Cable Curls are a good bicep exercise to get a great pump.
Obviously you can work your biceps with machines or free weights. There is a big difference in using dumbbells or cables.
With dumbbells the actual resistance of the weight changes through the range of motion. And at the top of the range of motion and bottom of the range of motion there is much less tension with dumbbells.
Actually many cable machines use cams that also change the resistance throughout the range of motion, but there is more of a constant tension when using the cables.
So the big difference between cable bicep curls and dumbbell bicep curls is the constant tension with cables. Because of the constant tension, there is a lot of effort needed at the top of the range of motion and this helps to create a great pump in the biceps.
Bicep curls with dumbbells are still a great exercise, but here are pictures of cable bicep curls.
Starting Position: Attach a straight bar to the bottom of a cable machine. Grasp the bar with your palms facing up.
Form: Exhale and curl the bar towards your chest. Hold for a brief second at the top and then slowly return to the starting position.
Personal Trainer Tips: Be mindful of your posture. Keep your core muscles tight to maintain proper form.
Move in a slow and controlled manner so that momentum does not take over.
