Biceps
A biceps curl performed lying back on an incline bench, which stretches the biceps at the bottom for a deeper range of motion than a standing curl.
How to do it
- Sit back on an incline bench set to about 45-60 degrees, a dumbbell in each hand hanging straight down.
- Keep your upper arms still and pinned against the bench pad.
- Curl the dumbbells up toward your shoulders.
- Squeeze your biceps at the top, then lower back down slowly to a full stretch.
- Avoid letting your shoulders roll forward off the bench.
Coaching tips
- The incline position prevents cheating with momentum, making this a strict, isolation-focused curl.
- Control the lowering phase — the stretch at the bottom is where this exercise does most of its work.
- Use lighter weight than a standing curl since the position removes any assistance from body swing.
Common mistakes
- Letting the elbows drift forward away from the bench.
- Rushing through the stretched bottom position instead of controlling it.
Frequently asked questions
What bench angle is best for incline curls?
Around 45-60 degrees works well — steep enough to stretch the biceps, but not so flat that it turns into a standing curl.
