Thanks for the help gentlemen. I'm going to check into some equipment but I don't want it to get cost prohibitive...although I do have three boys and perhaps if I purchase the stuff now it will pay off in the future? The gym I train at is pure shit, they don't have much of what I need but honestly it's the best show in the area.
As for the recommendation of kettlebell deadlifts / swings...I do have access to light kettlebells but do you really think that's close enough to translate to a barbell?
I do live near a quarry so I have plenty of access to rocks but I'm not a big fan of that idea just because it's not controlled enough. I think it'd be really easy to get fucked up trying to lift rocks etc...then I'll never hear the end of it from momma-bear.
The 5 lbs. bumpers might be the hot ticket. Though 45 + 10 = 55 and we're already talking 50% bodyweight for this kid...and I'm not trying to be too conservative here, I mean I'm 230ish and I could probably deadlift 115 all day long, but is 50% bodyweight too much for a kid?
