Spider Curls Dumbbell:Complete Guide to Stronger Biceps
Look at the curl rack in any commercial gym on a Monday night. Somebody takes the 40s and leans back like he is pulling a lawn mower starter cord and heaves the bells up. His elbows are jutting out. His back bends at the bottom. His biceps? Hardly.
I’m not mocking him. Most of us curled that way for years. The weight looked impressive, so we kept chasing it, and our arms stayed about the same size.
Spider curls fix this by taking your body out of the equation. You lie chest down on an incline bench with your arms hanging toward the floor. Nothing swings because there’s nothing left to swing. The spider curls dumbbell version is also the easiest to set up, at home or in a crowded gym.
Below you’ll find exact form, the muscles involved, sets and reps, the mistakes that show up most often, and a short arm workout. I’ll also point out where the hype runs ahead of the science.
What Are Spider Curls Dumbbell?
A dumbbell spider curl is a biceps curl done lying chest down on an incline bench. Your arms hang straight down, and the bench holds your torso still. That leaves the biceps to lift the weight with very little help from anything else.
Understanding the Spider Curl Exercise
The name comes from the manner your palms hold over the pinnacle of the bench, a piece like spider legs. It appears easy. It isn’t. The first time you attempt it along with your normal curl weight, the dumbbells feel oddly heavy, and your reps get short and unsightly. That’s the exercise doing its task.
Why Spider Curls Are Different From Regular Curls
A standing curl gets your hips, lower back, and shoulders involved. Spider wraps up that door. Your upper arms are also in front of you, not down by your sides. Many coaches think this puts additional stress on the short head of the biceps. That’s a fair hypothesis, I’d suggest, not a proven truth, as the evidence is sparse.

Equipment Needed for Spider Curls Dumbbell
You will want an adjustable bench and 2 dumbbells. Position the bench at around 45 degrees. Benches like the Rep Fitness AB-3000 or the Rogue Adjustable Bench 2.0 continue to be sturdy under pressure, which is essential whilst you are lying face down on one.
Bowflex SelectTech 552s and PowerBlocks reduce the need to move weights around, even though shifting weights between gadgets wastes time. For this exercise, I chose my very own constant pair of rubber hex dumbbells. You can get the next weight in seconds.

Muscles Worked During Spider Curls Dumbbell
Spider curls mostly train the biceps brachii. The brachialis, the brachioradialis, and your forearm flexors help out, while your upper back and rear delts keep you steady on the bench.
Primary Muscle: Biceps Brachii
Your biceps has two heads, one long and one short. Both pass the elbow, so both help bend it, and each flips your palm upward. Every curl uses both heads. What makes spider curls alternate is how difficult it is to steal reps. New to anatomy? Our biceps anatomy explained post covers the fundamentals.
Secondary Muscles Involved
The brachialis lies under the biceps. It’s a robust elbow flexor, and building it can make your upper arm look thicker from the side. The brachioradialis runs alongside the pinnacle of your forearm. Your finger and wrist flexors grip the handles. Meanwhile, your rear delts, traps, and rhomboids work quietly to hold your shoulders from rolling ahead.
Why Spider Curls Improve Biceps Activation
Let’s be honest here. EMG investigations of curl variations found largely modest variances. So no, spider curls aren’t going to get your biceps to fire twice as fast. They show you stuff. Without momentum, you can feel the exact instant when the muscle is performing and when it is not. For many lifters, it alone promotes a greater mind-muscle link. Check out our best adjustable dumbbells to assist you in building on this.
How to Perform Spider Curls Dumbbell Correctly
Set an incline bench at about a 45-degree angle and lie face down with your head over the top edge. Let your arms relax with your fingers down. Spider Curls Dumbbells without transferring your hands higher; pause briefly at the top, after which drop for around three seconds.
Step-by-Step Spider Curl Technique
- Adjust the bench to roughly 45 degrees.
- Pick up a light pair of Spider Curls Dumbbell and lie chest down on the pad.
- Let both arms hang straight toward the floor, palms forward.
- Bend only at the elbows and curl the weights up.
- Squeeze your biceps hard for a second at the top.
- Lower slowly over about three seconds, stopping just before your arms lock out.
Proper Starting Position
Set your feet on the floor behind the bench, on your toes or the balls of your feet. Press your chest into the pad and keep your head just above the top so your neck stays neutral. Let your shoulders drop away from your ears. Nothing should feel pinched.
Spider Curls Dumbbell Movement and Range of Motion
Keep your elbows down to the floor throughout the rep. Don’t get all the way down into a dead hang at the bottom so the strain stays on the muscle. Curl at the top until your forearms are almost touching your biceps. Half rep, large weight will always lose to full range, lighter weight slower.
Breathing Technique During Spider Curls
Breathe out, curl up. Going down. Breathe in. Sounds basic, but quite a few folks preserve their breath on hard sets and end up lightheaded. Keep the air circulating.
Benefits of Spider Curls Dumbbell
The biggest advantage of spider curls is strictness. They keep you honest, keep the biceps tense, and make every rep count. With time, that leads to bigger, stronger arms and crisper definition.
