Okay, so I've been doing cross-fit 3 times a week for about a year and a few months ago I changed up my diet to reduce calorie intake and shed some pounds. I got down to my goal weight and then started doing additional research and found that, of course, I was going about things the wrong way. Calorie intake was way too low and I probably lost a lot of muscle weight. So I decided to change things up, increase calorie intake with mostly meats, vegetables, and supplements (protein powder, salmon oil, creatine, ultra/super-greens). I got myself all excited about the new route I was taking and then BAM! I broke my foot. So I am not able to bear any weight on that foot for 8 weeks. Even after the 8 weeks, I'll only be able to walk...no running or jumping for probably 4-5 months. That means no more cross fit for a while.
I'm pretty much limited to only upper body workouts now. Lots of pushups, pull ups, abs, shoulders. But nothing else really. I'm concerned that without being able to do any kind of "traditional" cardio at all, I'm gonna start putting the spare tire back on. So the question is, what now? Any thoughts, recommendations? All of the typical videos that I see from things like Men's Health that say "really crank up your metabolism" involve movements that require pushing off with your legs...which I obviously won't be able to do for a while.
