In reply to candy_girl: if you want to lose weight then firstly, some sort of HIIT such as sprints, burpees, or kettlebells are more effective than steady cardio like running and many forms are less high impact (obviously sprinting is still high impact but bike sprints wouldn't be) so less chance of niggling injuries. Secondly, weight loss is 70% diet anyway.
As for other things you can do, kettlebell circuits, yoga as other have said or even hangboarding if you feel your fingers can handle it are all good options.
