55yo looking for the right approach to exercise.

[MonkeyTennis34]

Apart from walking the dog, I do no other forms of exercise and I know that I really need to!

I'm a healthy weight so it's not about weight loss, just getting fitter.

I've noticed a few aches and pains in my hip area...would something like Pilates be useful for this.

I've done HIIT in the past but would like to try something different.

I'd like to build my core strength as well as work towards a higher level of fitness.

We have a treadmill at home which I've used in the past but I guess that only addresses cardio.

Can anyone suggest a form of exercise they might suit me?

Happy to use YouTube.

There is a physiotherapy clinic near me that runs various classes, one of them is a better bones class for older women. I went to them for a few months when my personal trainer was off with an injury and they were pretty good, a maximum of 6 in the class and all over 50. Could you have a google and see if there is anything similar near you?
