Since the discs and other spine structures become more vulnerable with injury and age, trainees returning from a back injury, older trainees in general, and the simply risk-adverse may find these techniques useful in avoiding further unnecessary wear and tear.

Motivation for Muscular Arms

Acquiring muscular arms is a classic motivation for fitness enthusiasts, and the curl is the obvious go-to option. The standing biceps curl has a special place for those of us who got started at home with a vinyl-covered barbell set. We may not have had a squat rack or bench, but we could put the plates on the bar and start curling right out of the box.

“I’ve found that being aware of the biomechanics behind curls (and other exercises) and adapting accordingly can really help manage that.”

The standing curl is a perfectly adequate exercise, especially at the beginning levels of strength and effort. But as we get more experienced, push harder, and become stronger, we use more weight and the curl can put an unexpected strain on the back.

“Unexpected” from the biceps curl, that is, but very expected from those who study the back:

The likelihood of problems increases if the spine is overloaded (lifting weights) when it is out of the neutral position. The spine is designed to bear loads and stresses in neutral; if it is not aligned properly those loads and stresses are transmitted unevenly and transferred to structures that were not designed for load-bearing.⁵

If improper posture or lifting is repeated continuously, this will fatigue or weaken the spinal structure increasing the chance of injury. The same continual exposure to force on the spine will cause general wear and tear on the spinal column as we age. This decreases the space between the vertebral bodies and allow forces on the spine to affect the nerves and spinal column, ultimately resulting in increased pain and decreased function.¹⁰

Avoid Unnecessary Pain

Conventional instruction for the basic standing curl doesn’t contradict any of this, especially with lighter weights and intentionally strict form. But as you train with heavier weights or move deeper into fatigue, there is an inevitable lean away from the weight, especially as you approach the sticking point (forearms horizontal). This results in a sway back posture, a deviation from the neutral spine, which is discouraged as a postural condition, much less with an additional load and effort through the spine.

This isn’t necessarily “cheating,” though. With your feet parallel, in line with your shoulders and hips, your base of support is a straight line in the frontal plane. As you curl the weight forward, the weight moves your center of gravity forward of that base of support, the very definition of unstable. What keeps us from face planting is the shoulders and head being drawn opposite the weight by the contraction of the deep back muscles, creating the sway back, but bringing stability to the body-barbell system. Notice, as you complete the curl, the sway back goes back to neutral. You don’t continue to bend backward when the weight is up by your shoulders.

Curling with your back against a wall doesn’t correct this, because the midway point of the curl still changes your center of gravity. Instead of your head and shoulders moving back, your hips will move forward as your body tries to regain stability.

A more effective fix is a staggered stance. By placing one foot in front of the other, you are rotating your base of support ninety degrees – front-back instead of side-to-side. The shift in center of gravity stays within your base, the body-barbell doesn’t need to regain stability, and so you maintain the neutral posture. Within the staggered stance, it also helps if you alternate curls rather than do both arms simultaneously. In effect, you reduce the total weight impacting the center of gravity.

Scott Bench Curls

The Scott bench curl , and its machine versions, stabilizes the body-barbell differently. This curl creates a cantilever – a beam that projects beyond a fulcrum, supported by a larger weight on the other side of the fulcrum. Out of gym, this design is used to provide stability without a second support, like a shelf or balcony. On the Scott bench or machine, your arm is the beam and the bench is the fulcrum. Since your bodyweight is more than the weight in your hands, curling the weight doesn’t shift the center of gravity enough to cause the sway back.

The Age Factor

You may still find some mid-to-upper back discomfort with the Scott curl and the standing curl, or for that matter any exercise with the weight held in front, even with a neutral spine. That’s because your internal center of gravity, without an external load, is always in front of your spine when your torso is vertical. What keeps your spine from falling into flexion is enough of a contraction of the deep spine muscles to hold the posture. The longer you’re upright, the longer they work.

