How Iridium Programs This

Iridium treats the anterior deltoid as a distinct fatigue point, analyzing your recent flat and incline pressing volume to ensure you haven't exceeded your Maximum Recoverable Volume before programming this vertical push. Because dumbbell weight increments are often large, the algorithm uses RPE trends to verify you can handle higher rep ranges with control before prescribing a weight increase.

Form Cues

Plant your feet firmly on the floor to create a stable base
Keep your wrists stacked directly over your elbows throughout the lift
Press the weights up and slightly in, following a gentle arc
Brace your core and keep your ribcage down to protect your lower back
Lower the weights with control until your thumbs differ to ear level

Don't

Don't arch your lower back excessively to push the weight up
Don't flare your elbows out to 90 degrees; keep them tucked slightly (about 45 degrees)
Don't bounce the dumbbells at the bottom of the movement
Don't lock your elbows aggressively at the top

Common Mistakes

Excessive arching of the lower back
Flaring elbows too wide laterally
Cutting the range of motion short
Allowing wrists to collapse backward
Using momentum to start the press

Muscles Worked

This exercise primarily targets the anterior (front) deltoids, which are responsible for the initial drive of the weight overhead. It also heavily recruits the lateral deltoids for shoulder width and the triceps to complete the lockout at the top, while the upper traps provide essential stability to the shoulder girdle.
