i started with a home gym, barbells/dumbells and an all in one pec fly/lat pulldown/smith/pullups etc.
I lost motivation so quickly, and got bored of it. i didnt know if i was on the right track, if my nutrition was in check (hell no it wasnt) and if my form was right (LOL) and whether or not i had the right routine going (i dont even wanna think about that). I would highly highly highly recommend joining a gym. if you pay for it yourself, you WILL make use of it (if youre anything like me), and if you sign up for a long time (say, a year) then you WILL achieve your goals. you wont give up half way through. and if you have to physically leave the house to do it, you'll put in a lot more effort than if you just had to go into the garage to work out.
If you dont really think you need all that, cos youre just getting started, you will kick yourself in the face in 2 years' time, cos you'll feel like you wasted all the previous time working out (2 years is a long time to lose).
which suburb do you live in dunherro? I might be able to recommend some good places (maybe, depending on where you live)
