Body Composition
Body Composition — The ratio of fat mass to lean mass (muscle, bone, water) in the body. For HYROX®, optimizing body composition—more muscle, less excess fat—improves power-to-weight ratio.
Definition
This is a resistance-training movement. Joint positions, range, tempo and load change the task, and several muscles contribute; the movement does not isolate one muscle.

Programming
Use a controlled, pain-free range and choose load, repetitions and progression for the individual goal and response. No fixed dose fits everyone, and this exercise does not guarantee injury prevention or HYROX® performance.