“Obviously, if you are in sharp, stabbing, I-can’t-breathe pain, your biceps are the least of your worries.“

Add to that, any additional bodyweight you carry in front: a big chest, forward head, rounded shoulders, a big belly, plus whatever you carry in your hands. Then, you work out with the weight or kettlebell held in front of your body. Like any other muscle, the deep back muscles can get fatigued. For those of us with more years, older discs don’t absorb forces as well as younger discs, leading to a range of issues. All of which is made worse with a prior injury. So the combination of fatigued deep back muscles, older discs, and life experience may make any kind of standing or seated curl uncomfortable.

If your curl of choice or necessity is the Scott bench or machine and you want to minimize the strain on your back, do your best to keep your shoulders and head upright, to not add to the forces pulling your spine into flexion. Keep your shoulder blades down and back and your head up, even if it means using a little less weight. You may feel the biceps more directly because the body won’t be shifting part of the load to other structures for the sake of moving the weight.

Incline Curls

The back-friendliest biceps exercise may be the incline curl, either with dumbbells or machine. The bench expands your base, so the movement of the weight doesn’t affect stability. Leaning back, your internal center of gravity is no longer trying to pull your spine into flexion for your deep back muscles to have to counter. It’s also established that the reclined position with bodyweight alone puts less strain on the discs than either sitting or standing. The reclined position with lumbar support is better yet.

As far as the exact angle to set the incline, there is a reduction in disc pressure from ninety degrees, to ninety degrees with lumbar support, to 110 degrees, to 110 degrees with lumbar support, and so on, down to lying flat. So how far you get past 110 degrees is probably an individual preference. I’d suggest low enough that you don’t notice the dumbbells pulling you forward at the midpoint of the curl, but not so low that the front of your shoulders strain.

Assess Your Own Needs

Obviously, if you are in sharp, stabbing, I-can’t-breathe pain, your biceps are the least of your worries. And making these changes is no guarantee you won’t end up that way, because so many other things in and out of the gym contribute to our health and fitness.

But somewhere between wretched pain and invulnerable is a level of discomfort that’s just distracting, that may hint at problems to come, and I’ve found that being aware of the biomechanics behind curls (and other exercises) and adapting accordingly can really help manage that.

What I learned from my own ruptured biceps may help you avoid injury. I’ll explain what happened, what I did about it, and leave you with an idea of how to make your own training easier on your joints.

Me – back in my bodybuilding days

A Little Background

Weight training started for me in the mid-1970s as part of high school wrestling. I slowly got drawn into the magazines, the gyms, and the new-at-the-time Nautilus machines. I was more of a recreational athlete than a competitive one. I did a couple of bodybuilding competitions and a couple of triathlons, but those only punctuated my exercise through the years.

In 1983, I was hired as a personal trainer at the Sports Training Institute in New York City. Certifications came later, first a CSCS and then CPT. I stayed in personal training in various formats, supervised trainers, and taught the personal training curriculum at some community colleges. This is all to say I had the paper and experience to think I knew what I was doing.

Just prior to my fortieth birthday, I was in my basement gym and had just started a set of slow curls when I felt a twinge at the back of my right shoulder. I put the weight down, pulled my sleeve up, and found a black-and-blue golf ball where my right biceps had been. I had a proximal biceps rupture.

What Was I Doing Wrong?

At the time, John Elway had recently experienced the same, so even with dial-up Internet information on the injury was easy to find. The first suggestion I found was “manage the pain.” Not an issue with me, since I wasn’t throwing a football eighty yards when it happened.

The next recommendation was to not repair the injury. The thinking being the repair wouldn’t hold, and other muscles around the biceps would compensate anyway. The biceps has two attachments on the scapula, so one is expendable functionally. Aesthetically, not repairing the injury does make a difference. There’s a nice divot where the “peak” of my muscle had been, although that is less noticeable over time.

But in my research, the thing that got my attention was that the injury is common among sixty-year-old men – not 39-year-olds. What could I possibly have done to prematurely age my shoulders?

