Tonight was more like it. I've been struggling with cardio that any longer that 35 minutes. Tonight was much better. I actually feel like I'm starting to transition from Powerlifting (anaerobic) to Cardio Monster (aerobic). Of course I'm exaggerating extremely with the "Cardio Monster" comment.
alternate the following
Stationary Bike - 3 sets/15 minutes.
Sit Ups - 3 sets/25 reps.
Tomorrow morning I'm off to the base gym to walk / jog around the indoor track. Hopefully my left leg holds up. If not I'll jump onto the arch trainer.
