I was working out at school but probably only 2 times a week. Now I'm pretty much going every day alternating threw 3 routines. On all days if I have the energy and my legs aren't sore -- leg press, calf raises and then abs/obliques Day 1) Chest/Tri Day 2) Back/Bi/Shoulders Day 3) Cardio Day -- Stairs (80-100 floors), biking, elliptical. I'm working out with my older brother and his friend who are both pretty huge and know what they are doing so they are essentially training me so I do everything correctly. Do the above workouts look OK? I'm around 6'3" and weigh 185 pounds but I personally think I have a very mini-gut and my legs could use the cardio which is why I do it...and I'm trying to lower my BF %. How detrimental is the cardio to me gaining muscle size? Also, on chest days I consistently notice my left arm is MUCH weaker if I'm doing bench press or dumbbell press...more obvious on the latter. Likewise my left chest muscle is also a lot weaker, visually. Is there anything I should be doing to help correct this? It has been like this for a while. I had surgery a while back and they severed some nerves so I can't really feel my triceps at all and I think that may be causing this...but the thing is I can't feel my left or right. Lifting Stats Bench Press - 135 (the bar weighs 45 pounds right?) Dumbbell Press - 60x2 Incline - 50 or 55 x2 Curls - 70-80 pound bar. Leg Press - 290-335 pounds. Calf Raise machine (it has an extension arm outwards so it is basically based on leverage so weight means nothing but...) -- 70 pounds Supplements - varies between N-O-XPLODE and Fast Twitch - Cytogainer or Muscle Milk -- whichever is available. ----------------- 1) Is cardio very detrimental to muscle/size gain? 2) Why is my left arm/chest significantly weaker than my right? I'm left handed.
