@armonadibi83's shoulder training advice, fact-checked

What did @armonadibi83 actually say?

Adibi laid out a shoulder training framework built around frequency, exercise selection, and sequencing. His core claims: train shoulders once a week, hit all three delt heads, lead with isolation work before pressing, and prioritize lateral raises over heavy presses for growth. He said "my shoulders and a lot of my clients' shoulders grew the most by doing side laterals," and argued rear delts are chronically neglected. He also cautioned against training shoulders the day after chest, recommending at least two days between sessions.

He proposed a volume structure of roughly six to seven sets for rear delts and six sets for side delts, with front raises added at the end. He favored cables throughout, citing feel and muscle connection over load. The sequencing advice, isolation first then compound pressing, is the most clinically interesting claim here and worth examining closely.

Does the science back this up?

Partially, yes. The evidence on shoulder training frequency, volume, and exercise order is more nuanced than Adibi presents, but he's not wildly off base either.

On frequency, training a muscle group twice per week generally produces modestly better hypertrophy than once per week at equal volume. Schoenfeld et al. (2016, Journal of Strength and Conditioning Research) found higher-frequency training produced greater muscle thickness when volume was equated. Once-a-week shoulders isn't wrong, but it's likely suboptimal for most people who aren't genetically gifted in that department.

On lateral raises driving growth: this tracks. The medial deltoid is poorly activated during standard pressing movements. Coratella et al. (2020, International Journal of Environmental Research and Public Health) confirmed that lateral raises produce significantly higher medial delt activation than overhead press variations, which tend to bias the anterior head. Adibi's intuition here is supported.

On sequencing isolation before compound work: this is a legitimate strategy called "pre-exhaustion," but the evidence is mixed. Simao et al. (2012, Journal of Strength and Conditioning Research) found that pre-exhaustion reduced overall load on subsequent compound exercises, which may limit total mechanical tension. It's not dangerous, but calling it superior for injury prevention is a stretch.

What did they get wrong (or right)?

He got the rear delt point right. Most gym-goers ignore posterior delts, and neglect shows up fast in posture and shoulder health. His cable rear delt pull is a reasonable exercise choice, and the "mind-muscle connection" cue, while sometimes overstated in fitness culture, does have some support: Calatayud et al. (2016, Journal of Human Kinetics) found that focused muscle activation cues increased EMG activity in targeted muscles.

Where he's off: telling people to train shoulders every other week because his grew fast is genuinely bad population-level advice. Genetics that produce rapid hypertrophy are not the baseline. Recommending reduced frequency based on personal outlier experience, without flagging it as such, is misleading to a 17,000-plus view audience.

His front delt advice is reasonable but incomplete. He correctly notes front delts are hit during chest pressing, and he's right that dedicated front raises can further develop them. However, for most trainees, front delts are already over-developed relative to rear and medial heads. His own caveat, "a lot of people overemphasize heavy heavy heavy presses," is valid, but he then adds front raises to an already front-delt-heavy routine without flagging this imbalance risk.

What should you actually know?

Shoulder training frequency should be based on your recovery capacity and volume, not on what worked for a single coach. The current consensus from meta-analyses, including Ralston et al. (2017, Sports Medicine), supports two sessions per week for most intermediate trainees as more effective than one when total volume is matched.

Volume in the twelve to twenty set per week range for delts is where most hypertrophy research lands. Adibi's proposed twelve to thirteen sets per session is on the higher end of a single session, and splitting that across two weekly sessions would likely serve most people better.

The cable-versus-dumbbell debate Adibi touches on is real. Cables maintain constant tension through the range of motion, which matters for lateral raises specifically. Dumbbell laterals have near-zero tension at the bottom and peak tension at ninety degrees. Cable or band variations keep load on the muscle throughout, which may improve stimulus quality. Adibi's preference for cables is defensible.

One thing worth flagging: this video sits in a TRT content category on this platform. Nothing in the transcript is specific to TRT patients, but shoulder joint health is a legitimate clinical concern for anyone on exogenous testosterone, particularly at higher doses associated with physique competition. Rotator cuff loading and tendon health deserve more attention than a quick "warm up first" comment provides.
