great to hear that, there was 1 time i was feeling good, hence i performed 3 set of 20reps, the latic acid burn is interesting.. and the time racked the bar, i terus jatuh and lying lol. the good thing i like about 20reps is, it really helps alot in mental toughness, whenever i squat heavy, i always tell myself i can do this weight for 20reps, for sure i can do greater weight with lesser reps!
