I walk every day and so my fitness is okish. I eat healthily and am a good BMI. But I have a desk job and can be quite sedentary in the evenings too.
I'd like to do some exercise at home to build muscle as I feel mine are wasting as I age, but have no idea where to start. I'm happy to buy some weights but I have no idea which kg I'd need or what to do with them.
Can any of you recommend any YouTubers or online exercise programmes? Or helpful resources for ageing weak beginners!
