Step 1) Do a lot of research into form. Once you feel you have the basics down, up the weight, but not until you start on Step 2. I have found some of the good technical vids on youtube are great for getting form down.
Step 2) Get a spotter, someone that knows their stuff a little bit preferably. If this means you have to pay them, do it. There is nothing that will stop the "toe in water" faster than a fail on a bench or squat. Also, it would help to have someone around to make sure your form isn't collapsing once you are pushing yourself.....trust me, many a gym is full of guys squatting with their knees together. Don't join them
Step 3) Keep up the basics. Don't listen to bozos telling you that you need to do 40 exercises to get strong. If it is in a fitness magazine, it is probably BS. Most people need to minimize.....
Happy that you are seeing the light. Like I have said on here many times, heavy weights meeting testosterone does some pretty amazing things. You may be amazed at your progress.
"They now look to a single and splendid government of an aristocracy, founded on banking institutions, and moneyed incorporations under the guise and cloak of their favored branches of manufactures, commerce and navigation, riding and ruling over the plundered ploughman and beggared yeomanry." - Thomas Jefferson, 1826
