To me, kettlebells are a hipster trend.

Bw: push ups, pull ups, crunches, supermans, squats, calf-raises, planks, wallsits, HPUs or easier variations

or

Weights: bench, rows, deadlifts, squats, OHP (google 5x5), pull ups, calf raises

+

run, bike, or swim Just something to keep in mind as minimum.

They've been used for centuries in one form or another and are a fantastic tool, lauded even by world-record holders in the deadlift.

No, they are not, if you don't have access to a bench and barbells, you can pretty much do all exercises and more with a couple of kettlebells. I use a 20 and 35 pound one. Btw, Kettlebells have been around for a long time in Russia.
