Excellent quality at a great price. Fast delivery. The spring clips make it a breeze to instantly change plates. Great for bicep curls, reverse curls, preacher curls, triceps, shoulder press front, and behind neck, upright row, bench press, even light squats at a pinch (although bar needs a little padding). Closed grip, wide grip. Options only limited by your imagination. Filled an important gap in my home gym weight training as I have been having to make do with Body Power pro style dumbells. Body Power weights 1" fit the curl bar no problem.
