged!). A friend turned up clearly unwell. She thought this better than cancelling.

Everyone else was ok, but my immune system is poor. I ended up far, far worse than she was - almost hospitalised, I lost half a stone in 5 days, couldn’t swallow more than the tiniest sips of water and it was touch and go whether I would make it on holiday 10 days later. All because she didn’t want to cancel.

I love her, and she’s normally a lovely, thoughtful friend. I’ve never mentioned it, but obviously she’s aware because she knows how poorly I was etc. It still blows my mind to this day that she came, and as others have said - when you choose to spread your germs, you have no idea who will be receiving them and how the possibly minor illness in you will present in them.

What a lot of silly drama over nothing.

Nobody said to do nothing at all
Most people said to go for a walk or do some exercises at home
You're choosing not to listen to them and want to martyr yourself

Why every day from the start?
That's a sure fire way of giving up immediately anyway
Start with a couple of days a week and build up. When I started going I went 2 days a week and built up from there by adding an extra class every so often. You need rest days for recovery
