About this app

UNLOCK YOUR BODY'S NATURAL POTENTIAL

HGH Rush is the precision interval timer designed around peer-reviewed research showing that specific burst training protocols can increase natural Human Growth Hormone levels up to 10x above baseline.

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

THE SCIENCE-BACKED PROTOCOL

Research published in the Journal of Sports Sciences and European Journal of Applied Physiology demonstrates that 30-second maximum-effort bursts followed by 4-minute recovery periods create the optimal conditions for natural HGH stimulation.

This isn't another generic HIIT timer. HGH Rush implements the exact timing protocol used in clinical studies—because when it comes to hormonal response, precision matters.

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

WHY HGH MATTERS

Human Growth Hormone supports:
• Lean muscle development and preservation
• Enhanced fat metabolism
• Faster recovery from exercise
• Improved energy and vitality
• Better sleep quality

As we age, natural HGH production declines. Burst interval training is one of the most effective natural methods to stimulate your body's own HGH production—no supplements, no injections, just smart training.
