Lateral Raise Isometric Hold at 90 Degrees

Holding the top of a lateral raise puts the middle deltoid under long, unbroken tension at its shortest, hardest length. Even light dumbbells become brutal within seconds, making this a time-efficient way to build shoulder width and endurance. It works well as a burnout after your straight-set lateral raises or as a standalone delt finisher.

How to do it

  1. 1

    Stand tall holding a light dumbbell in each hand at your sides.

  2. 2

    Raise both arms out to the sides until they reach shoulder height.

  3. 3

    Keep a slight bend in the elbows and lead with the elbows, not the hands.

  4. 4

    Hold this position with the arms level, forming a straight line across.

  5. 5

    Keep the traps relaxed and the shoulders down away from the ears.

  6. 6

    Hold for time, then lower the dumbbells slowly to your sides.

Tips

  • Pour the pinkies slightly up as if emptying a jug to bias the side delt.
  • Go lighter than you think; the hold is far harder than reps.
  • Do not shrug the weights up; the height comes from the delts, not the traps.

Variations

Common mistakes

  • One arm quietly sinks below shoulder height while the other stays level, and you cannot feel the difference from the inside; hold side-on to a mirror or film one set to find out.
  • The elbows fold in as the delts burn, dragging the dumbbells toward your shoulders and shortening the lever that makes this hold hard in the first place.
  • Both arms creep forward toward the front of the body, which turns the hold into a front raise and hands the job from the middle delt to the front one.
  • The torso pulses forward and back in small rocks to flick the weights back up to height; once you need that to stay level, the set is finished.
  • Wrists break backward under the dumbbells so the hands hang below the forearms, and the forearms give out long before the shoulders do.

Frequently asked

How long should you hold a lateral raise isometric hold at 90 degrees when you are new to the exercise?
Start genuinely light, five to ten pounds in each hand, with three holds of 20 seconds and a minute between them. Progress in seconds before pounds: 20, then 30, then 40, and only then move up a pair of dumbbells. Used as a finisher it runs differently: raise the weights after your last set of lateral raises and hold until the arms drop, which is usually 10 to 20 seconds, once or twice.
What can I use instead of dumbbells for the lateral raise isometric hold at 90 degrees?
Two full water bottles, a can in each hand, or a small bag of rice all work, since the load needed here is tiny. A band stood on in the middle and held in both hands gives a similar hold, though its tension rises as the arms come up rather than staying even. Low cable handles are the smoothest version. With no load at all, holding empty arms out at shoulder height is still hard after 45 seconds and is a fair place to begin.
What is the lateral raise isometric hold at 90 degrees good for, and when should I skip it?
It keeps the middle delt under tension at its shortest length, which builds shoulder width and endurance, and it takes almost no time, so it works well as a finisher after pressing or raising work. It is not a strength builder, since nothing moves and the loads are small. Skip it if the shoulder pinches as the arms pass shoulder height, and hold below that line instead. It is also a poor choice as your only delt work, because the middle delt needs to move through range as well.
