Insane Shoulder Workout
DUMBBELL MILITARY PRESS - 4 DROP-SETS: Just like a regular military press, but with dumbbells. Try to arch your back and bend your legs as little as possible to really isolate your shoulders.
UPRIGHT ROW - 4 DROP SETS: Hold the dumbbells in front of you, and row them upwards towards you head. Try to avoid SWINGING the weight up with your back -- stand as straight as possible, and move the weight upwards with your shoulders. I didn't have any lighter dumbbells, but as I said in the video usually I will use a lighter weight than this and use my back less when doing this.
BENT OVER SIDE LATERAL - 4 DROP SETS: Turn the dumbbells OUTWARDS to hit the back of your shoulders. Keep your legs as straight as possible, and bend at the waist -- don't round your back. You should feel a STRETCH in your hamstrings in this bent over position. You'll be very tired at this point...but again, try to isolate your shoulders as much as possible and avoid excess swinging the weight with your back.
HOW TO DO DROP-SETS: To do the drop-sets, do a set of 12, then rest 8 seconds. Then IMMEDIATELY start on your next set. Aim for sets of 12-8-6-4, but it's OK if you do a few more or less reps than this. Just do as many as you can on each drop, and you'll be good. The most important key to drop-sets is that you start on the next set IMMEDIATELY after the 8 seconds are up. It is tempting to rest more, but don't do it! Your drop-sets will be much more effective if you're strict with your rest.
HOW BEGINNERS DO THIS WORKOUT: Do four drop-sets of each exercise like I showed, this equals one round. After the round rest as much as you need to in order to feel fully recovered, then do one more round.
HOW ADVANCED GUYS DO THIS WORKOUT: Just like beginners, except do FOUR rounds. You will really be feeling your shoulders after this!
