How to Do ISO Curls with Resistance Tube
ISO curls differ from regular biceps curls in that each arm is lifted separately. This biceps exercise uses a resistance tube, so you can do it almost anywhere.
Assume start position as shown by placing the arch of your left foot on the resistance tube.
Hold left arm at a 90 degree angle while curling with the right arm.
Perform one set of 12 to 15 with the right, and then repeat on the left.
