It's purely a weight position and distribution difference.
Thanks guys. Both of your answers confirmed my prior thoughts about the merits of KB training.
bump!
i thought i would chime in here briefly as ive been using the gyria (kbs) for close to 7 yrs. Some history:
Pavel Tsatsouline was the bloke responsible for introducing kb's to the west (US) back in the late 90s. But he advocated an approach which he termed "Hard Style" meaning that he used the bells for inducing extreme tension in ballistic shock movements such as swings, clean & jerks and snatches as well as extreme tension using grinding movements like the so called military presses. It certainly got you results very quickly but you had to be very careful not to burn out. He also advocated crazy eclectic type lifts like bent presses, windmills, arm bars etc etc.
But the kettlebell as originally used in Russia was NOT used for extreme tension and grinding presses, they were and are used for developing work capacity ie strength endurance. The training used for developing work capacity is scientifically documented in old Soviet training manuals now being translated and published on the web by a kettlebell enthusiast (an aneathetist) visit his blog here
Girevoy Sport after 40In a nutshell, kettlebells are used in Girevoy Sport for 10min rounds, most repetitions wins in several weight classes and Categories:
Category A: Biathlon
- Double kettlebell Jerk ie 2x24kg or 2x32kg for 10mins. I think the world record for 2x32kg in 10mins is around 150 reps or so but forget the correct number. I'm sure you can appreciate the type of effort this requires!
- Snatch
Single 24kg or 32kg kb snatching for reps in 10mins with one hand swtich allowed. World record with the 32kg is about 190 or so.
Category B: Long Cycle Clean and Jerk
- 2 x24kg or 2x 32kg but this time cleaning the bells in the rack before jerking overhead. Exremely tough!
Category C: Juggling
Men use a single 16kg kb, women an 8kg to juggle from hand to hand by flipping turning using footwork, spinning etc done for time. Develops amazing hand/eye coordination and an incredible grip.
The sport and the training develops pretty much super humans who are very lean and very fit and are some of the most strongest men and women you can find. The only way to survive in the sport is by relaxing and not to generate excess tension and hence sometimes refered to as a 'fluid' style.
So the difference between kbs and dbs is really easy - the design because you cannot use the db for Girevoy sport. Imagine how uncomfortable it would be to rack say 2x24kg dumbbells for 10mins?
On a personal note, I only train in girevoy sport (GS) and has been the best thing i have ever done.
