Those sound hard challenges to fit in exercise. There are no easy answers except that even if it is a 15 minute walk it is better than nothing. I did used to think if I couldn't do a decent block it was not worth it, whereas now I realise anything is better than not doing it at all.
Steady week, four good gym workouts and a good walk, and lots of gardening, soil shifting etc in the weekend. A few wines but food has been reasonable.
This week I can't get to the gym as DH is away and I can't leave the young son home alone so I need to fit in walks or bikes or cycles during the day. It is a lovely time of year here though (mid spring) so it should not be too hard to make it work, and a change can be good.
