Isolation — shoulders

Lateral Raise

Dumbbells or cable

The lateral raise is the best exercise for building shoulder width. It isolates the middle delt and creates the broad, athletic upper body that pressing alone will not.

Shoulder width is one of the few things that visibly changes a physique from any angle, and it comes almost entirely from the middle deltoid — a muscle that pressing barely touches. The lateral raise is the only common exercise that trains it directly, which is why it appears in nearly every serious program despite using laughably light weight.

Technique

1. 1Lean forward slightly with a small bend in your elbows
2. 2Raise out to the side until your arms are parallel to the floor — no higher
3. 3Let the pinky side lead slightly at the top, as if pouring a jug
4. 4Do not use momentum — swinging reduces deltoid recruitment
5. 5Very light weights are normal here — 5–15 kg is a lot for most people

Common mistakes

• Swinging the weights up with the whole body

  Fix: If your knees dip to start the rep, halve the weight. This is a small muscle and 5–10 kg is genuinely challenging when done strictly.

• Raising above shoulder height

  Fix: Past horizontal the traps take over. Stop when the arms are parallel to the floor.

• Leading with the hands rather than the elbows

  Fix: Think about lifting the elbows out to the sides. Leading with the hands turns it into a front-delt exercise.

• Shrugging as you lift

  Fix: Keep the shoulders down and away from the ears. If they rise, the traps are doing the work you meant for the delts.

Sets and reps

How to progress

Weight increases here are painfully slow and that is normal — going from 8 kg to 10 kg can take months. Progress by reps first (12 to 20), then by adding a set, and only then by weight. Lateral raises tolerate high frequency well: three to four times a week in the 12–20 rep range beats one heavy session.

Variations

• Cable lateral raise

  Constant tension, including at the bottom where dumbbells give you a free ride.

• Lean-away lateral raise

  Holding a rack and leaning away increases the range and the stretch on the side you are working.

• Lu raise

  Raising all the way overhead with very light weight — high time under tension, and easy on the joints.
