My first attempt at following the Bfold principal of improvement..
IMO what works for my goals is a combination of Moderate Cardio and Intense Lifting...
liquid is asking what I perceive as a Cardio conditioning question when he says "in shape"
You aren't going to improve Cardiovascular conditioning by doing ONLY Anerobic lifting IMO.
True, the strength training will help on the obstacle course, but the endurance of making that strength last would be gained with some Cardio as well...
liquid, I can't run well either and found for cardio conditioning especially for the upperbody without the impact, swimming is fantastic.
The other option is to either do Super Sets with little rest between, or to get on a treadmill and fast walk with the ramp set above 5% incline...
