Hip Thrust Load-Velocity Profile: Testing From 30% to 85%

The barbell hip thrust has become a staple of glute-focused strength programming, but most lifters still load it with the same trial-and-error approach they use for squats: add weight until a set feels hard, then guess at the next session. A load-velocity profile replaces that guesswork with data. By recording bar speed across a range of loads, you can map exactly how your hip thrust responds to intensity, estimate your daily one-rep max without a maximal test, and prescribe working loads that match your actual readiness rather than a number from weeks ago.

The research below explains why the hip thrust needs its own velocity zones rather than borrowed squat numbers, then walks through a 30-minute testing protocol and the readiness checks that turn a single measurement into that day's working load.

A load-velocity profile (LVP) is the individual relationship between the load lifted (expressed as %1RM or absolute kilograms) and the mean concentric velocity (MCV) the bar travels at that load. For the hip thrust, this relationship is built by measuring bar speed across an ascending series of loads and fitting a regression line through the results. Once the line is established, you can read a working load's expected velocity directly from the profile, or work backward from a measured velocity to estimate the load that produced it.

Loturco et al. (2019), publishing in the International Journal of Sports Physiology and Performance, measured bar velocity and power output across a full loading spectrum in the barbell hip thrust and found that peak power occurred at a mean velocity of approximately 0.92 m/s and a mean propulsive velocity of 1.02 m/s, with peak velocity reaching 1.72 m/s. These values give coaches a validated reference point for identifying the optimal power-training load in the exercise, rather than relying on a fixed percentage that ignores individual variation.

More recently, Nieto-Acevedo et al. (2023), writing in the International Journal of Environmental Research and Public Health, tested load-velocity relationships in the hip thrust and deadlift in 32 trained adults and reported strong, highly linear relationships in both lifts (R² range of 0.88 to 0.94). This linearity is what makes velocity-based load prescription practical: a small number of submaximal data points is enough to predict the full curve with confidence.

Coaches who are used to squat or deadlift velocity zones are often surprised by how fast the hip thrust moves at comparable relative intensities. There are two structural reasons for this.

First, the hip thrust is a short-range, hip-dominant movement performed from a supported position, which removes the balance and bracing demands that slow down free-standing lifts. Contreras et al. (2015), in a widely cited electromyography comparison published in the Journal of Applied Biomechanics, found that the barbell hip thrust produced significantly greater gluteus maximus activation than the back squat, while the back squat produced greater vastus lateralis (quadriceps) activation. Because the hip thrust isolates hip extension rather than distributing load across the knee and hip simultaneously, the bar can accelerate through a shorter, more mechanically efficient path.

Second, the Nieto-Acevedo et al. (2023) data noted above found no significant difference between men and women in hip thrust velocities at any relative load, in contrast to the deadlift, where men moved lighter loads (30 to 50% 1RM) significantly faster. Practically, this means a single set of hip thrust velocity zones can be used with confidence across mixed-sex training groups, whereas deadlift zones may need sex-specific adjustment.

The net effect is that hip thrust minimum velocity thresholds (the bar speed recorded at true 1RM) tend to sit noticeably higher than deadlift or squat thresholds, and coaches transferring zones from another lift without re-testing will consistently under-load the exercise.

Building a reliable profile takes one focused session and roughly 25 to 30 minutes once you are warmed up. Follow this sequence:

1. Warm up thoroughly. Include glute bridges, banded lateral walks, and two to three ramping sets of hip thrusts with the empty bar or a light pad-only load.
2. Select five loads spanning 30 to 85% of estimated 1RM. A typical spread is 30%, 45%, 60%, 70%, and 85%.
3. Perform 2 to 3 reps per load with maximal concentric intent, resting 2 to 3 minutes between loads to avoid accumulated fatigue contaminating the profile.
4. Record mean concentric velocity for every rep using a linear position transducer or an IMU-based sensor attached to the bar, then keep the fastest clean rep from each load.
5. Plot load against velocity and fit a linear regression. The x-intercept at your minimum velocity threshold is your estimated 1RM.

