Biceps Curl.

No swing from the hips.

A barbell curl quickly becomes a whole-body exercise: a little swing from the hips, a little help from the shoulders, and the biceps get away with less than you think. Here the upper arm rests on an angled pad that locks the elbow, so the only joint allowed to move is the one you came for. The 60 kg stack sounds modest until you have tried it without the swing. The machine measures 1457 × 1221 mm, is 1543 mm high and weighs 188 kg. Sixty kilos is more than enough when nothing helps out.
