Cable biceps exercises

What does a cable give you that dumbbells do not?

Continuous tension. In a dumbbell curl the weight ends up hanging over your elbow at the top and the biceps gets a few tenths of a second of relief on every rep. On a cable the line pulls your arm back down wherever it is in the range, so the muscle never gets that break - hence the pumped feeling that a cable set is known for.

The second advantage is loading. Plates step up a few kilos at a time and you change them with one hand, with no putting a pair down and hunting for the next one. For drop sets, or a finisher at the end of a session, that matters.

How do you set the station up?

Clip the handle on the lowest hole - the lower it sits, the more vertically the cable runs and the cleaner the movement is. Stand close enough that the cable is already under tension with your arm straight, but not so close that the plates clank together at the bottom.

The single-arm version is worth using even if you normally curl with both hands: it lets your wrist rotate freely and frees the other hand to check whether your elbow is really staying put. A preacher bench adds the same insurance mechanically - the upper arm lies on the pad and swinging is off the table.
