WHAT WE'RE DOING TODAY
Other names for this exercise: Banded Scott Curl
ALL WE'RE DOING:
Doing a bicep curl while kneeling over a fitness ball.
Preacher Curls are just a different way to work our biceps. Doing a bicep curl will ALWAYS involve bending and unbending your elbows, that's almost the only thing biceps do so no getting around that, BUT we can still introduce some challenges to the muscle by changing our body & arm position while we're doing it.
In this exercise also known as the Scott curl, rather than having our upper arms by our side as in standing, we will have them raised higher & in front of us on top of a yoga ball. Doing this will mean that more of the muscle UNDERNEATH the biceps, the brachialis, will be working harder than usual AND, the short head of that 2-headed biceps muscle will also be doing more than usual. That is because this position puts the long head of the biceps in a position where it is not as capable of helping to bend the elbow.
Since the stability ball is helping stabilize the upper body and upper arms, this will decrease the need to worry about stabilizing the upper arm and shoulders with your own muscles & mental energy, so the focus can be on contracting the elbow flexors and supinators.
The band is nice because you can work the end range of flexion more - with dumbbells it’s hardest when the dumbbells are parallel which would be lower, and with a band, the muscle will be working hardest at the top position - just a different way to work the muscle. Always good to vary how we work our muscles for best results.
PROPER FORM: Band Kneeling Preacher Curl
EQUIPMENT, SETS & REPS
Main set (3: Light/Med/Heavy):
X-Heavy Band (I recommend getting this too if you plan to use resistance bands frequently).
SUGGESTED STARTING WEIGHT FOR WOMEN:
Moderate resistance bands
SETS & REPS:
2 sets of 8 reps
Quicker up movement (concentric) – increased power will increase the involvement of the brachioradialis. And slow lowering (eccentric).
BODY POSITION FOR THE Band Kneeling Preacher Curl
BALL- NOTE: I find that the ball material and my bare elbows can sometimes cause a pull that is not comfortable- something that fixes that for me is to put a towel over the ball, or wear long sleeves.
BAND: Anchor the band low (lower than hip level - dependent on ball size; you want the band to be pulling your hands down).
KNEELING: Kneel on the floor and lean over the ball.
BODY STANCE: Leaning on the ball so that your upper body and arms are stabilized on the ball. The exact positioning will be dependent on your height, size of the ball; the goal is to have your upper arms resting and stabilized with your upper arm in front of your body rotated so that the eye of your elbow (soft inner part ) is facing up - and the pointy part of your elbow is down on the ball. Your elbows will be around in line with your shoulder joint. The position should be comfortable and stable. Neutral spine position, sternum lifted shoulder blades in and down the back.
ARMS: Shoulders - upper arm forward (flexed) and rotated so the soft side is forward (externally rotated), supported on the ball. Your elbows are slightly bent in the starting position. It is important not to let the band pull your elbows into a hyperextended position (it will strain the ligaments).
HAND/GRIP: Neutral grip - Palms facing inwards – towards each other. Hold one end of the band in each hand. The band enters your hand on the side of the little finger, crossing your palm to the thumb side.
NECK: Neutral and relaxed.
NOTE: It’s easy in this position for the band to kind of pull your whole body forward, and then that won’t work the biceps well- try to find a position, like digging your toes into the ground and sitting back on your haunches a bit more to counteract that pull so that your body can stay in place during the movement.
HOW TO DO
HOW TO DO Band Kneeling Preacher Curls
CUE: Concentrate on squeezing the inside portion of your biceps.
Bend your elbows (flexion) to pull your hands up towards your shoulders.
As you pull your hands up, rotate your forearm so that your palm faces up. The pinky side of your hand should be leading the way, and should come close to the inside of your shoulder (where it meets the torso).
Try to complete the forearm rotation by the time your elbows are about half way through the movement (to maximize the resistance on the biceps and supinator muscles).
Once you have reached the end of your elbow flexion (fully bent), squeeze the inside of your biceps and pause.
Slowly straighten the elbows and begin the next rep.
HOW TO SAFELY GET OUT OF THE EXERCISE
From the starting position, release the band.
WHAT TO AVOID WITH THE Band Kneeling Preacher Curl
Guess what? Good news! Many avoids are the same for most movements. Once you learn the basics, there's really only a few extra avoids for each individual movement.
1. Avoid Elbows Flaring
AVOID: Letting your elbows move out to the sides
- This will change the downward pull of gravity and will increase the activity of the shoulder.
WHAT TO DO:
- The upper arm should be resting on your sides, not moving.
2. Avoid Hyperextending Elbow Joints
AVOID: Hyperextending (bending backwards) the elbow joint. In the starting position, the weight can pull your hand down and cause your elbow to hyperextend.
- This can strain the ligaments of the elbow joint.
WHAT TO DO:
- Keep a slight bend in your elbow if needed.
- Lower the resistance by using lighter weights or band.
3. Avoid Rounding Shoulders
AVOID: Rounding the shoulders forward.
- This means that you are trying to use the anterior deltoid and chest muscles to help bend the elbow.
- This can decrease the space between the shoulder blade and the upper arm bone (humerus) and irritate the tissues.
WHAT TO DO:
- Pull the shoulder blades in and down the back, and lift the sternum to correct your posture.
4. Avoid Shifting Weight
AVOID: Leaning back or shifting your weight.
- This will decrease the work being done by the muscles of the arms and upper back
- This is a common way the brain will try to make the exercise easier - using your body weight to help pull the hands up.
WHAT TO DO:
- Keep the shoulders over the hips, over the feet, keep your weight evenly distributed in your feet.
- Bend the knees slightly and activate your core muscles.
5. Avoid Hunching Shoulders
AVOID: Hunching the shoulders up towards the ears.
