So after my workout I do shrugs with Db for isolation for rotator cuffs
EVO is right. Shrugs are for traps. Do some external rotation stuff. Use light DB (5lbs) or plates (2.5-5lbs) initially. You can also use bands to train at many different angles. Just 5 min. or so of rotator cuff work at the end of the workout will help keep your shoulders healthy.
As for single legged excercises im not confident enough for those.
That is why you should start doing them. They will help you learn better balance as well as make sure that you do not have one side getting stronger than the other. From an athletes standpoint the increased stability on one leg will only help as well.
So does that seem ok? Also i would do 5x5 for every excercise with 90 sec breaks to give me most hypertrophy possible.
Use the reps scheme that I put in the earlier post. It allows you to train power, hypertrophy, and strength in the same week.
DO NOT DO JUST 5X5 FOR EVERY EXERCISE.
Hypertrophy will come from training sets of 5 all the way through sets of 15 (for some even higher reps) so you do not want to neglect any rep range.
