Uh, cardio?
None.
With a calorie restricted diet you need to put on lean muscle, cardio would be counter productive at this point. Lift like a powerlifter, make your mind think it needs every calorie to build muscle, not cardio. For instance, you burn about 450 cals in an hour doing the tredmill, only burn about 300 lifting. Sounds like cardio is better, right? NOpe, it takes aproxomatly 50 calories per pound of muscle to just maintain that muscle, more if you use it. So keep the calories for building muscle, the more muscle the faster the fat drops off. If you put just five pounds of muscle on, that's 250 extra calories you metabolism must come up with just to exist, so 300 lifting plus 250 maintaining is 550, so it's actually faster to loose fat by not doing cardio and just lifting when a restricted calorie diet. Also, our damn bodies adapt to what we are doing. If you run in the morning what does it want to do? It wants to save energy for endurance, carry less weight, ie muscle, and make your metabolism more efficient. If you just lift, it's going to use those calories to build muscle for what it considers survival, so it will concentrate on putting on the beef. Mind you, cadio has it's place, but it's down the road for cutting up and such. I can lose 10 pounds in less than a week. Unfortunatly it's half beef and half fat, but the illusion in the mirror is that I put on 20 lbs of lean beef. It's all illusion. I'm actually surprised you have much fat on you at all only eating 2500 cals a day. I eat about 5-6K a day just to maintain without any cardio, just lifting heavy. When I want to get down to contest weight I'll eat about 2k then two days of dehydration and cardio. Huge ten day difference.
Anyone else have a say? Welcome more advice, I'm just letting you know what works for me, through trial and ERRORS in the last two decades.
PS sex calories don't count.
