I like to run. Don't hold it against me -- I'm not a masochist or a "running high addict" or anything, I just like to run. It's a convenient and interesting way for me to get a workout.
Admittedly I'm not really built for it (41 y.o., 6' 220#, shooting for < 200#), but that might work to my advantage since I get a good workout carrying my fat rear end on a short run :-).
As a sole form of exercise it is somewhat limited though, and I am constantly worried about injury (had a minor soft tissue injury a couple of years ago that sidelined me for about 6-8 weeks). I also find it hard to get a good run without eating carbs before and/or after, and I don't really like carbs.
I've been doing about 3.0-3.5 miles 3-4x per week, and really I don't have any interest in doing a lot more than that. Partly due to time constraints, and partly because it just gets boring after ~30 minutes, and partly due to concerns of injury.
So I have started on the kettlebells, both to get some strength training in, and to take care of my joints (hard to imagine how you might hurt yourself with a kettlebell unless you hit yourself in the head with it). I LOVE it, great full body workout and definitely gets the heart rate up, lots of variety and different body parts involved, and easy to do any time of the day.
So I am wondering, should I drop the running completely and replace it with kettlebells? I'd hate to lose the cardio fitness I've built up, I am not sure how effective kettlebells are for cardio. Or, alternate, one day running, and one day kettlebells? Will the two forms of exercise complement or cancel each other? Introduce something else? I am not a gym person so it would have to be something I can do at home, with minimal equipment. Anyone have any suggestions?
My fitness goal is to stay healthy and lose some fat (shooting for 20 lbs), not concerned about overall weight, don't want to bulk up but some more muscle would not be bad.
