Humans are movement generalists of the animal kingdom. Neither the strongest nor the fastest but one of the most adaptable and capable. Our bodies are designed for work; lifting and carrying awkward shaped objects seems like a fundamental human movement to me.
If you are just starting out training and don’t know a kettle bell from a kettle ball, then some GPP training is the place to start. For the increasing number of people who have sedentary jobs there is value in just doing some general physical work. If the most strenuous thing you do in your job is walk from your desk to the coffee machine then try replicating some manual labour in the gym.
This circuit is:
Clean and press from the ground alternating arms
(A dumbbell could be used instead of a kettlebell.)
60 seconds work, 15 seconds rest, per station for 6 sets
