Starting out with Kettlebells

Hi Guys, so for a few years I've owned some kettlebells (10kg, 14kg, 28kg) I used them mostly for training pullups at home - their easier to store and move around and clip to a weight belt for pullups.

Recently (about 3 months) I've been on a quest to get huge forearms and have been using kettlebells for different forearm exercises but I started to do swings as well. For my swings I've been doing 5 sets of 20 with my 28kg bell, but I'd like to follow a proper structured workout that builds explosive power, build a solid core and buns of steel, and hopefully my shoulders as well.

Can anyone simpify it for me and tell me what actually works and to do? there's far too many "This is the only workout you need with one kettlebell!" workouts out there

For
