Here is my youtube channel.
There are sets with 16kg (25rpm for 8 min). A set with a 24kg where I did 12rpm, and a set with a 20kg (15rpm I think).
My technique is actually better in the 24kg and 20kg set. When I was snatching all 16kg, I was pushing pace to hit 240 reps in 10 min (Did it at home where it doesn't count but never in a comp..my comp best was 221).
