Unless you intend to get a pretty serious set-up at home, I'd recommend joining a gym. The most important exercise for adding mass and a great lower body strength builder - squats - are going to require a barbell and squat rack which would be hella awkward to have at home.
For general conditioning, circuits sessions are a great way to increase your fitness whilst also being good for getting stronger.
Whatever you do, don't do Starting Strength!
Do you mean gridiron or wendyball?
Wendyball by the looks of his avatar.
I wouldn't be doing plyo's at home, less you wanna be throwing medicine balls through the walls. that stuff be better at a gym.
Are we talking american football? At 67kgs and 6ft? You goin down unless you hit mcdonalds man
Think he is talking of fag ball by the look of it.
As long as you train hard, spend hours on conditioning, balance and technique drills then dive on you face when someone comes within a meter like a ****** you will be fine in the "Beautiful game"
