the heavy ones are these from cam as thick have a very dense rubber grip on them,you will get used to the weight in a bit of time you have to build up the hand and wrist muscles.I use all weight of machines and i have small hands -just dont try to do a 4 no stop session at first with the heavy liner and hurt your hands.
