Btw Victor, my partner had a badly fractured ankle a few years ago, that he wasn’t allow to put any weight on.
Do you have an exercise bike? That’s an amazing way of getting exercise without putting much weight on your ankle. At first, you can even make sure you use “the other leg” to do most of the work and just let the broken-ankle leg “come along for the ride”.
My partner actually used his real bike for exercise while he was off sick from work, he’d strap his crutches to the bike and then go for bike rides (to get exercise) and go on bike rides to hang out in cafes etc.
It a) really helped his mood to not be stuck indoors all day and b) it made his healing sooooo much faster and better.
I don’t think the exercise was important in terms of “weight loss” so much, but because it activates your immune system and it gets your lymphatic system going, etc.
A friend of ours fractured his ankle a couple of years later and did none of this - just spent the entire time at home on his couch and boy was his healing slow and complicated and he felt crap and complained throughout the whole thing.
If you don’t have an exercise bike, try asking friends/ relatives if they have one they’ll loan to you for 8 weeks. Most people don’t use theirs (hahahaha) and would be happy to lend it to someone who needs it for recovery. Also, they are available 2nd hand quite cheaply online, because many ppl buy one intending to use it and then find that they never do, so there’s quite a few bargains to be had re 2nd hand exercise bikes : )
I have one and I like using it while watching TV or dragging it out into the garden and using it in the fresh air and sunshine.
