Ask most powerlifters about curls and you’ll get a smirk. “Biceps are for bodybuilders.” Here’s the thing: powerlifters don’t need big biceps, but they absolutely need biceps that can survive heavy training without blowing up. Direct bicep work for a powerlifter isn’t about vanity, it’s about durability, elbow health, and staying in the game. Let me make the case.
The Myth: Biceps Are Just Mirror Muscles
The old-school view treats biceps as pure ornamentation, something you train to fill a t-shirt, irrelevant to the squat, bench, and deadlift. For a powerlifter chasing a bigger total, arm size genuinely isn’t the priority. That part’s true.
But “not the priority” got twisted into “totally unnecessary,” and that’s the mistake. Skipping all direct bicep work leaves a weak link that heavy pulling and pressing will eventually find. Optional doesn’t mean useless.
What Biceps Actually Do Under a Heavy Bar
Your biceps do real work in the big lifts, even if they’re not the star:
- Bench press: the biceps help stabilize the shoulder and control the bar path. Weak, cranky biceps make a heavy bench feel shakier.
- Deadlift: the biceps are involved isometrically in holding the bar, and they’re under real tension, especially with a mixed grip.
- Rows and pulls: all that back work hammers the biceps tendon whether you train arms directly or not.
Strong, resilient biceps tendons help you tolerate all of that. You don’t need 20-inch arms, you need arms that don’t break down.
The Real Reason: Injury Prevention & Elbow Health
This is the whole argument in one line: direct bicep work is prehab. Powerlifters accumulate a ton of pulling volume in pronated (palms-down) positions, which can overload the biceps tendon and irritate the elbow. A bit of controlled, strict curling strengthens the tendon and balances all that pressing and pulling, which can calm down elbow tendonitis and keep you training instead of resting on the couch.
The goal isn’t a pump. It’s building a tendon that tolerates heavy work so a minor tweak doesn’t cost you a training block. For lifters who already deal with elbow pain, that’s huge.
The One Rule You Must Not Break
Here’s the single most important safety point in this whole article: never deadlift heavy immediately after curling. A pre-fatigued biceps under a mixed-grip deadlift is exactly how lifters tear a biceps tendon, one of the ugliest injuries in the sport. Keep your direct bicep work well away from your heavy pulls: do it at the end of a session, or on a different day entirely. Respect that and you get all the benefit with none of the catastrophe.
Who Needs This Most
Some lifters need direct bicep work more than others. Watch for these signs:
| Sign | What It Suggests |
|---|---|
| Nagging elbow pain after pulls | Overloaded biceps tendon |
| High weekly row and chin-up volume | Lots of indirect bicep stress |
| Frequent mixed-grip deadlifting | Uneven biceps tendon load |
| A history of elbow tendonitis | Needs prehab and balancing |
| Lots of pronated pulling, no supinated work | A muscle imbalance |
If several of these ring true, you’re a prime candidate to add a little arm work.
The Short Version of How
The full programming deserves its own guide (see my breakdown on training biceps for powerlifting), but here’s the essence: a few sets of strict curls once or twice a week, kept light to moderate with perfect form, placed at the end of your session and away from heavy deadlifts. Chin-ups and chest-supported rows build the biceps too, so count those toward your total. Start light, progress slowly, and back off if your elbows complain.
And no, this won’t turn you into a bodybuilder. If you’re curious why those guys are bigger despite you being stronger, I broke it down in why bodybuilders are bigger than powerlifters.
Wrapping It Up
Powerlifters don’t train biceps for the mirror, they train them to stay healthy and keep pulling and pressing heavy for years. A small dose of strict, well-placed bicep work strengthens the tendon, balances all your pulling, and helps keep elbow pain from stealing your training time. Just never stack it right before a heavy deadlift. Add a couple of sets a week, treat it as prehab, and protect your total. Now go move some heavy ass weight. Let’s do this.
