T
T-Bar Row
A T-bar row is a horizontal pulling exercise performed with a lever-style bar or dedicated machine. Setup, support, handle, path and muscle loading differ across designs.
Tabata
Tabata commonly denotes repeated 20-second work intervals separated by 10 seconds, but exercise mode and intensity must be stated.
Taper
A 1-3 week reduction in training volume before race day while maintaining intensity. Allows full recovery so HYROX® athletes peak on competition day.
Tapering
Reducing training volume in the 1-2 weeks before race day to allow full recovery while maintaining fitness.
Tempo Run
Sustained run at a comfortably hard pace near lactate threshold, typically 20 to 40 minutes, used to build the steady race speed HYROX demands.
Tempo Training
Tempo training means deliberately controlling pace or phase duration; the term must specify whether it refers to running intensity or resistance-exercise repetition timing.
Tendon
Tough connective tissue that attaches muscle to bone. Tendons store and release elastic energy during running and jumping - essential for HYROX® performance.
Testosterone
A hormone that drives muscle growth, recovery, and energy. Natural levels are optimized through sleep, heavy compound lifts, nutrition, and managing training stress.
Thoracic Spine
The thoracic spine is the twelve-vertebra region between the cervical and lumbar spine.
Threshold Training
Training at or near lactate threshold intensity to improve the body's ability to sustain high effort over extended periods.
Tibialis Anterior
Tibialis anterior is the largest muscle in the front compartment of the lower leg. It dorsiflexes and inverts the foot and contributes to foot clearance and controlled loading during gait.
Time Under Tension
The total time a muscle is under load during a set. Controlled tempos increase TUT for greater hypertrophy stimulus.
Toes to Bar
Toes-to-bar is a hanging exercise in which the feet move from behind the vertical plane of a bar to contact the bar between the hands.
Training Density
Training density describes how much work is performed per unit of time or, more broadly, the relationship between work and recovery within a session. The exact calculation must be stated.
Training Intensity
The level of effort or load in a workout, measured by weight, heart rate zone, pace, or RPE. Must be balanced with volume and recovery for HYROX® progress.
Training Load
The cumulative stress placed on the body from training, measured by volume, intensity, and frequency. Managing training load prevents overtraining and injury.
Training Volume
The total amount of work performed (sets × reps × weight, or total distance/time). The primary driver of adaptation when managed alongside recovery.
Transverse Abdominis
The transverse abdominis is the deepest abdominal muscle that wraps around the torso like a corset, providing core stability and spinal support.
Transverse Plane
The transverse plane is an imaginary horizontal plane that divides the body or an organ into upper and lower portions. Rotation around a longitudinal axis is commonly described in this plane.
Trap Bar
A trap bar is a frame-shaped barbell that lets the lifter stand inside the load and use neutral handles; geometry varies by model.
Trap Bar Deadlift
A pull exercise used in HYROX training. Transfers to the Sled Pull station.
Trapezius
The trapezius is a broad superficial muscle with regions that contribute differently to scapular and neck movements depending on the task.
Tricep Extension Machine
A triceps-extension machine provides external resistance while the user extends the elbow. It primarily trains the triceps brachii, but design, setup and available range vary by machine.
Tricep Pushdown
Cable machine exercise where you push a bar or rope downward to fully extend the elbow, isolating all three heads of the triceps.
Triceps
Triceps brachii is a three-headed muscle on the back of the upper arm. Its long, lateral and medial heads join in a tendon attaching to the olecranon and together extend the elbow.
Triple Extension
Triple extension describes concurrent or closely sequenced extension at the hip, knee and ankle during a movement; timing and contribution vary by task.
Tuck Jump
A tuck jump is a vertical jump in which the knees are drawn upward during flight before landing under control.
U
Undulating Periodization
Undulating periodization varies resistance-training volume or intensity more frequently than a traditional linear model, commonly from session to session or week to week.
Unilateral Training
Unilateral training loads or practises one side or limb at a time; bilateral training uses both sides together. Exercise choice should match the target task and athlete.
V
V-Up
Demanding core move in which the legs and torso rise together to form a V shape, requiring strong abs and hip flexors plus good compression.
Valgus
Valgus is an inward collapse of a joint, most commonly knee valgus (knees caving inward) during squats, lunges, or landing from jumps.
Ventilatory Threshold
The exercise intensity at which breathing rate increases disproportionately to oxygen consumption. Closely related to lactate threshold.
VO₂ max: oxygen uptake and HYROX performance
VO₂ max is the maximum rate of oxygen uptake during exercise. It describes aerobic capacity, not a guaranteed race time or a complete measure of HYROX ability.
VO₂max training: evidence and realistic expectations
VO₂max can respond to endurance training, but the amount of change varies. Training studies describe groups and protocols, not a guaranteed improvement for every athlete.
W
Wall Ball Slam
A compound exercise used in HYROX training. One of the 104 core exercises in the Repz training database. Directly supports the Wall Balls station.
Wall Ball Thruster
An informal name for a squat-and-throw wall-ball exercise; HYROX officially calls the station Wall Balls.
Wall Sit
A bodyweight squat exercise used in HYROX training. One of the 104 core exercises in the Repz training database.
Warm-Up
A warm-up is preparatory activity performed before the main training or competition.
Weight Plate
A flat disc loaded onto barbells and machines to add resistance. Available in standard and Olympic sizes, used to load sleds, barbells, and for plate-based exercises.
Weighted Pull Up
Adding load with a dip belt, vest or dumbbell turns the pull-up into a heavy strength lift for the lats, biceps and grip.
What Is Threshold Pace?
The running pace at or near lactate threshold - the fastest sustainable effort for roughly 30-60 minutes. Key for pacing HYROX run segments at competitive intensity.
Wide Grip Pull Up
Pull-up with hands placed outside shoulder width, increasing lat activation and reducing bicep contribution compared to a standard grip.
Work Capacity
Work capacity is context-specific ability to sustain and repeat the work required by a defined task; it has no single universal test or score.
Workout Station
One of eight functional fitness stations in a HYROX race, performed between 1km running segments.
World Record
The fastest-ever HYROX completion time in a specific division, recognized officially by the HYROX organization.
World's Greatest Stretch
A bodyweight compound exercise used in HYROX training. One of the 104 core exercises in the Repz training database.
Z
Zone 1 Training
Zone 1 usually means the easiest band in a chosen intensity model, but its heart-rate boundary is not universal. Use the definition supplied by your tested or configured system.
Zone 2 Training
Low-intensity aerobic training at 60-70% of max heart rate. Builds the endurance base critical for HYROX running segments.
