Yeah that would probably lead to overtraining... you have 15 sets + dips and push-ups for chest, 21 sets for legs, 19 for back, 11 for shoulders, 8+ isolation exercises for biceps. Usually the line between a good workout is 6-9 working sets per body part.
You might want to bring your
chest exercises down to 3 per body part. Alternate dips and decline bench, and get rid of push-ups.
Triceps look good...
Legs down to 2 (a calf workout won't hurt doing 3 sets since it only gets minimal exercise during other workouts)... you could probably get rid of machine squats since you already do normal squats.
For your back, I'm assuming for back pulls you mean low seated pulley rows? You should definetly add deadlifts and maybe alternate them with power cleans. Probably bring your working sets down to 2 per exercise and maybe get rid of something like T-Bar rows if you incorporate deadlifts/power cleans into your workout.
For biceps, BB and DB curls are good, maybe try seated or incline DB curls? I'd definetly up the weight on DB curls if you're doing 20 reps per set. As far as isolation exercises, most biceps exercises are isolation exercises... I'd just add hammer curls and throw out the other exercises b/c in my opinion BB, DB, and Hammer curls are all you need for you biceps. I'd probably go 2 sets BB, 3 sets DB w/ perfect form, 2 sets hammer curls.
*As far as pull-ups and chin-ups are concerned, I'm guessing you're talking about different grips on the bar (supine and pronate)... I would just do one grip, which ever you want. Chin-ups/Pull-ups are a great workout for the back and biceps (especially supine grip for biceps)
For your
shoulder exercises, make sure you hit all 3 heads of the shoulder... anterior (front) deltoid, lateral (side) deltoid, and posterior (rear) deltoid. Military press will hit the front deltoid, I wouldn't do both DB and BB military press, maybe alternate them every workout. For your side deltoid, nothing beats upright rows. For rear deltoids, a good workout is DB Row (with elbow out).
As for traps... shoulder shrugs are the best.
As for reps... what are your goals? If you're going for strength and endurance, high reps with a low weight will yield results (8-12 reps). If you're looking for muscle mass, low reps with high weight will get you bulkier (4-8 reps).
