<human>:  John can front squat 80% as much as he back squats. He used to back squat 200 kg but increased that by 50 kg. He can do a triple equal to 90% of the amount he front squats. How much weight will he move if he does three triples?
<bot>: How much did John increase his back squat? ** He increased his back squat to 200+50=<<200+50=250>>250 kg
How much does John front squat? ** That means his front squat is 250*.8=<<250*.8=200>>200 kg
How much weight will John move if he does three triels? ** So he can do a triple with 200*.9=<<200*.9=180>>180 kg
How much weight will John move if he does three triples? ** So he moves 180*3 = <<180*3=540>>540 kg if he does three triples
