Tim Egerton of Sprint Strong, had pointed to this video and noted:
Interestingly, a new technique seems to be adopted here whereby he performed a 'pre-lift' before his actual attempt at performing the Snatch. This is legal so long as the bar does not break the line of the knees. I expect this 'pre-lift' will have provided a slight potentiation effect.
Is anyone aware of this technique having been adopted previously? I wonder if it will become commonplace now.
