What exercise might I actually grow to enjoy if I tried it?

[StillMedusa]

I'm 55, slim, and have a bad sacroiliac joint and low back problems.
I can't run (had a triple prolapse and hysterectomy after 4 children and was told no high impact stuff as I could end up with a vaginal vault prolapse)

I'm unfit. Yes I walk the dog but that's it.

I used to do Taekwondo (am a first Dan black belt in fact.. gained it at 48) but after a nasty dislocated thumb I gave up.. I was flexible then, but not any more. I have a weak core.

I kayak/paddle board a bit with Dh but only in summer.. getting cold and wet is NOT my thing!

I'm menopausal/post (who knows I'm still taking HRT)

I WANT do do something that will keep me healthy! I have an adult son to care for (autism) and a toddler grandchild I look after several days a week, plus I do supply in school. My diet is not terrible but I do have too much wine.. and that's not going to change!

I need something that will give me a buzz like Taekwondo used to... something I will commit to, so probably a class? I don't want to lose weight but I want to improve my flexibility, and cardio health.

I really fancied an adult ballet class but there are none on the day I'm free. There is an adult beginners gymnastics but I'm a bit scared of that! Pilates bored me stupid when I tried!

There must be something for me out there! Help!

Spin!
I'm hooked.

I love Vinyassa Yoga. You can get properly sweaty on just the space of a yoga mat and when you master a new posture the sense of achievement is brilliant

being an anti social bastard I subscribe to glo.com and can exercise whenever it suits me

I used to go to class called body balance, it was great for flexibility and cardio health!

Zumba is really high impact unfortunately.

I’ve been doing P.Volve since lockdown and absolutely swear by it. Very gentle on joints and focuses on your core. Some of the classes have gone a bit more cardio-focused recently but the slow and steady stuff is brilliant.

You could try sea swimming if that's accessible, no chlorine issues there. Some places have adult ballet classes. I tried swing dancing and it was fun. Roller skating? I go to yoga flow but as pp said, you do need to find the right teacher.
