Barbell spider curls (also called spider curl barbell) place you face-down on an incline bench with arms hanging straight down holding a barbell. This position eliminates momentum and creates maximum tension at peak contraction. The barbell allows heavier loading than dumbbell spider curls.
When to use it
Use for short head emphasis with heavier loading.
Who it's for
Intermediate lifters wanting peak contraction focus.
Lie face down with your chest near the top of a 45-degree incline bench. Let your arms hang straight down perpendicular to the floor. Keep upper arms completely stationary—only your forearms should move as you curl toward your face.
Also targets: Brachialis, Forearms

We slot it into the right day with sets, reps, and progression you can follow.
Lie face down on incline bench at 45 degrees.
Let arms hang straight down holding barbell.
Keep upper arms perpendicular to floor.
Curl barbell up toward face.
Squeeze hard at peak contraction.
Lower under control.
Barbell allows heavier loads than dumbbells.
Focus on peak contraction.
Keep arms vertical throughout.
Use barbell spider curls when you want heavier loading in the spider curl position. They work well after primary bilateral curls as a secondary movement for short head emphasis and peak contraction.
Letting elbows drift.
Letting your elbows drift wide during the Spider Curl Barbell shifts load onto your shoulder joint instead of your Biceps brachii. Keep them tucked at about 45 degrees to protect your rotator cuff and keep tension where it belongs.
Using too much weight.
Loading more weight than you can control on the Spider Curl Barbell forces compensatory movement patterns that bypass your Biceps brachii. Drop the weight until you can perform every rep with clean form — your results will actually improve.
Swinging the bar for optimal results.
Bouncing or using momentum during the Spider Curl Barbell takes work away from your Biceps brachii and puts your connective tissue at risk. Control the weight through the full range — if you can't, lower the load.
Intermediate lifters wanting peak contraction focus.
Lower reps with heavier weight builds raw strength. Your muscles and nervous system adapt to handle more load over time. This range is best for strength-focused goals.
This rep range keeps your muscles under tension long enough to trigger growth. Most people see the best muscle-building results in this zone. It balances strength and muscle size.
Higher reps with lighter weight builds muscular endurance and improves conditioning. This range is good for joint health and building work capacity.
General guideline: 3 sets of 10-12 reps. Rest 60 seconds.