The Usual Suspects

At the time of the rupture, I was not lifting an especially heavy weight. I was not deadlifting, power cleaning, or bouncing off the bottom of chin ups, nor was I in the habit of doing those things.

“I concluded the accumulated wear and tear on the shoulders from years of working out must have frayed the tendon until it popped. It just reached the critical point during that curl.”

I did a simple standing curl in a slow cadence. I was not on antibiotics, and I do not and did not use anabolic steroids, HGH, or any other ergogenic. I didn’t pitch baseball or do any other sport excessively. Any of the obvious, direct causes of an acute rupture didn’t seem to apply.

I concluded the accumulated wear and tear on the shoulders from years of working out must have frayed the tendon until it popped. It just reached the critical point during that curl. It could just have easily have happened while shooting baskets, doing yard work, or playing with my kids. I decided to review my first 25 years of exercise to see if there were things in my workouts that could be improved.

The Culprit: Excessive Range of Motion

At some point or another, I had dabbled with just about every kind of exercise. If they hurt in the wrong way, i.e. joint discomfort, as opposed to muscle burning, I generally got away from them before I became injured or used them judiciously. Press behind the neck, upright rows, side raises with the pinky up, Olympic lifts, and powerlifting all fell into this category. So while wear and tear may have accumulated, I didn’t do any suspect exercises consistently enough to blame one of them in particular.

But the one mistake I consistently made was an excessive range of motion with chest work. No matter which chest exercise I did, I allowed the weight to push my upper arms as far back behind me as possible. Due to the notions and cues of “full range of motion” and “touch the bar to your chest,” I thought there was some magic benefit to loading that overstretched position. I later found out it’s a good strategy for creating anterior instability, which turns out to be a bad idea if you like healthy shoulders.

“A vulnerable joint position is just that, whether you see it in sports, manual labor, martial arts, or your workout. Exercise isn’t exempt.”

At the time, that overstretch jumped out at me as the most obvious discomfort I had experienced during my workouts, so I assumed that was the culprit in accelerating twenty years of wear and tear. When I went back to training, dips and push ups, barbell and dumbbell presses, and dumbbell flyes all went on hiatus. I only did machine chest work if I could set a range limiter. Gradually I worked back up and got to where I could do all the exercises without discomfort, although with a much reduced-range than previously.

Give Your Joints a Break

If you suspect something in your workout is adding to your joint aches, you’re probably right. A vulnerable joint position is just that, whether you see it in sports, manual labor, martial arts, or your workout. Exercise isn’t exempt. The good thing about exercise is you can control the positions you put your joints in better than in those other activities.

“You may have to put aside trying to beat your personal records, and concentrate instead on the appropriate muscle action.”

Later that same summer, I fell while skating, landed on that same arm, and ruptured the triceps. At that point, I committed fully to a joint-friendly approach to training. I immersed myself in anatomy, biomechanics, and rehabilitation texts, eventually creating my own body of work on the subject (videos, manuals, blogs, talks), and that is now the exclusive approach I use on myself and clients.

RELATED: Why Your Mobility Work May Be Harming You

If you’re having some joint discomfort and you’ve ruled out anything that needs to be treated medically, it may be as simple as modifying or omitting an exercise. Look at every exercise you do and compare it to textbook muscle and joint function, and consider these general tips:

• Prevent the weight from pushing you into a painful range or an over-stretch position, even if it means using a shorter range.
• Deliberately stabilize your joints during a set, so the prime movers push against a stable, internal platform.
• Use enough weight to challenge the larger prime movers, but not so much that the deeper muscles are forced out of posture.
• In addition, you may have to change your attitude temporarily. You may have to put aside trying to beat your personal records, and concentrate instead on the appropriate muscle action.

It’s certainly viable to take a break from the more vigorous activity and work in a cycle of joint-friendly training. You’ll give your joints a break, you’ll stay in striking distance of top shape, and when the time comes, you can always go back to the more competitive approach. You can’t always fix a biceps, though.
