When I do my standing tricep extension I use 80/90/100 and do 3x10. However, I get a sharp pain in my elbows when I get to the 100... I work through it but it worries me I'm doing something wrong or is there a different exercise that can be as effective. I like it because it uses all those extra muscles to keep your balance and grip etc. I lift heavy as I'm gaining and really only like to do 6 reps with heavier weight if I can complete 10 but afraid to go any higher until I figure this out. I'm 29 5'10" 195#
