Hi and welcome.
First thing i'd say is if you hate exercise don't worry about it. Really you can lose most of the weight you want to lose without formal exercise at all. And it is quite easy too. So do your thing without guilt and let your hubby go for his run and whatever he wants. Don't get into debates with him about it. Soon you will start seeing the loss and then you can just say to him, stop worrying about me and i'll stop worrying about you and what you are doing.
We are both doing what we think if right for us.
So where am i coming from on this. Well i quite like exercise but i go for long periods of not doing it and in the past i have done lots of it on my weight loss programs. But of course the weight always came back when i stopped exercising. And i always did either because i ran out of steam or a life circumstance change.
So this time i didn't even start out with any exercise except what i would do at home which was sometimes some gardening and sometimes walking on the beach with the dog but according to no program, just when i felt like which wasn't so terribly often. Of course on the days i did some heavy duty gardening, i noticed a bigger loss.
Anyway, just so long as your food intake is tailored to your lower calorie intake you should be fine.
Of course over the long haul, it is better to do some sort of exercise but you will find it much easier and more enjoyable when you are thinner. The thing is with more muscle mass your body will function better and lose weight better. But you don't need to worry too much about that now i think.
But be aware of your movements and try to take the options that are bit more physical than what you'd normally do. Don't take the lift, take the stairs. etc.
Another thing that people say is really helpful is getting something to count your steps. I can't remember how many steps a day its good to work up to but they say that when people wear these things, they find that gradually they start increasing the number of steps they do and that's how they benefit you.
Another point about exercise, it is hard and often unpleasant when you start from a very low fitness base. That's why if you are going to exercise, its better to increase what you do quite gradually so that you aren't putting unnecessary strain on your body. But when you start to feel fit, exercise can become intensely enjoyable.
one other idea that you might want to think about, try to let go the message you send yourself about how you hate exercise. This message as its often repeated sets you up to never ever get started. It becomes some sort of a pressure and a cause of stress when you think you hate doing something or don't want to do it but feel you must. so just try to shelve you feelings about exercise. You don't need to do it right now. Later on you may feel like trying the odd thing or two. The main thing is to get weight off and you can do most of that with diet alone.
So yes i only took up regular exercise recently, after more than three months of dieting and weight loss. I was at the top of healthy weight range when i started my running program. And by this time, i weigh less so running is a lot easier on the body.
