I just wanted to share some of my fitness advice. I'll have to post pics soon, not out of vanity, but to prove my legitimacy in giving advice in this area, lol. But for now, here's just my advice.
First of all, if you're looking to get in shape, you need to realize muscle burns twice the calories of fat. If you want to effectively burn fat, you need to gain muscle. So I highly recommend getting into body building right off the bat. Start with a 3 day split and lift what you can, and learn all you can about body building. The other thing I recommend is the P90x. It will give you RAPID results, and if you're into bodybuilding it works. People are shocked when I tell them all I do is the P90x when they see how big my arms are. The thing is, using your own body weight, a chin up bar, and some weights and/or bands are all you need. I never bench but I have a crazy ripped chest - I just do the P90x. The P90x requires like, 2 hours out of your life a day at first, because you'll hit the pause button, and an austere diet, but I literally saw results in 2 weeks. When I went to the gym and did a my regular body building split I never saw results that fast. You can get the P90x much cheaper on Amazon or eBay, but make sure you get a 100% legit copy with the NUTRITION PLAN.
Secondly, I ignore the P90x supplements, I know better from body building. It's not that I am arrogantly asserting I am more intelligent than Tony Horton and the Beachbody staff, it's just the people at bodybuilding.com are smarter, and I learned from them, and through experience, what works. The P90x post work out formula is mediocre. What you should be drinking is some water until you cool down enough to drink whey protein or a whey protein Isolate like IsoPure.
Here's what I use for supplements. They are a HUGE part of your workout game. They will give you the edge, and taking them motivates you to work out, especially the pre-workout formulas.
Optimen MultiVitamin (best multivitamin out there, plus it's wicked high on zinc so you rarely catch colds)
Gold Standard Whey - Although IsoPure is better if you can afford it. If you use Gold Standard, I recommend using one scoop (25g's of protein) in 1% or skim milk, which also has protein. It doesn't mix well with water. You don't want to use two while cutting because it has 120 calories per scoop, and the milk has calories too. However, IsoPure has 105 calories per scoop, and it mixes with water just fine, it's almost like juice, so you can do two scoops for about 50g's of protein in water without the fat or calories milk has, plus they have a zero carb version. Personally I use Gold Standard, because I'm poor and I just dropped $45 on Animal Cuts.
Jack3d or Smash Fully Loaded pre-workout. Jack3d is the better route, but I am currently going through a jar of Smash.
AnimalCuts - they are probably the best fat burner you can buy. It's $45 or so for a 3 week supply. You take one pill in the morning pre-workout, and then you take another one like 5 hours later, which is a diuretic, which basically causes you to literally defecate excess body water and other product. Very effective fat cutter.
An alternative fat burner is RippedFuel Xtreme. I recommend this or Lipo 6 if you cannot handle the diuretic from AnimalCuts or the other things it does to your body.
Flax oil pill for the Omega 3's and heart health. A healthy heart goes a long way during cardio, and the Omega 3 fatty acids can actually cause weight loss.
In my opinion, the most important supplement is your multivitamin. Also, everyone loves creatine and people will tell you to use it especially while cutting, but, I don't recommend it, because it causes body mass bloating all over. This can do weird things to your body, such as cause you to gain a waist size (muscle around the waist bloats).
