Concentration Curl alternatives
If the Concentration Curl isn't happening today — the equipment is taken, you don't have it, or the movement doesn't feel right — here are 8 substitutes for the same job, each with what changes.
Which one when
- You need different equipment. For the same job — Barbell: Preacher Curl, Barbell Curl, EZ-Bar Curl; Machines and cables: Machine Bicep Curl.
- Same equipment, different angle or grip. If the movement feels off but the equipment is there — Standing Concentration Curl, One-Arm Dumbbell Preacher Curl, Dumbbell Curl, Hammer Curl.
- It hurts. If it's uncomfortable, try a substitute with a different grip or a machine and go lighter. Sharp pain, or pain that doesn't go away, is a reason to see a doctor, not to search for a substitute on a list.

- Same muscle: Biceps.
- Same entry bar: 1 of 3.

These are the same substitutes I show in the bot under "Alternatives", plus catalog exercises for the same muscle and movement. Difficulty is shown where I've broken the exercise down on its own page.
Swapping in the diary
In the bot, substitutes live on the exercise card: Exercises → the exercise → Alternatives. If one isn't in your list yet, I'll add it with one tap. A substitute keeps its own history and records — I don't mix them with the main exercise, so progress on each stays honest.
Log the substitute as its own exercise — I'll remember the weight and reps and give you a target next time.
