Dumbbell Single-Arm Curl with Isometric Hold
One arm holds its dumbbell still with the elbow at a right angle while the other arm curls through full reps; then the arms trade jobs.
How to do it
Setup
Standing tall, a dumbbell in each hand, one arm bent to a right angle and held, the other hanging straight.
Steps
- Curl the straight arm through full reps.
- Keep the other forearm level and still.
- Switch the holding and the curling arm for the next set.
Common mistakes
Holding arm sinking as it tires: keep the forearm level; the hold is half the set. Leaning away from the moving bell: stand square. Shoulders creeping up: keep them down and relaxed.
Breathing
Steady through the hold, exhale on each curl.
