To calculate the increase in potential energy, we can use the formula for gravitational potential energy which is:

PE = mgh

where:
PE is the potential energy,
m is the mass of the object,
g is the acceleration due to gravity, and
h is the height the object is lifted.

Given in the problem, we have:
m = 180 kg,
g = 9.8 m/s² (approximate value on the surface of the Earth), and
h = 1.95 m.

Substituting these values into the formula, we get:

PE = 180 kg * 9.8 m/s² * 1.95 m = 3438.2 Joules.

So, the increase in the potential energy of the barbell is 3438.2 Joules.
