yeah lockout is not good with any lift. i have a hyperextended elbow. my avi doesn't show it, but my left elbow goes to maybe 190 degrees. lockout on dips would take me out of the gym for awhile.
i work my chest/shoulders together, twice a week. here's tuesday's routine :
chest/shoulders
4 sets of 5 as supersets (strength)
bench press 205/210/215/210 (5-10 lb increase on 3 sets)
military press 155/160/165/165 (10 pound gain for two sets)
incline bench 175/175/180/180 (up 5 lbs for two)
DB front delt raises 30/35/35/30 (up 5 lbs for two as well)
butterfly machine 220/220/220/220 (machine maxed still)
DB side delt raises 25/30/30/30 (no change)
chest dips 40/40/40/40 (nothing)
rear delt DB raises 25/25/25/25 (nothing)
smith upright row 90/100/100/100 (up 10 lbs for three. tried 105 and noticed my calves moving)
wide grip pullovers 80/80/80/80
here's fridays :
chest/shoulders
4 sets of 10 as supersets (time under tension)
DB bench press 55/60/60/60 (up 10 pounds for two, PR with the 60's. had to rest pause last set to get 10 reps)
DB arnold press 35/35/40/40 (up 5 lbs for two sets)
DB incline bench 50/50/55/55 (up 10 pounds for two again - WTF?)
cable front delt raises 25/30/30/30 (up 5 lbs for three)
decline barbell bench 225/235/235/235 (up 10 lbs for three)
cable side delt raises 30/30/30/30 (nada)
cable crossovers 65/65/65/65 (happy just to make it through this)
wide grip pullovers 50/50/60/60 (up 10 lbs for two)
cable upright rows 70/80/80/80 (up 10 lbs for three)
cable rear delt raises 20/20/20/25 (failure on 25 on rep 8)
cut/pasted from my log. guestimating weights for cables (its not always what the machine says), and i'm assuming the smith machine weighs 10 pounds unweighted.
going from military press to incline bench really beats the front delts up

. probably a silly routine, but i like it.
