Hey guys I have a few questions for those who are already physically fit and very athletic. I used to do MMA training in Alabama with a BJJ black belt and Greco Roman Wrestling specialist, and I was in good shape. About a year ago, however, I got in a bad wreck, which caused me to start smoking and quit training. A year later I find myself in the worst shape I have ever been in. I mean, I'm talking I can't even run a half a mile. I'm not fat, and I look like I'm in shape, I just have terrible endurance.

Right now all I do is lift weights, but that's not building my cardio at all. In two weeks I start training for the army, but in order to qualify I have to run a mile in 8:30. What is the best way to build my cardio in two weeks, starting from scratch??? If anyone could help me I'd greatly appreciate it...
