I'm overweight. Technically obese, but with decent posture so I don't look it - just "cuddly" as a pupil described me. 
Part of the issue is food - DH is 6ft 2" and eats appropriate to his size (well, okay, probably a bit too much) but makes me the same size of portion.
Due to childhood issues, I always clear my plate (food=love, so not eating means I'm rejecting that person) but I'm now addressing this and have talked to him about it.
So, now it's the exercise bit. And I cannot bring myself to do it. It's not time (lockdown has proved that), it's the fact that I HATE exercise. I've tried most things and it's the feeling of sweat, the having to put on different clothes and then shower after - I just can't be bothered. Plus the fact that I'm overweight and unfit, so when the exercise video says "do xxxxx" I just can't - and then I lose motivation.
How do I break this mindset? Is there an equivalent "how to motivate for exercise" Paul McKenna?!