Keep hip position, foot placement, bar padding, and thoracic contact point on the bench identical across sessions. Small setup changes shift the moment arm and will distort the profile more than an actual change in strength would.

These ranges are population estimates drawn from the Loturco et al. (2019) and Nieto-Acevedo et al. (2023) datasets; your own regression line, built from your own reps, is always the authoritative reference for prescribing your training loads.

Once your regression line is built, two numbers matter most: the minimum velocity threshold (MVT), which is the velocity your bar reaches at true 1RM, and the slope, which describes how quickly velocity drops as load rises.

Because the Loturco et al. (2019) data places optimal power output around 0.92 to 1.02 m/s in the hip thrust — noticeably faster than the 0.30 m/s squat or 0.17 m/s bench press benchmarks many lifters are used to — using borrowed velocity zones from another lift will misclassify your training intensity. A 0.85 m/s rep might represent a genuinely heavy set on the squat, but on the hip thrust it is likely closer to a moderate 50 to 60% 1RM effort.

To estimate your daily 1RM before a working set, perform 2 to 3 reps at a fixed reference load (60 to 70% of your last tested 1RM) and compare the resulting MCV to your stored profile. If today's velocity at that load sits within 3% of your profile's expected value, proceed with the session as planned. A drop of 5 to 10% below the profile line signals reduced daily capacity; reduce planned working loads by a proportional 5 to 8% rather than forcing the prescribed percentage.

With a validated profile in hand, you can prescribe hip thrust training in velocity zones rather than fixed percentages. Based on the power-output data from Loturco et al. (2019), a practical zone breakdown looks like this: 1.10 to 1.40 m/s for explosive-strength and rate-of-force-development work, 0.90 to 1.05 m/s for the power zone (bracketing the 0.92 to 1.02 m/s peak-power window identified in that study), 0.65 to 0.85 m/s for general strength-hypertrophy work, and below 0.60 m/s for maximal-strength blocks approaching true 1RM.

Velocity-loss thresholds work the same way they do in other compound lifts: choose the cutoff based on your goal and terminate the set once the first rep of a series drops by that percentage. A 10 to 15% velocity-loss threshold suits power-focused blocks, 20 to 25% suits general strength and moderate hypertrophy work, and 30% or higher trades additional fatigue for a stronger metabolic stimulus. Because hip thrust velocities are fast and reps accumulate quickly at lighter loads, coaches often find that a fixed velocity-loss percentage produces noticeably more total reps per set on this exercise than on the squat or deadlift at an equivalent relative intensity — which is expected given the shorter range of motion and lower systemic fatigue cost of the movement.

Re-test your full profile every 4 to 6 weeks, or immediately after a training block transition, since a meaningful strength change will shift the entire regression line rather than a single point on it.

A handful of setup and execution errors account for most inaccurate hip thrust profiles:

• Inconsistent hip drive intent. Because the hip thrust is often performed as an accessory movement, lifters sometimes default to a controlled, sub-maximal push even on lighter loads. Every profiling rep must be driven with full concentric intent, or the resulting velocities will be artificially slow and the regression line will underestimate your true 1RM.
• Shifting bench or foot position between sessions. Even a few centimeters of change in shin angle at lockout alters the moment arm and shifts velocity independent of any change in strength. Mark your foot position and bench height and replicate them exactly.
• Testing while fatigued. Profile the hip thrust at the start of a session, before other lower-body work, so residual fatigue from prior sets does not depress submaximal velocities and distort the curve.
• Borrowing zones from the squat or deadlift. As the Loturco et al. (2019) and Nieto-Acevedo et al. (2023) data both confirm, hip thrust velocities run substantially faster than other compound lifts at matched relative loads. Build an exercise-specific profile rather than reusing thresholds from a different movement.

Followed consistently, these adjustments keep your profile accurate enough to drive real programming decisions rather than serving as a one-time novelty measurement.
