Hey guys, so I recently caught up with my old boxing coach and I've decided to go back into boxing after a two and a half year break recovering from a major motorcycle crash that has left my left ankle pretty mangled. I've been to physio and received rehab and got the all clear to resume training. But sadly the lack of flxibilty (thanks to inserts) and having a chunk of my ankle removed (thanks to necrotizing fasciitis) makes it hard to skip and at times it can be painful too. Its a real blow because I enjoyed skipping. I know there is no substitute for skipping, but I'm wondering if there are any other exercises that can provide a similar benefit. My coach reccomended either running or swimming. But I was wondering if there are any other suggestions too.
