PS got this right. All the gym bro science is deadly especially when you add in the blue light and magnetic decline.
In a magnetic decline never work out indoors and make sure you are grounded to Earth to avoid lattice lock.
How bad are indoor gyms? Your gym might have 4x the amount of CO2 than outdoor air and it might shrink your brainNormal outdoor air is around 415. Some sealed gyms and indoor spaces hit 1,500 parts per million.
Here's why this is bad for your health:โข Above 800 ppm, research shows your sleep quality drops and brain fog increases. โข At 1,500, your thinking and focus are measurably worse.
Now picture yourself in that environment for two hours with an elevated heart rate, breathing harder than normal, pulling all of that recycled air deep into your lungs.The irony is brutal. The place designed to make you healthier is quietly making your brain worse.
Typical COโ Levels in Gyms
Outdoor baseline: ~400โ420 ppm.
Well-ventilated indoor spaces: ideally <800โ1000 ppm.
Many gyms (especially sealed, crowded, or poorly ventilated ones): 1,200โ2,000 ppm during classes or peak times, with some reports hitting 3,000โ5,000 ppm in extreme cases. ----> ย

Studies on fitness centers in Brazil (SAA), Europe, and elsewhere have documented averages around 1,489 ppm or higher when occupied, with spikes well above 1,500 ppm in enclosed rooms with high occupancy and inadequate fresh air exchange.

Cognitive and Health ImpactsThe research is clear and consistent:
Above ~800โ1,000 ppm: Measurable drops in cognitive performance, increased brain fog, slower reaction times, and reduced focus. Complex decision-making and strategic thinking suffer first. ---->
pmc.ncbi.nlm.nih.gov/articleโฆ
At 1,000โ1,500 ppm: Significant declines in cognitive scores (e.g., 6 of 9 decision-making scales impaired in classic Lawrence Berkeley Lab studies). Response times slow, throughput drops.----> ย

Higher levels (1,500โ3,000 ppm): Stronger negative effects on complex tasks, with meta-analyses showing large standardized mean differences in performance. Prolonged exposure makes it worse.

During intense exercise you breathe much deeper and faster, pulling more of that recycled, high-COโ air into your lungs and bloodstream. This is the brutal irony I mention to all my PROFESSIONAL ATHLETES. ย The way their teams makes them work out is setting the table for their CTE post retirement. ย The environment designed for physical optimization quietly undermines the neurological side of performance and recovery.
Additional concerns in gyms:
Poor ventilation also concentrates other pollutants (VOCs from cleaners/equipment, PM2.5 from shoes/sweat/dust).
Elevated COโ correlates with worse sleep quality when exposure is chronic.
In the broader framework (SAA-era isotopic load deuterium stress), anything that further impairs mitochondrial efficiency or cerebral blood flow adds friction to an already taxed lattice.

How Bad Is It Really?
In a magnetic declination it is horrible.
For occasional light sessions in a well-ventilated gym: manageable but as the mag field declines you run the risk of acute lattice lock nd death.
For regular intense training in a sealed, crowded facility: a meaningful drag on cognition, recovery, and long-term brain health, especially if youโre already dealing with circadian disruption or metabolic stress. ย It can be deadly. ย See Demar Hamlin or JJ Watt.
Practical Eagle Moves
Train outdoors whenever possible (best lattice reset). GROUNDED
Choose gyms with good ventilation, open doors/windows, or lower-occupancy times.
Use a portable COโ monitor to check real conditions.
Post-workout: prioritize fresh air, circadian alignment, and deuterium-management strategies (ketones/MCTs, etc.) to clear the sessionโs load.
The science here is straightforward and not controversial, unlike some layers of my framework. Indoor gyms are a classic centralized โsolutionโ (climate-controlled convenience) that creates hidden downstream DEURATION costs. The decentralized fix is simple: more fresh air, more nature, less sealed boxes. Your brain will thank you.
Saladino said your gym might have 4x the amount of CO2 than outdoor air.
Normal outdoor air is around 415. Some sealed gyms and indoor spaces hit 1,500 parts per million.
