They have both but 95% are plate loaded.

Actually, you move the " arms " that hold the plates in a " football-specific "

manner (Hammer's terms) that is in an upward or diagonal path. The arms

start at approximately chest height and the lift is finished above the head

as if blocking and pushing as a down lineman.

Hammer claims you can add enough load to " overcome the issues of finding a

proper weight to accelerate " .

It's a bunch of crap.

Joe,

Having trouble understanding this last sentence. Can you clarify what is

meant by overcoming issues of finding a proper weight to accelerate?

Thanks,

Josh asks: Joe, do you mean finding the maximal weight that will still allow

you to move explosively - however that is defined here? Do we still gain

benefit by attempting to lift a weight explosively (attempt to be fast) even

if we cannot actually move the weight quickly? I tend to believe we do gain

benefit, any thoughts?

I have used the Hammer Jammer. I supposed its OK for training explosively on

an incline, though medballs and push presses (albeit a different angle) are

probably more realistic in most budgets

This is a classic example of the specificity concept being misinterpreted as

simulation. The fact that this exercise follows an upward/diagonal path is

relatively insignificant if the machine provides guided resistance, and the

exercise can be done without applying forces at the same RFD or power levels as

the sport movement.

The resistance arms on the jammer can be pushed at the wrong angle, and will

still track in one predetermined direction. This can be done at impulse or

power output that does not correspond to a lineman executing a block. In terms

of mechanics, the olympic-style jerk is more specific to these movements

despite the difference in appearance (e.g. vertical rather than diagonal

movement path).