- This can happen when you try to use your upper trap to help the biceps
- You will note decreased space between the shoulders and earlobes.
WHAT TO DO:
- Pull the shoulders down to keep the space between the ear and the shoulder during the entire rep - this opens up the shoulder to avoid tendon irritation and decreases the activity of the upper traps.
6. Avoid Bending Wrists
AVOID: Bending at your wrists.
- Poor alignment (bent forward or backward) or repetitive movement through the wrist can lead to joint and/or soft tissue irritation or injury over time.
WHAT TO DO:
- Your wrists should be in line with your forearm and should be still throughout the exercise.
7. Avoid Bending Neck
AVOID: Bending neck.
- This can lead to neck strain, injury or damage over time.
- You may feel neck discomfort, or gripping with your neck muscles.
WHAT TO DO:
- Gripping neck muscles in an attempt to stabilize the shoulders: relax the neck and activate the core muscles more, activate the scapular stabilizers in retraction and depression.
WHAT & WHY
BENEFITS OF TRAINING THE biceps
How many ways can you adjust the basic bicep curl to make it do something slightly different? A few, a few. This is one of the most weird ones probably. The positioning of this bicep curl is such that it lets us target the the short head of the biceps a bit more- which is that more ball shaped portion of the muscle (which we can only see if we like, workout a lot for awhile) that's towards the inside of our upper arm close to our chest muscles.
Other than that, the movement is the same as far as just bending our elbows and rotating our palms to face up at the top of each rep.
WHY DO WE EVEN CARE?
VARIETY FOR BICEPS
The biceps brachii (bicep means that the muscle has two heads, and brachii - meaning arm). Since the biceps is technically made up of two portions of muscle, changing up positioning and how we lift weight can target one portion more than the other and vice versa.
Both heads work to bend (flex) the elbow and rotate our forearm so the palm of our hand is up or forward (supination). To improve the strength and health of the biceps muscle it is a good idea to include exercises that will work both parts of the muscle. It is also always a good idea to add variety to your workout so that the muscles are worked in many different positions. Movements that put the arm in positions that move the short head to face forward will preferentially work the short head more than the long head.
Plus, who doesn't like to be in a slightly more "resting" type position, which we get to do with the stability ball supporting our torso & being on our knees.

How to Feel What Muscle is Working
Bend your elbow. Place the other hand on the upper arm with the bent elbow. Lift a heavy object with the arm - you will feel the biceps contract under your hand.
SPIFFILICIOUS FACTS ABOUT MUSCLES & MOVES
This exercise targets the brachialis and the short head of the biceps brachii muscle. The short head attaches to the coracoid process at the front of the shoulder blade, and lies along the inside of the upper arm. The long head of the biceps crosses the shoulder joint to attach to the “socket” portion of the shoulder joint (on the shoulder blade). Positioning the upper arm in flexion puts the long head of the biceps in a position where it is not able to contribute as much to elbow flexion. The EMG studies support this and the thought is that the long head is shortened over the shoulder, so that it is not able to produce as much force. Going back to the force-length curve - the muscle is strongest in the middle of the range - not shortened or lengthened.
Starting in this position also works the elbow flexors the hardest when they are in a stretched position. The force on the biceps is greatest when the forearm is parallel to the floor. Working the muscles in this lengthened position is thought to promote muscle growth.
Rotating the upper arm out arm is thought to bias the short head of the biceps by changing the orientation of the muscle fibers, meaning the line of pull on our muscles is more opposite the short head which means it will be in a place to do more of the work more naturally. Positioning the arm so the fibers that you want to get are directly opposite the pull of gravity.
To get more detailed - it has to do with the origin and insertion of the muscle and the lever arm of the muscle bundle itself - this is called the mechanical advantage of the muscle. So the thought is that a narrow grip biceps curl will rotate the arm so that the long head is facing forward and a wide grip will position the short head forward. A stability ball is used to stabilize the upper body and upper arms. This will decrease the need to worry about stabilizing the upper arm and shoulders, the focus can be on contracting the elbow flexors and supinators.
The long head of the biceps originates towards the top of the shoulder joint, right above where the upper arm bone forms a joint with the shoulder blade. The long head is positioned towards the outer side of the upper arm. The short head attaches to the shoulder blade towards the inside of the shoulder - right below the end of the collar bone. If you find the end of the collar bone closest to the shoulder joint, and drop your fingers down about ¼ inch you can feel the place where the short head of the biceps attaches. The short head of the biceps lies towards the inner side of the upper arm. Both of the two heads travel down the soft (hairless) part of the arm and join about mid-way down, then cross the elbow joint and insert on the forearm.
ALLLL MUSCLES & WHEN
ALL MUSCLES WORKING & WHEN DURING THE Band Kneeling Preacher Curl
The shoulder blade is held down and back (depression and retraction - rhomboids, lats, pectoralis, serratus, trapezius), and to hold the upper arm still. The upper arm is positioned and supported in flexion and external rotation. This puts the long head of the biceps in a position where it is shortened and at a disadvantage - it is not as capable of helping to bend the elbow in this position.
The brachialis and biceps (with the short head in a position to work more than the long head) contract concentrically to bend (flex) the elbow and rotate (supinate) the forearm. The brachioradialis does not contribute unless power or speed is needed – for quicker movements or heavy loads. The supinator muscle will assist with supination. The greatest resistance on the elbow flexors will when the weight is parallel to the floor. As the elbows bend the load on the muscles will decrease.
The wrist muscles (flexor carpi radialis FCR, flexor carpi ulnaris FCU and palmaris longus)) work to hold the wrist in a neutral position as the band pulls down on the hand.
The biceps brachii and brachialis work eccentrically to straighten the elbow and return to the starting position.
