I believe there are two types of people - those who inhabit their body', and actively enjoy moving it about, and those who inhabit their head and see the body as a way of transporting it about.
The two will never understand each other.
The former type say 'just find an exercise you enjoy', not understanding that for the second type there is no such thing. Exercise in itself - the getting breathless, the tedium, the sweat, the discomfort, the pointlessness - is what is not enjoyable.
My only motivation for doing it is to not be as immobile as my old mum was, and to maybe look slightly less repellent. However, these things are not measurable. I never seem to get stronger, or less repellent. So as I don't enjoy it at the time either, motivation is non-existent.
The thought of team sports chills the soul. The thought of park run makes me want to throw up. So, weights in front of YouTube - or at the gym as long as no one talks to me or looks at me - is the only way forward. And dancing in the kitchen.
