You can really manipulate a weight by decreasing your leverages, as I try to show in the examples provided. For example, doing a pistol holding the weight in the front rack of the opposite foot, changing where you grip the kettlebell to offset the weight, or using a straight arm for rows.
Straight arm work such as crucifixes, flies in multiple directions (standing or supine) or raises in multiple directions can build unreal strength that is typically only found in gymnast ring experts….those guys are stroooong.
When I had a 20 kg kettlebell, I used to play around by practicing disadvantaged movements, such as pressing the ketttlebell straight in front of me from standing (as opposed to overhead). Okay that’s easy? Do it with one arm….
And I didn’t even mention the obvious weighted moves like dips, pull-ups with the kettlebell attached.
Get creative.
Bodyweight training is unlimited.
Adding a kettlebell, despite being “only” 16 kgs can open a new galaxy of options.
