Load the bar. Skip the math.
Type your target weight and Spotter shows the exact plates to slide on each side — on a barbell you can actually read.
225 lb
bar + plates per side
Greedy-loads the heaviest plates first from a standard gym set. If your target isn't reachable with whole plates, we show the closest load and the leftover.
Spotter builds the whole session around you — sets, weights, and progressions that adapt every workout. Free.
