Exercise expends energy.

yes it does
A shuttle launch does not create energy. Instead, it expends stored energy from its fuel sources to propel the shuttle into space.
Active transport expends energy to move substances against a concentration gradient.

A bicycle carries kinetic energy when it is in motion. The kinetic energy comes from the rider's pedaling efforts and is stored in the motion of the bicycle and rider.
In a bicycle, the energy transformation involves converting the chemical energy stored in the body into mechanical energy by pedaling. This mechanical energy is then transferred to the wheels, where it is further transformed into kinetic energy to propel the bicycle forward.
The output of a bicycle generator is electricity, which is generated by pedaling the bicycle to power a generator that converts mechanical energy into electrical energy.
The one who works the hardest.
The energy transformation in a bicycle is primarily mechanical energy. When the rider pedals, their muscle energy is converted into kinetic energy to move the bicycle forward. The mechanical energy is also used to overcome frictional forces like air resistance and rolling resistance.
