P

Plank Shoulder Taps

From a high plank, touching each hand to the opposite shoulder forces the core to resist rotation while the shoulders stabilize.

Exercises

Plantar Flexion

Plantar flexion is an ankle movement that lifts the heel or points the toes downward; the gastrocnemius and soleus are its primary muscles.

Fitness Science

Plantarflexion

Plantar flexion is ankle movement that points the foot away from the shin.

Fitness Science

Plate Halo

Shoulder warm-up drill that circles a weight plate around the head to loosen the thoracic spine and activate the shoulder stabilisers.

Exercises

Plyo Box

A sturdy elevated platform used for box jumps, step-ups, and depth jumps. Available in various heights for scaling plyometric training intensity.

Equipment

Plyometrics

Explosive jump-based exercises (box jumps, bounds, depth jumps) that train the stretch-shortening cycle. Builds the reactive power needed for fast HYROX® transitions.

Training

Positive Split

Running the second half of a race slower than the first half. Common in HYROX® when athletes start too fast and fatigue accumulates through later stations.

Training

Posterior

Posterior means toward the back of the body or behind another structure in anatomical position.

Fitness Science

Posterior Chain

Posterior chain is a coaching term for muscles on the back of the body, commonly including the gluteals, hamstrings, spinal extensors and calf muscles.

Fitness

Power Output

Mechanical power is the rate of doing work. In movement it can be expressed from force and velocity, but the result depends on what body or implement is measured and how.

Fitness

Power-to-Weight Ratio

The amount of power an athlete can produce relative to their body weight. Critical for HYROX performance across running and bodyweight-dependent stations.

Performance Science

Progressive Overload

Gradually increasing training stress (weight, volume, intensity) over time to drive continued adaptation and improvement.

Training

Pronation

The natural inward roll of the foot during running. Overpronation increases injury risk during the 8 km of HYROX® running - proper footwear and ankle strength help control it.

Fitness Science

Prone

Prone means lying face down. In exercise, it describes body orientation rather than a specific muscle action, difficulty or training effect.

Fitness Science

Prone Y-T-W Raise

A prone Y-T-W raise is a sequence of arm lifts performed face down in Y, T and W positions to train scapular and shoulder control.

Exercises

Proprioception

Proprioception is sensory information about body position and movement arising from multiple receptors and integrated by the nervous system.

Fitness Science

Prowler Sled

A Prowler is a training sled used for pushes and drags. Check the actual model, runners and attachment options before using its specifications or comparing it with HYROX equipment.

Equipment

Pull Up

Hanging from a bar and pulling the chin above it develops the lats, biceps and grip, a foundational measure of upper-body pulling strength.

Exercises

Pull-Up Bar

An overhead bar used for pull-ups, chin-ups, and hanging exercises. A staple in functional fitness and HYROX accessory training.

Equipment

Push Up

A push-up is a bodyweight horizontal press performed while the hands and feet support the body. It trains the chest and triceps while the shoulders and trunk help control the movement.

Exercises

R

Race Day Nutrition

The planned fueling strategy before and during a HYROX race, including pre-race carb loading, hydration, and intra-race energy gels or drinks.

Training

Race Pace

The target speed or effort level planned for each running segment during a HYROX event.

Training

Race Venue

A race venue is the event-specific building and course used for a HYROX race. Layout, lap count, access and facilities can vary, while the official race sequence remains governed by the rulebook.

Race Format

Rack Pull

A compound exercise used in HYROX training. One of the 104 core exercises in the Repz training database.

Exercises

Range of Motion

Range of motion is the angular or linear excursion available or used at a joint during a defined movement; measurement method and task must be stated.

Fitness Science

Rate of Force Development

How quickly a muscle can produce maximum force. Critical for explosive HYROX® movements - sled starts, wall ball throws, and transitions between stations.

Training

Rate of perceived exertion: recording training load

Rate of perceived exertion records how demanding exercise feels. Session RPE applies that assessment to a whole workout and can be combined with its duration.

Performance Science

Recovery Phase (Rowing)

Recovery is the return from the rowing finish to the catch: arms extend, the body hinges forward, then the knees bend.

Equipment

Rectus Abdominis

Rectus abdominis is a paired vertical muscle of the anterior abdominal wall. It flexes the thoracic and lumbar spine and participates in coordinated trunk function.

Muscles

Renegade Row

Combines a plank on dumbbells with alternating single-arm rows, so the back works while the core resists rotation.

Exercises

Resistance Band

A resistance band is an elastic implement whose tension generally changes as it is stretched; actual resistance depends on the band and elongation.

Equipment

Resting heart rate: measurement and interpretation

Resting heart rate is the number of heartbeats per minute while resting. Fitness, medication, health and measurement conditions affect it; a lower value is not always better.

Performance Science

Reverse Crunch

Rolling the knees toward the chest and lifting the hips off the floor puts more emphasis on the lower abs than a standard crunch.

Exercises

Reverse Plank

Facing upward with hips lifted and weight on the palms and heels, this hold strengthens the glutes, hamstrings and the back side of the core.

Exercises

Rhomboids

The rhomboid major and minor are upper-back muscles that connect the spine to the medial border of the scapula. They contribute to scapular retraction, downward rotation and shoulder-girdle stability.

Muscles

Rotation

Rotation is a twisting movement around a central axis, such as trunk rotation during Russian twists or internal/external shoulder rotation.

Fitness Science

Rotator Cuff

The rotator cuff comprises supraspinatus, infraspinatus, teres minor and subscapularis. These muscles move the shoulder and contribute to dynamic stability of the glenohumeral joint.

Muscles

Rowing Stroke

A rowing stroke is one complete cycle on a rowing ergometer: catch, drive, finish and recovery.

Equipment

RPE: rating effort during HYROX training

RPE means rating of perceived exertion: your assessment of how hard exercise feels. The number only makes sense when the scale and the task are specified.

Training

Running Efficiency

How effectively a runner converts energy into forward motion. Improved through cadence work, strength training, and proper gait mechanics - saving energy between HYROX® stations.

Training

Russian Kettlebell Swing

Hip-hinge swing that snaps the kettlebell to chest or eye level using glute and hamstring power, with the arms acting only as a link to the bell.

Exercises

Russian Twists with Wall Ball

A core exercise used in HYROX training. One of the 104 core exercises in the Repz training database. Directly supports the Wall Balls station.
