I use dumbells every now and then but mostly barbell. Now today, i decided to push myself and see what I could do. I did flat dumbell presses for my 2nd exercise so I was already slightly fatiged. Got to 4th set with 130 pounders and STILL did 10 reps! So yeah, im kinda happy. My gym goes up to 150lbs dumbells so next week im gonna start with 120s and go to 150s on 4th set I think.
Also few days ago I decided to try barbell military presses behind the neck. Ive only ever done in front. ( I can do 300lbs for reps) I was surprized to get to 275lbs behind the neck for 5 reps on 4th set!
Next month I plan to try 315lbs barbell military for 3 reps video tapped.
