Ivan Denisov is one of the greatest kettlebell lifters of all time, some would argue he is THE greatest. Denisov holds the absolute world records for both kettlebell sport events (biathlon and long cycle) and has recently been awarded the highest rank possible in kettlebell sport: Honoured Master of Sport.
At a training camp at the Ice Chamber in San Francisco in February this year, Denisov set a mind boggling world record by snatching the 24kg kettlebell 730 times with one hand switch - a feat that took 35 minutes of continuous lifting.
This incredible world record is even more impressive given that Denisov didn't train specifically for it, he just gave it a go on the day.
You can see the whole set here. Even if you don't watch it till the end it's worth skipping to the last couple of minutes to see how even after 35 mins of lifting he maintains good form and stops the kettlebell perfectly still in overhead lockout. That is professionalism!
History in the making.
