Leg extension / inner & outer thigh machine
 

Hi everyone!
I have just started going to the gym and I was wondering if leg extension machine and the inner & outer thigh machine are OK for people who are genetically predisposed to develop varicose veins and who might already have problems with legs' heaviness etc. I am young (23 y.o) so understandably I don't have varicose veins but I don't like the feelings on my legs after using them. What do you think? I know I should see a doctor, but I would also like to know your opinion.
