Hello Nameless, I see you are participating in another thread which is great, and what you and your husband are being niggly about, is only circumstantial, nobody knows what's going to happen when he's released, we always hope the best will be the case, but you can't judge what his parole is going to entail and how he's going to handle it, you can only hope he is so pleased to be free.
You're right, nobody needs to know anything about him because once someone knows, they tell someone else and say, 'don't tell anybody but ************', then rumours start, you don't need that to begin, otherwise it all ends up a complete mess, that's not fair on you, nor your son, especially when people you haven't heard from for a long time, all of a sudden ring you up and want to know everything, just tell them 'you don't know'.
Doing any exercise at home is not the same as going to the gym, you meet different people, do extra exercises and enjoy the surroundings, whereas at home it's not the same and may not complete them satisfactorily.
You might be able to watch an exercise program on TV, maybe Netflix if you have it, this is cheap for a monthly conscription and has no ads, or perhaps someone else has paid for it and you can use it for free, I have it and both my sons can watch it for zilch and my two little granddaughters can watch the cartoons.
Life is always challenging, it just depends on how we are able to cope with it, so please look after yourself and take care.
