This version of the shoulder
press resembles a "strongman" type of movement
where you're treating the dumbell like an odd-shaped object
rather than a dumbell.
It a front-delt accentuated
type of exercise, similar to an Arnold Press but without
rotating elbows around because they're set on the dumbell
(you'll see what I mean).
First, you'll need a moderate
to heavy dumbell (just one). Set it on the floor. Reach
down and grab it with both hands.
Lift the dumbell to your chest
then lean back so you're supporting the dumbell on your
chest.
Now change your grip from
on the handle to putting your palms under the dumbell plates
so your fingers are gripping the sides of the plates the
dumbell is being held vertically.
Press directly up as high
as you can.
Lower down then press again.
Simple from there - it's just a straight-up shoulder press
using a different way of holding the dumbell.
When you're done with the
set, lean back and rest it on your chest again. Grab the
handles then set it back down on the ground.
This is a nice chance of pace
from regular shoulder pressing. The closer grip hits the
front delts nicely.
