in 3 powerlifting moves.
Yes, three movements determined long ago as the best to gauge an individual's overall strength and power. Besides that which is tested with squat, bench press and deadlift, what else is there of relevance? Biceps? Of no relative importance, really. Calves, in their capacity to contract from a fully-stretched position? And besides, these muscles play a supporting role in the three lifts, anyway.
No true strength athlete/expert will ever give a rat's ass about what someone can cable fly, lat pulldown/chin, biceps curl, calf press, leg press, leg extension, lateral raise, etc.
