Plyo Box
A plyo box is a sturdy elevated platform used for box jumps, step-ups, and depth jumps. It develops the explosive lower body power HYROX athletes need for Burpee Broad Jumps, Sled Push drive, and efficient running mechanics.
Definition
A plyo box (plyometric box) is a sturdy elevated platform used for box jumps, step-ups, depth jumps, and other explosive lower body exercises. Available in foam, wood, and steel construction at heights ranging from 30 to 76 cm, the plyo box is a core training tool for developing the reactive power and single-leg strength that HYROX® athletes need for Burpee Broad Jumps, running efficiency, and explosive station transitions.

How It Is Used in HYROX®
The plyo box is not used directly in HYROX® competition stations. Its training applications include:
- Box jumps - develop lower body explosive power and reactive strength for Burpee Broad Jumps.
- Step-ups - build single-leg strength and stability for running and Sandbag Lunges.
- Depth jumps - advanced plyometric drill that trains the stretch-shortening cycle for more powerful push-offs.
- Box squat - sit-to-stand with a barbell or bodyweight to develop concentric power from a dead stop, mimicking the leg drive of Sled Push.
- Elevated push-ups or dips - upper body conditioning variations.
Home Gym Alternatives
- Sturdy park bench or concrete step - for step-ups and elevated exercises.
- Stack of bumper plates - creates a stable, adjustable-height platform.
- Staircase - single or double steps for step-ups and calf raises.
- DIY wooden box - built from plywood for under $30 in materials.
HYROX® Context
Plyometric training is the bridge between strength and speed for HYROX® athletes. Sled pushes require explosive leg drive, Burpee Broad Jumps demand horizontal power, and running efficiency depends on elastic energy return with each stride. A plyo box enables all of these training stimuli. Including 2-3 sets of box jumps or depth jumps at the start of 2 sessions per week (before fatigue sets in) develops the neuromuscular power that makes every station and running segment more efficient.
FAQ
What height plyo box should I use? For HYROX® training, a 50-60 cm box suits most athletes for jumps and step-ups. Beginners should start at 40-50 cm and progress. Foam boxes are recommended for high-rep work to protect shins.
Are box jumps safe for HYROX® athletes? Yes, when performed with proper technique. Step down (do not jump down) to reduce impact, use a box height you can consistently land on with control, and perform them when fresh (early in the session).
How often should I do plyometric training? 2-3 times per week during build phases, with 3-5 sets of 3-5 reps per exercise. Reduce to 1x/week during taper. Always allow 48+ hours between plyometric sessions.
