An EMG-Optimized Routine
There is of course a myriad of ways of
combining the individual exercises, my personal recommendation for overall
deltoid development and rotator cuff strength (based on EMG
measures) would yet be as follows...
  1. Military Press - BB or DB seated, 6-8 reps
  2. Lateral raise - DB elbow-flexion <15°(!), 10-12 reps
  3. Reverse fly - machine or DB, internal rotation, 10-12 reps
  4. External DB rotations - lying on the floor, 12-15 reps

An EMG-optimized routine There is of course a myriad of ways of combining the individual exercises, my personal recommendation for overall leg development (based on EMG measures) would yet be as follows*:
  1. Squats - to parallel (70°), 6-10 reps
  2. Hack squats - to 90°, 8-12 reps
  3. Leg curls - peak contract. or partials, 10-12 reps Superset:
  4. Donkey calf raise - peak contract., 12 reps
  5. Seated calf raise - partials, 12 reps Optional
  6. Adductor machine - 12-15 reps
  7. Abductor machine - 12-15 reps
You may notice that I do not make volume (i.e. set) recommendations. This is due to the fact that I found that everyone has to find what works best for him / her in terms of optimal volume and training frequency. This may also change over time / according to lifestyle factors / nutrition and supplementation.

An EMG-optimized routine

There is of course a myriad of ways of combining the individual exercises, my personal recommendation for overall core development (based on EMG measures) would yet be as follows*:

  1. Crunches < 20 reps; vary arm / hand position or add weight + peak contractions to build intensity without going past max. 25 reps
  2. Leg raises < 15 reps; vary according to exercise tip #1; do at least one of your sets with your legs / torso rotating sideways, alternate left and right
  3. Deadlift variety 10-12 controlled reps; select the deadlift variety you feel isolates your lower back best
* "<" indicates that you should not be able to
perform another rep with perfect form
You may alternate that with:
  1. Kneeling cable crunch < 15 reps; add weight whenever possible
  2. Side bends < 15 reps; add weight if necessary, be cautious not to
    bend over or go into hyperlordosis
  3. Hyperextensions** < 12 reps, with proper form + peak
    contraction; add weight if necessary

An EMG-optimized routine There is of course a myriad of ways of combining the individual exercises, my personal recommendation for impressive back development (based on EMG data) would yet be as follows:
  1. Pull ups to the neck - for lat development + all those hidden stabilizing muscles a full body movement such as the pull up activates (5-10 reps / use additional weight or rest-pause if you can do more / less)
  2. Narrow underhand grip pull-down to the sternum (in contracted position pull elbows back as much as possible) - to fully exhaust the lats (8-12 reps)
  3. DB shrugs (use peak contractions) - for upper trap development (10-12 reps) Super Set = go from 4 to 5 without rest, rest after 5, repeat
  4. Reverse fly 90° (preferably on a machine like the one in image 4) - for mid trap development (10-12 reps)
  5. DB reverse fly 110° (use light weights, feel the burn!) - for lower trap development (do to failure, up the weight if you can do 15+)

  1. Barbell curls - straight bar, supinated shoulder wide grip; explosive
    concentric, controlled excentric movements, high loads, 6-8 reps
  2. Scott curls - campered bar, supinated narraw grip; full stretch at
    the bottom; medium load, 8-10 reps
  3. Dumbbell concentration curls - switch between supinated and hammer
    grip; medium load or supramaximal load (use sparingly) 10 reps (use other arm
    for assistance, if needed)

  1. Decline Bench Press (BB) - for overall chest development + strength
    (5-10 reps)
  2. Incline Bench Press at +45° (DB) - to emphasize upper chest (8-12
    reps)
  3. Cable Cross (making sure to actually cross the cables before your
    torso) - to get a stretch and peak contractions (12-15 reps)
  4. Bodyweight dips - to wear the muscle out (3 sets to failure)

When all is said and done, we are thus - once again left with the
ultimately valuable insight that it's not really worth to overthink the matter
of "optimal muscle stimulation". The time you waste pondering the pros and cons
of certain grip widths, of which you don't even know if their effects on the
electromygraphical activation does even relate to their mass- and/or
strength-building qualities, would be better spend actually doing lat pulls, or
- even better - pull ups.
