Shoulder Training Manual

Round, capped delts are what make a physique look wide and powerful. But most lifters only press, only ever build the front head, and wonder why their shoulders still look narrow and flat.

If your shoulders are narrow, your front delts dominate, or your side and rear delts lag, this is the fix. The Shoulder Training Manual builds all three heads in balance, the way we train delts at Grinder Gym.

Build Round, Capped Shoulders. Width From the Side, Balance From the Rear.

Why Shoulders Stay Narrow

Most lifters press and call it shoulder training, which only builds the front head. The side delts that create width and the rear delts that balance the shoulder and keep it healthy get ignored. This manual trains all three and gives the side and rear the frequency they thrive on.

What Makes This Manual Different

Side Delts Lead

Lateral raises in real volume, including cable laterals from behind the body for the stretched position. The side delt is what builds width, so it gets the most work.

Rear Delts For Balance

Reverse pec deck, cable rear-delt work, and face pulls every session. They balance the shoulder, improve posture, and keep the joint healthy under all the pressing.

Front And Mass

Overhead pressing for the front head and total shoulder mass, already supported by your chest work so it does not need to dominate.

The Method

Mechanical tension, long-length loading on the laterals, lengthened partials, and constant-tension cable and machine work, programmed across three phases that accumulate, intensify, and overreach.