Builds Stronger and Bigger Biceps
You train it hard enough with adequate weekly volume, and muscle increases. Spider curls place that focus completely on the biceps. Gradually add a rep or a little weight, as we talk about in our progressive overload instruction
Improves Muscle Isolation
Your back and shoulders can’t rescue a tired biceps on this exercise. That can feel annoying. It’s also useful because it shows you the real limit of the muscle you’re trying to grow.
Reduces Momentum During Curls
The bench immobilizes your torso so there is hardly any swinging. Cleaner sets also mean less strain on your lower back, which is a good benefit if you ever finish a curl exercise with a sore spine.
Helps Improve Arm Definition
Bigger biceps give you shape on the front of the arm. There is no activity that burns fat from one location. Combine your training with smart eating to see the definition. Spider curls create the muscle; your diet decides how noticeable it is.
Common Spider Curls Dumbbell Mistakes to Avoid
The four biggest faults are utilizing too much weight, letting your elbows slide, using momentum to swing, and not completing reps. Fix those and the workout begins to work as it should.
Using Too Much Weight
This one wins by a country mile. Let’s say a lifter curls 40s standing, and takes the same set for spider curls. The reps become short, jerky pulls, and his biceps feel nothing. Usually, it fixes it by dropping to 25s and slowing down. As a rough guide, your severe spider curl weight should be 20 to 30 percent lighter than your standing curl weight.
Moving Your Elbows Incorrectly
If your elbows start to move back, then you’re doing sloppy rows. If they wander ahead, you cut the distance. Hold them straight down to the floor. And hold.
Using Momentum Instead of Muscle Control
Some people lift their chest off the pad to launch the weight. That defeats the entire point. Keep your torso glued down and take about three seconds on the way down.
Performing Partial Repetitions
Stopping halfway up or down robs the biceps of range. Use a lighter Spider Curls Dumbbell and finish every rep. If your elbows start to ache, our elbow pain prevention for lifters guide can help.
Spider Curls Dumbbell vs Other Biceps Exercises
Spider curls are not about heavy loading but tension. You can go heavier with regular curls. Preacher curls take the bottom of the range. Concentration curls are one arm at a time. An excellent program combines these.
Spider Curls vs Regular Dumbbell Curls
When you do standing Spider Curls Dumbbell , your body aids you so that you can lift more weight. It’s beneficial for overall volume. Spider curls aid you, making them better for developing control.
Spider Curls vs Preacher Curls
In the preacher curl, your arms rest on an inclined pad, and the lowest point of the rep gives an awesome stretch for the biceps. Some lifters feel that strain in the tendon on the elbow joint. Spider curls permit your palms to dangle free, which many humans find gentler on the joint.
Spider Curls vs Concentration Curls
Concentration curls involve holding one elbow to the inside of your thigh. They are wonderful for concentration and finishing an exercise. Spider curls work both arms at the same time and also help give you a steadier base.
How Many Sets and Reps Should You Do?
Most lifters do well with 3 to 4 sets of 8 to 12 reps. Beginners can begin with 2 to 3 sets of 10 to 12, and lifters chasing strength can use heavier sets of 6 to 8.
| Goal | Sets | Reps |
|---|---|---|
| Beginners | 2 to 3 | 10 to 12 |
| Muscle Growth | 3 to 4 | 8 to 12 |
| Strength Focus | 3 to 5 | 6 to 8 |
Beginners
Keep the weight light and stay at two or three sets while you learn the setup. Your only job is clean reps.
Intermediate Lifters
Move up to three or four sets. Add a rep each week, then a little weight once you reach the top of your rep range.
Muscle Growth Training
Research reviews, including work from Brad Schoenfeld and colleagues, suggest muscle can grow across a wide range of rep counts. The key is taking sets close to failure. Ten or more hard weekly sets per muscle is a sensible starting point for many people.
Spider Curls Dumbbell Variations
You can exchange the bench mind-setangle, the grip, or how many hands are on the bar at once. The setup remains strict, but every tweak shifts the texture of the exercise a bit.
Incline Spider Curl
Change the bench angle anywhere from 30 to 60 degrees. Small tweaks change how your shoulders sit and how the curl feels, so test a few and keep what works best for you.
Alternating Spider Curls Dumbbell
Curl one arm while the other hangs. This gives each arm a brief rest and helps you focus on one side at a time.
Single Arm Spider Curl
Train one arm per set. It’s a simple way to spot and fix strength gaps between your left and right sides.
Hammer Spider Curl Variation
Turn your palms to face each other. This neutral grip shifts more work to the brachialis and brachioradialis.
How to Add Spider Curls Into Your Arm Workout
Do spider curls first, while you’re fresh. This 25-minute routine works well twice a week:
- Spider Curls Dumbbell: 3 sets of 10, rest 90 seconds
- Hammer curls: 3 sets of 10
- Concentration curls: 2 sets of 12 per arm
- Triceps extensions: 3 sets of 12
