I have been lucky enough in my life never to exceed 180... and that was after surgery from a double hernia when I had to sit on my ass and do nothing for 8 weeks.
Pretty fit guy just from the work I do, but I also do some moderate weight training and such just to keep my boyish figure :yeh:
A forum I use is bodybuilding.com, which has a lot of videos showing the proper technique for exercises, either with free weights, machines or body weight exercises. One of the main keys is not over doing it the first few weeks, to prevent any injuries which would slow your progress, or completely stop it, depending on the injury.
One thing I did learn is to set smaller goals, closer together. By this I mean set a weight you want to be at in 2 weeks, whether lifting it, or losing it. This makes your goals much easier to obtain, which is a big psychological edge.
Good Luck guys, and I will be here cheering you on !!!!
