In this brief excerpt, the speaker explains how to calculate the total load on a barbell for a heavy squat (four 25 kg plates per side plus a 20 kg bar, totaling about 220 kg). He then discusses how a “gato” – a person or device that jumps onto the bar – creates a destabilizing force, not because of its weight but because it shifts the lifter’s balance. The speaker notes that many athletes deliberately employ various instability techniques during training to increase difficulty or engage different muscles.
