The most essential bicep exercise is the curl; here the cable machine adds an additional degree of dynamic resistance for both bicep and core.
Set a single handle on a cable machine in the low position and stand facing away from the machine with the cable in one hand, palm up.
- From the starting position, bend your elbow on the arm holding the cable and bring your palm toward your shoulder in a curl. Keep your upper arm stable as you do so.
- As you curl, keep a tall posture with shoulders back and head up. As you start each curl, keep your belly button in to fire your lower abs. This will train your core to stabilize before lifting movements.
- When you have brought your hand as close as you can to your shoulder, reverse your motion and slowly lower your hand, straightening the elbow.
- Do a set with one arm, then switch hands and do the next set with the other arm.
