....how to get fitter when you are extremely UNfit?

[GreatFuckability]

I don't even know where to start!
Context- I'm 36, I'm a size 22 and I'm incredibly unfit. To complicate matters I have a back problem which really limits what I can do without pretty significant pain.
Nevertheless id really like to try and get fitter (and lose weight ideally, but that's really a secondary concern to me).
There are so many fitness things out there and I really don't where to begin. The idea of joining a gym terrifies me, I've seen the way people on social media talk about clueless fat people and its enough to put me off for life, plus my income is really limited anyway.
I do really like to swim, but again financially I probably cant afford it often enough to make a huge impact.
I know I sound like I'm making excuses, I'm not and I'm really open to any suggestions you can think of, because I really do want to do this.

lots of people have new fancy fitbits and you can pick up last years model on Ebay quite cheaply - I'm going to start walking the 30min school run as I've just given up my job so have no excuse to drive!
Also the 'my fitness pal' app is really motivating.
Set small targets, don't look at the big bewildering picture, just focus on x amount of walking/jogging and losing the first 7lb's.
I wash it was as easy as I make it sound lol but that's my plan, as soon as i've finished this last box of shortbread...

Have a look on ddpyoga.com as that can be done from home too.

Anyone fancy a FB weight loss/fitness group?

(I am also 36, very unfit and need to do something positive to set an example to my kids, never mind for my own health.)

its the people I know who use the gym and then go on social media and make snide jokes about how someone else uses equipment/looks that bother me

I'm actually surprised that anyone would do that as it would make them look awful. Do you actually know people who would do that?

Have a look at the Sports England undefeatable campaign - it’s got loads of ideas for people with health issues or just starting out. www.weareundefeatable.co.uk/

SlackerMum1 it's been nearly three years... I suspect she's sorted it by now

Oh well! It’s still a good website!
