Blast from the past …
Stefan Botev with a 320kg Squat.
This happened in the 1995 Worlds training hall. Later in the comp he did a 190kg Snatch and 245 Clean & Jerk for 3rd place in the total.
Update 24.02.2016: Ironmind uploaded the full training hall video! Here he lifts a 190kg Snatch at 23:23, a 250kg Clean at 33:15 and a 320kg Squat at 37:00.
