[FEATURE] Exercise swapping

[BenGWeeks]

Is your feature request related to a problem?

When a machine is in use, it can be frustrating to try and think of an alternative exercise to attack the same muscle.

Describe the solution you'd like

• As a gym goer, I would like to easily swap an exercise for similar exercises that attack the same muscle group

Describe alternatives you've considered

• The solution must know what muscle groups a particular exercise targets

Priority

Nice to have

Additional context

FitBod is pretty good at this (swipe the exercise left and presented with alternatives)
