Don't agree with his comments on not doing sport specific training, also if lifting a sandbag was so specific why are most labourer types not in great shape?
It's a training tool like anything else but not special.
As I wrote before we ran up fire escapes with a sand bag on our shoulders for strength & endurance.
Could I have got this from high rep squats, certainly.
We didn't even have a barbell to use but we got the job done with a sandbag.
He said if your goal was a gymnast physique (big arms and shoulders?) and not gymnastics you be better off to train like a bodybuilder than doing gymnastics.
Did I miss something he said?
"When pure muscle building is the goal..." i.e. appearance, do muscle building exercises, not sports.
There are too many fat American football players to argue with that.
Obviously, as far as skill training you get better at what you do.
To get better at jumping you have to jump. Practicing guitar probably won't improve your vertical.
Will lifting barbells or sandbags make you a better tennis player? Not hardly as much as playing tennis will.
All other things being equal, being stronger helps in most things.
I'm surprised you would say such a thing about laborers though, Donny.
Most laborer types are in great shape. As long as they are actually doing the labor and not goofing off.
"Shape" in this case being defined as work capacity and not as appearance.
They would as the saying goes "work you into the ground".
I'm talking about guys who are movers, ditch diggers, longshoremen, etc. Not forklift drivers.
You must know that a bodybuilding type appearance does not indicate physical health and work capacity.
Ever done work as a professional mover or a ditch digger? Try working a hand shovel for 10 hours a day or moving heavy furniture, boxes, and appliances likewise.
It's brutal. Eventually, you do acclimate to such rigorous work. It's much harder than hitting the gym for an hour and a half 3-5 times a week.
Work like that would kill your pretty boy drugged up bodybuilder.
He has another video where he talks about "farmer strength" and says lifting heavy free weights, odd objects, stones, sandbags all develop it.
