Boulder Shoulders

For building visibly bigger, rounder deltoids across all three heads. It primes the delts with overhead reaches, explosive presses, overhead holds, and around-the-worlds, then grows the volume with reverse flies, T and Y pulls, and Y-pulls. The finish caps the boulders with lat pulls, rows, power pull-downs, anti-protraction, and diagonal pulls to fill out the shoulder.

Phase 1 · Prime the Delts

Prime the delts for growth. Overhead reaches, explosive presses, overhead holds, and around-the-worlds warm up and load the front and side delts through a full range. Priming the muscle first makes the growth work that follows more productive.

01

Overhead Reaches (Uncrossed)

2 sets of 12-15 repsHigh Anchor

Promotes overhead mobility and activation. Excellent for swimming and overhead mobility restoration.

How To
1Reach arms fully overhead against light resistance.
2Focus on full extension and overhead mobility restoration.
Coaching Cues
Full overhead reach
emphasize shoulder elevation
gentle stretch feel
promote mobility

Around The World

2 sets of 12-15 repsHigh Anchor

Targeted shoulder mobility and stabilization exercise. Focuses heavily on the lateral and posterior deltoids, rotator cuff, and scapular control along the lateral plane of the body. Excellent for building shoulder endurance, improving overhead range of motion, and correcting forward-rolling shoulder posture.

How To
1Stand facing away from the high anchor point with feet close together.
2Begin with arms straight, highly stretched out, and extended overhead in a wide V shape.
3Slowly sweep both hands downward and outward to the sides in a massive horizontal arc until they reach the sides of the hips.
4Actively raise the straight arms back up along the same wide, lateral path to return to the starting position.
Coaching Cues
Keep arms fully extended and locked out to the sides throughout the movement
maintain the wide lateral plane without letting the hands drift forward in front of the body
think about reaching outward toward the walls to maximize shoulder engagement
mindfully lift the arms back to the top position as the resistance bands slacken.

Phase 2 · Grow the Volume

Grow the volume. Reverse flies, T and Y pulls, and Y-pulls pile time under tension onto the rear and side delts for size. High-quality volume is what actually builds bigger deltoids.

01

Reverse Fly (Uncrossed)

3 sets of 12 repsHigh Anchor

Fundamental posterior chain exercise. Excellent for postural correction and activation across all programs.

How To
1Stand facing anchor point, arms extended forward at shoulder height.
2Pull arms apart horizontally, squeezing shoulder blades together.
Coaching Cues
Keep slight bend in elbows
lead with pinkies
pause at full retraction
avoid using momentum

02

T Shape Pulls

3 sets of 12 repsMid Anchor

Classic middle trapezius isolation exercise. Primary movement for addressing postural deficits and scapular retraction weakness. Essential for all programs focusing on posture correction and shoulder blade control. Often called reverse fly at 90 degrees.

How To
1Stand facing mid-level anchor, arms extended straight out to sides at shoulder height (90 degree abduction) forming letter T shape.
2Pull bands back horizontally, squeezing shoulder blades together while keeping arms parallel to ground.
3Maintain shoulder-height arm position throughout movement.
4Return with control.
Coaching Cues
Arms stay parallel to floor
lead with pinkies
elbows slightly bent
squeeze shoulder blades together forcefully
avoid dropping arms
maintain level shoulders
control return phase
think proud chest position.

03

Y Shape Pulls

3 sets of 12 repsMid Anchor

Lower trapezius dominant exercise crucial for scapular upward rotation and depression. Addresses scapular dyskinesis and prepares shoulders for overhead function. Essential for overhead athletes, swimmers, and anyone with shoulder impingement concerns.

How To
1Stand facing mid-level anchor, arms extended forward and up at approximately 45 degree angle forming letter Y shape overhead.
2Pull bands back and down, emphasizing scapular depression and retraction.
3Focus on engaging lower trapezius to pull shoulder blades down and together.
4Return with control.
Coaching Cues
Maintain Y angle throughout
initiate movement from shoulder blades
focus on downward pull of scapulae
reach tall at start of each rep
avoid excessive arm bend
control descent
think pull shoulder blades into back pockets.

04

Y-Pulls (Uncrossed)

3 sets of 12 repsLow Anchor

Activates lower trap and serratus anterior. Critical for scapular upward rotation and overhead function.

How To
1Stand facing low anchor, arms at sides.
2Pull bands up and out forming a Y shape overhead.
3Focus on lifting through shoulder blades.
Coaching Cues
Initiate movement from shoulder blades
keep arms straight
reach tall at top position
control the descent

Phase 3 · Cap the Boulders

Cap the boulders. Lat pulls, rows, power pull-downs, anti-protraction, and diagonal pulls finish the delts and surrounding muscle for a full, rounded look. You finish with visibly bigger shoulders.

01

Lat Pulls (Crossed)(partial hip hinge)

3-4 sets of 10-12 repsHigh Anchor

Activates lats for swimming and overhead athletics. Excellent for thoracic extension and lat engagement.

How To
1Stand facing high anchor, pull from high to low position activating lat muscles and promoting thoracic extension.
Coaching Cues
Emphasize lat engagement
pull elbows to ribs
promote thoracic extension
control movement

Set your resistance

Light, medium, or heavy?

We call for an effort level instead of a specific weight, because the right resistance depends on you, the movement, and where you are in your training. For the sets and reps listed on each exercise, pick the resistance that makes the last few reps feel like the level shown.

Light

You finish the set with several clean reps still in the tank. The work stays easy and fully controlled from the first rep to the last.

Medium

You could manage a few more reps at the end, but not many. The final reps take real effort while your form holds.

Heavy

You reach the last prescribed rep with little or nothing left. Completing every rep with good form is genuinely hard.

These are starting points, not rules. Everyone is built differently, so adjust to fit you: size down if your form breaks before the final rep or a movement aggravates a symptom, and only size up once every rep feels smooth and pain free. When you are unsure, choose the lighter option.
