The weight of a 115kg barbell is constant. The lifter's weight, however, will vary. If the lifter weighs less than 115kg, the barbell will be heavier relative to their weight. If the lifter weighs more than 115kg, the barbell will be lighter relative to their weight.
The forces acting on the weight lifter and the weights are balanced when the weight lifter is holding the weights stationary. The force exerted by the weight lifter is equal and opposite to the force of gravity acting on the weights.
At the beginning of the lift, the lifter's force is greater than the weight of the barbell to overcome inertia and initiate movement. During the middle of the lift, the lifter's force is equal to the weight of the barbell to maintain constant velocity. Towards the end of the lift, the lifter's force is less than the weight of the barbell due to deceleration and control.
The Doctor has a sister that is a World Champion weight lifter.
While just holding the weight on his shoulder, the weight lifter does no work! For work to be done, the mass must be moved through a distance … No Movement, No Work! (but don't tell that to a weight lifter …)

A "brawny" man is one that is well built and well muscled - so a weight lifter's gym.
Weight training will build more muscle in a shorter time frame.

If the dumbbell does not move, then the work done by the weight lifter is zero. This is because work is defined as force applied over a distance in the direction of the force, and if there is no movement, no work is done.
