Your VO₂ max, the maximum amount of oxygen your body can use during intense exercise, is a key indicator of cardiovascular fitness and longevity. Studies show that higher VO₂ max values correlate with lower mortality risk. Unfortunately, VO₂ max tends to decline with age, but dedicated training can slow this decline.
Why VO₂ max matters
-
Indicator of endurance: A higher VO₂ max means your muscles can work harder for longer by efficiently using oxygen.
-
Longevity marker: Research links cardiovascular fitness with longevity, maintaining aerobic capacity can contribute to a longer, healthier life.
-
Training stimulus: The only way to meaningfully increase VO₂ max is to exercise at or above your anaerobic threshold.
How RNWY Extra Mile™ supports hard efforts
While no supplement can raise VO₂ max by itself, RNWY Extra Mile™ provides targeted nutrients that help you push harder in training sessions designed to improve aerobic capacity. The formula contains:
-
6 g L‑Citrulline Malate: Supports nitric‑oxide production for improved blood flow and endurance.
-
Taurine & electrolytes: Maintain hydration and neuromuscular function during high‑intensity intervals.
-
Organic beet‑root powder & elevATP®: Provide natural nitrates and cellular energy support.
-
Dynamine™ & TeaCrine®: Offer clean mental focus and alertness without caffeine’s jitters, so your heart rate stays responsive during workouts.
-
Senactiv®: A proprietary complex to aid muscle recovery after intense sessions.
By fueling your body with these ingredients, Extra Mile™ helps you get the most out of threshold workouts. Because it contains no caffeine, athletes sensitive to stimulants can train at high intensities without unwanted heart‑rate spikes. Combining smart training with supportive nutrition is the best way to maintain or even improve VO₂ max as you get older.
