The reverse grip deadlift, more commonly called the mixed grip, isn’t inherently bad, but it does carry specific risks that a standard double overhand grip does not. The biggest concern is a distal bicep tendon rupture on the supinated (palm-facing-forward) arm, a well-documented injury pattern in heavy pulling. Beyond that, the asymmetrical hand position can create uneven muscle activation and subtle spinal rotation over time.
That said, millions of lifters use a mixed grip safely for years. Whether it’s a smart choice for you depends on how heavy you’re pulling, how you manage the risks, and whether better alternatives fit your situation.
The Bicep Tear Risk Is Real
The most serious risk of the mixed grip is tearing the distal bicep tendon on the supinated arm. A study published in the Orthopaedic Journal of Sports Medicine analyzed 24 bicep tendon ruptures captured on YouTube during deadlifts. Every single one occurred on the supinated arm. None happened on the pronated side.
The mechanism is straightforward. When your palm faces forward, your bicep is in a lengthened, vulnerable position while your elbow is fully extended. As you pull a heavy barbell off the floor, the load tries to straighten your arm further while your bicep reflexively contracts to stabilize the joint. This creates an eccentric contraction, where the muscle lengthens under load. Eccentric contractions generate forces roughly 80% greater than other types of muscle contractions, and that extreme tension is what snaps the tendon.
This doesn’t mean a tear is inevitable. It means the supinated arm is under a type of stress that the pronated arm simply isn’t exposed to, and the heavier you lift, the greater that stress becomes.
Asymmetry and Muscle Imbalances
Because one hand faces forward and the other faces back, the mixed grip loads your arms, shoulders, and upper back unevenly. Research in Frontiers in Sports and Active Living has documented bilateral asymmetries in arm muscle activation during mixed grip deadlifts. Over time, this asymmetrical loading can reinforce muscular imbalances, potentially leading to uneven hypertrophy and strength between your left and right sides.
The mixed grip can also generate slight hip rotation and uneven torso positioning during the pull. For a single heavy set, this is minimal. But if you deadlift with the same hand supinated every session for months or years, the cumulative effect adds up. One lifter who kept the same grip orientation for two years reported visibly different trap sizes on each side.
The mixed grip may also cause excessive tension patterns that extend beyond the arms. Research on deadlift grip variations has noted that the mixed grip can generate undue hip rotation alongside the bicep tendon stress, creating a pulling pattern that isn’t perfectly symmetrical through the spine and hips.
Elbow Hyperextension
Some lifters experience elbow hyperextension on the supinated side during heavy pulls. When the palm faces forward, the elbow joint is in a position where it can be forced past its normal range of motion if the load shifts or the bar wobbles. People who already have some degree of elbow laxity or hypermobility are particularly vulnerable. This isn’t a common injury, but it’s an uncomfortable and potentially dangerous sensation that catches some lifters off guard during their first attempts with the grip.
How to Reduce the Risks
If you choose to use a mixed grip, a few practical habits lower your injury exposure significantly.
Alternate which hand is supinated. The simplest approach is switching hands every set during your working volume. Save your preferred orientation for your heaviest singles if needed, but do everything else with the opposite setup. This distributes the asymmetrical loading more evenly and gives both bicep tendons similar exposure over time.
Use a double overhand grip for as long as possible. Many lifters can hold a double overhand grip through all their warm-up sets and lighter working sets, only switching to mixed grip for their top sets. If your double overhand fails at 300 pounds but your working sets are 275, you can do most of your training volume with a symmetrical grip and only use mixed grip when you truly need it.
Keep your elbows locked. Avoid any temptation to bend the supinated arm during the pull. A slight bend under heavy load is exactly what puts the bicep tendon at peak risk. Think of your arms as hooks, not levers.
Alternatives Worth Considering
Two common alternatives eliminate the asymmetry problem entirely.
- Hook grip keeps both palms facing you, removing the bicep tear risk completely. It works by trapping your thumbs between the bar and your fingers, creating a secure lock. The trade-off is significant discomfort, especially early on, and it requires at least average-sized hands to execute well. It’s extraordinarily secure once you adapt to it, but some lifters find it unreliable above 95% of their max. Hook grip is standard in Olympic weightlifting and increasingly popular in powerlifting.
- Lifting straps let you use a double overhand grip at any weight by wrapping fabric around the bar. Research published in Physiology & Behavior found that straps improve movement velocity and grip security during deadlifts. They’re ideal for training, since they remove grip as a limiting factor while keeping your body symmetrical. The downside: straps aren’t allowed in most powerlifting competitions, so competitive lifters still need to train a competition grip.
When Mixed Grip Still Makes Sense
For competitive powerlifters who can’t use straps on the platform and find hook grip unreliable at maximal loads, the mixed grip remains a practical choice. It’s consistently rated as the easiest grip variation to hold under maximal loads regardless of hand size, and it doesn’t require the painful adaptation period of hook grip. Even elite lifters who prefer hook grip sometimes fall back on mixed grip for their heaviest attempts. One competitive deadlifter who tore his bicep using mixed grip years ago still occasionally returns to it when hook grip fails at competition weights above 730 pounds.
The mixed grip isn’t dangerous in the way that, say, rounding your lower back under load is dangerous. It’s a grip style with a specific, well-understood risk profile. If you use it sparingly, alternate hands regularly, and keep your elbows locked, the odds of a serious injury are low. But if you have the option to train with straps or can tolerate hook grip, you get the same pulling strength with none of the asymmetry or bicep tendon concerns.
