So for the past 3 years I've eaten (to a reasonably strict extent primally) but done relatively little exercise beyond maybe 2 or 3 games of sport a week. I'd (honestly(!!)) just decided to take a bit more control of this aspect of my life and start regular exercise to try and really improve myself when.....I blew out my knee playing one of the aforementioned sports.

I have a ruptured ACL which is basically preventing me doing any kind of driving off or squatting actions seriously (I can walk around OK and jog a bit if necessary but that's about it). I'm due to have surgery on it later in the year but I'm wondering if anyone has any suggestions for good exercise options in the meantime/whilst I'm recovering?
