Give the step-by-step reasoning process and then the final answer. 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?
He increased his back squat to 200 + 50 = 250 kg. That means his front squat is 250 * .8 = 200 kg. So he can do a triple with 200 * .9 = 180 kg. So he moves 180 * 3 = 540 kg if he does three triples.
The final answer: 540.
