Sure you're only 50...LOL...J/K. Yes I'll agree with mikes, that side tricep pose is stellar! I think that your arms look great and with that said....why yes I think I would still like the "Xpose" arm workout. Take care.
Dude I always am looking at new workouts and would be willing to try it!! You looked great in your pics dude and keep up the good work!! Your truly insipring I hope I am in your shape when I am your age! Also your arms are pretty freaky dude
