Regan Grimes Shoulder Workout for Mass

Broad, powerful shoulders help fill out a t-shirt, give the illusion of a smaller waist, and help you achieve the vaunted v-taper, but most guys often struggle with building massive delts for a variety of reasons.



Far and away the top three reasons are people struggle to grow their delts is:


  • They don’t train hard enough

    Simply put, the vast majority of people lack the ability to really push themselves hard enough in the gym to make progress. Now, we’re not saying you have to verge on puking every time you come face-to-face with the iron, but you do need to struggle and come pretty close to failure in your lifts.

    If you can talk on the phone while you’re lifting weights, or if you feel like you can train for another couple of hours after your training session is over, then you aren’t training hard enough.

  • They use piss-poor form

    Lifting heavy ass weights looks impressive, but if you’re doing quarter-reps, using a lot of body english, or letting gravity do all of the work during the eccentric phase of the lift, you’re wasting your time. Using poor form removes a considerable amount of tension from your muscles, which means that they are not performing as much work as you think they are.

    You’ll make far better muscle and strength gains lifting a lighter weight with perfect form and control than you will jerking, flailing, and half-repping a heavier weight.

  • They don’t increase the amount of weight their lifting

    If there’s one rule that dictates muscle growth it is this -- if you are not adding weight to the bar over time, you aren’t getting bigger.

    Muscles only grow in response to being challenged to lift more weight for more reps. It’s as simple as that.

    In other words, if you’re still pressing the same amount of weight for the same amount of reps 6 months from now that you currently are, don’t expect to have grown much at all in size or strength.


Primeval Labs Athlete and IFBB Pro Regan Grimes is one of the hottest names in professional bodybuilding these days, widely regarded for his broad, massive shoulders.


We followed along with Regan during his recent shoulder training workout with fellow IFBB Pro Stanimal. We also got some insider training tips to help those of you who struggle to put on size.

Regan Grimes Shoulder Training Tips for Mass


With that said, let’s take a look at some more shoulder training tips from the man himself, Regan Grimes.

Seated Dumbbell Shoulder Press

When lowering the dumbbells, try to keep the elbows from dropping below parallel to the ground. This helps maintain tension on the delts for longer. When you allow the elbows to drop below parallel, as may people do when performing the overhead press, it removes tension from the deltoid.

Side Lateral Raise

The two big keys to any side lateral raise, whether it be with cables, dumbbells, kettlebells, or resistance bands are:


  • Lead with the elbow
    It’s quite common to see lifters perform lateral raises leading the movement with their wrists and hands rather than their elbows. Doing this minimizes delt involvement and range of motion, which basically means you’re wasting your time performing side delt work.

    But more importantly, leading with your wrists places unnecessary stress on the rotator cuff. By leading with the elbow, you keep the focus on your delts and minimize the stress placed on your rotator cuffs.

  • Do NOT fully extend the arm

    This is a rookie mistake many newbie lifters make. Yet when you fully extend the arm and lock out the elbow, it places a tremendous amount of pressure on the elbow joints.

    Regardless of what exercise you're doing, it's never a good idea to lock out a joint.

    Create a slight bend in the elbow and then lock that position in place to perform your lateral raises. When you start opening and closing the elbow, you start to involve the triceps and reduce tension on the middle delt.

One final tip regarding side lateral raises, especially when performing them on the cable machine -- fight like hell to keep the weight from lowering on every rep. The side delt is an incredibly small muscle and it doesn’t encounter a great deal of time under tension when performing lateral raises the way most lifters do.


The way to get more out of the exercise is to hold the peak contraction for a solid second and then slowly “resist” the weight back down, fighting for every inch.
