WIBU to exercise in the garage while DS is asleep?

[DontTouchTheMoustache]

Single parent, DS is 5. I have been indoors for 2 weeks and being in the vulnerable group have not gone for walks etc.
I have already started to put on weight and want to do some cardio but the cross trainer is in the garage which is next to but not attached to the house. Its too heavy for me to move by myself and i couldnt do it while he is awake as he would just try and climb up on it while I'm using it.
I would be in there for 20 minutes, would you do this? i would only be a few feet from the house but prepared to be told that i would be unreasonable.

I would definitely do this. An old baby monitor would be the best solution though.

How about doing one of the exercise classes that are on YouTube so you can do it in your front room? There’s Joe Wicks (the body coach) and there’s Oti Mabuse both get your heart rate up plus there’re suitable for all ages. You can watch them live or when ever. Joe’s is streamed live at 9am and Oti’s is at 11.30 and then she does another at 19.30 for adults

A 5yo should be perfectly able to understand NO and to not climb up on a moving machine. I'd work on his behaviour and do it while he's awake.

Its not just 20 minutes tho, i am wfh so i spend 8am til 2pm working while he has to entertain himself and i feel awful for it but i cant not work and then a switch off to be fully engaged with him until bedtime then have to log back in until around 11 to get my work done so he is actually being very good for a long part of the day

But its just that then when mummy isnt doing work any more he is used to it being his time and also I'm currently his only interaction with an adult so when it is his time i want to be fully focused on him
