Finally failed on my squats today. Started again at 3x6x100kg at the end of January. Managed to get up to 122.5 which i repeated last week as i struggled. Tried to give 125 a go today and failed on the 3rd rep (of 5-6). Dropped the weight for 2nd/3rd sets back to 120 and got through it just although was pretty fatigued. Going to reset it back down to 115 and build my way up again. Might even give smolov a try in 5-6 weeks time. Also i've been doing a 20 rep set as 4th workset and have got that from 12-14x80kg in Jan to 20x90kg today (still pushed through quite easily even though i failed earlier in workout). I will keep slowly increasing the weight on this set as i don't feel the need to drop this one back. Quite happy with the progress as i was previously stuck around 100-102 for ages last year.
