When New Zealand’s summer heat kicks in, training sessions can take a serious toll on your body. Sweat rates rise, hydration drops, and fatigue can hit faster than you’d like. That’s where electrolytes for hydration and performance come in — helping you replace what you lose and perform at your best, no matter how hot it gets.
HYROX challenges the full spectrum of athletic ability — speed, strength, and mental resilience — across 8 × 1 km runs and 8 functional stations. Training hard is non-negotiable, but micronutrition is the missing edge for many athletes. This guide unpacks the essentials: iron, magnesium, and electrolytes. You’ll learn how each supports energy production, hydration, muscle function, and cramp prevention — especially critical for plant-forward or non-meat eaters who may be at greater risk of low iron.
When you start exploring amino acid supplements, you’ll quickly run into two acronyms:
EAAs (Essential Amino Acids) and
BCAAs (Branched-Chain Amino Acids). On the surface, they sound similar — but they do different jobs, and choosing the right one (or knowing if you need both) can make a difference for your performance, recovery, and muscle health.
