Girevoy sport is competitive kettlebell lifting. It's been a contested sport in Eastern Europe for years but has only relatively recently made its way to the US and other countries outside the Eastern Bloc. For the development of both strength and endurance the methods used by competitive lifters to prepare for these events are probably second to none. Training methods used by these athletes with just the kettlebell I believe take the place of many other forms of conditioning using other weights or training equipment.
The only events are the snatch using one kettlebell, the jerk using two and long cycle using two kettlebells as well but doing multiple clean and jerks. Each is contested for ten minutes. The goal is to perform as many lifts as possible. Below are some clips of events.
