This document discusses replacing a large water jug with two smaller jugs to make it easier for gym users to access water. The smaller jugs require less effort to lift and are in a more ergonomic position. Additionally, the jugs were made transparent so users can easily see the water level and know when to refill them. It suggests reversing the positions of the jugs could provide more convenient access to the lighter one.

1. Before
This water jug is too heavy for
ladies. It might help to have two or
more smaller water jugs.
After
The smaller jug is closer to the user thus
requiring less effort in lifting the jug from an
otherwise less ergonomic position.
The jugs have been replaced to be transparent to
facilitate observation of the water level that needs to
be replaced in the event that the water has reached a
sub-optimal level.
Positions of the two jugs could be
reversed to provide convenience to
access the lighter water jug for
members.
