While you might not feel tons of resistance straight away, your biceps will be burning after 30 seconds, especially if you do this drill unilaterally. If you have absolutely no equipment but still want to build your biceps, then you can do curls with your door in an isometric fashion.

This would effectively double the resistance without you having to add actual weights around your legs and ankles. To increase the challenge still further, you could wrap the towel around your leg and then grab both ends of the towel with the same hand. So if you've been skipping those squats, then you might want to wear some ankle weights to increase the resistance. The heavier that your leg is, the harder this exercise will feel. From there, you just lift your leg as high as you can so that your biceps are contracted. To perform this underrated exercise, you simply grab each end of a towel and then wrap the towel around the back of your leg. Isometric towel holds are a type of towel curl that you can do virtually anywhere (even in the shower if you want). Repeat this process two more times so that each arm has done 10 curls and two lots of 5-second holds.Switch over so that the arm that was working isometrically is now doing 5 curls.Immediately perform 5 regular (full range of motion) curls with your other arm.Curl one weight up-so that your elbow is at a 90-degree angle-and hold it there.This ultimately helps you to sculpt a more symmetrical physique. Moreover, because you're performing this isometric bicep exercise with dumbbells, you have less chance of developing muscular imbalances (than if you were using a barbell) because each arm has to work independently. So as you can see, your biceps are always under some kind of tension. Then you switch tasks so that the arm that was working isometrically is now performing normal curls.

Yet, static arm curls are also effective for bodybuilders because they really blast your biceps.Įssentially, you hold one dumbbell isometrically while performing regular curls with the other weight. Therefore, these curls are the ideal stepping stone between isometric and dynamic training, which is ideal if you're recovering from an injury. Static arm curls give your biceps the best of both worlds challenging isometrics and muscle-building eccentric loading.
