Is doing cardio 2x per day a bad idea?
Ok, so I'm trying to drop a bunch of weight (45lbs down, another 150 to go) and I've been doing cardio every morning for about 5-6 weeks now. I've started getting used to 45 min at 2.5-3mph but toward the end of the day I still have enough energy for another round on the treadmill, and it's really become my favorite part…
